A separate default-off pilot permits one exact saved monthly Core PCE target, 28 attempts and a fixed seven-day UTC window one day before through six days after the confirmed BEA date, with enrollment at most 45 days before that window. This is an operational window, not source publication time. The same six-hour/shared capacity applies without changing the Fed/GDP pilot. Only explicit authorized watch creation starts it; reads/saves and owner-shared human Check grants never do. Preserve pending only for a newer successful exact BEA schedule read; repeated clocks are cached and missing sources incomplete.

Exact version and research:read key required; key stays out of public reads. One private GET then one keyless source GET, followed by shared local comparison. Preserve saved_version, scope, comparison observation/status and unavailable errors. No save, watch, paid model or new HTTP endpoint; plain read remains retained-only.

Decimal quantity is positive, at most 1000000 shares and 8 decimal places. Buy consumes asks, sell consumes bids of the selected native outcome. Both books retain their own timestamps; stale depth cannot supply an estimate. With include_cost=true read filled/unfilled shares, gross collateral, an estimated purchase fee and covered cost when the exact CTF/CLOB fee model is confirmed; otherwise fees/cost stay unknown. Add include_proceeds=true with include_cost=true for the sale_proceeds object and modeled sale fees: covered gross minus fee, with full-size net only when depth covers the request. Without the extra flag sale fees retain their unknown state. Retain fee-source times and minimum-order/tick metadata. Omitting include_cost preserves the v1 response.

Protocol V2 position-ID markets return unsupported_contract.","For a new supplied contract, GET /api/free/v1/research/evidence?market=<retained canonical ID/public slug or exact native slug/https://polymarket.com/market/slug>. Retained references require an active/archive native mapping and exact live condition identity; unknown mappings fail without substitution. The first source policy supports the explicit Federal Reserve calendar URL named in contract text. Keep status, gaps, capture times and the full evidence bundle; partial or unsupported is not verified meaning. No account write, model call or Check publication occurs.","For two already retained evidence responses, JS/CLI/MCP 0.1.9 and later can compare locally: named JS export compareSourceEvidence(previous, current), CLI howsure evidence-compare first.json repeat.json, or MCP howsure_compare_source_evidence with previous/current raw objects. Supply complete raw howsure.evidence-request.v1 responses for the same exact contract, not IDs, evidence bundles, private documents or a mixed-task wrapper. From the guide's task receipt extract response.evidence.data after checking response.evidence.ok. No HTTP endpoint, new source read, baseline replacement, account save or automatic monitoring is involved. The CLI reads its files and prints JSON without rewriting them.

Capabilities describe product support, not live availability; collection flags do not describe the separate bounded on-demand depth read.","Discover /api/free/v1/checks, optionally filtered by exact market_id, and read a returned Check URL. version_count and its legacy alias count measure returned published versions; unique_market_count counts their distinct canonical market IDs. These registry reads do not require a working market-data connection. An empty registry match means no published Check, not no market.","Use a returned updates URL to inspect current contract applicability, newer published versions, and bounded source observations. It reads existing serving data, never refreshes sources or creates a new Check. Retain the fixed Check and its own reviewedAt timestamp separately.","Check /api/health/howsure.

Use distinct canonical IDs, not venue URLs or public slugs. The response uses the same howsure.contract-comparison.v1 snapshot as the web comparison; it reads retained serving data only and saves nothing. A 404 names missing IDs without substitution; 503 means comparison is unavailable. A 200 can contain stale, archived, unknown or missing observations; inspect each contract and field.","Optional include_rules=true&rules_version=2 on GET /api/free/v1/contracts/compare adds complete recognized Fed meeting/annual, GDP, Brazil-election and House-control rule readings without source requests. Same-year Fed annual/meeting comparisons keep distinct horizons and conditions; compatible scenarios are hypothetical, never outcomes or equivalent payouts. Candidate/party pairs are not assumed exhaustive. JS/CLI/MCP 0.1.13 and Python 0.1.9 request revision 2 using their existing includeRules/include_rules option. Older HTTP requests without rules_version retain the original Fed/GDP format. New snapshots contain parserVersion:2; original snapshots remain readable. Omitted/false keeps raw fields only. Preserve exact IDs, null columns, observations and limitations. A missing/malformed requested block is an error, never silent fallback.","Explicit include_decision=true on the evidence endpoint adds one bounded official statement or target-range context read for a recognized Fed meeting. JS/CLI/MCP 0.1.14 use includeDecision:true and Python 0.1.10 uses include_decision=True. Preserve collection_scope:fed_decision, source times and optional contract_reading.decision. Current range before a future meeting is provisional; unavailable statements do not establish the no-statement exception. Settlement remains false. Default reads and automatic watches retain the original two-source Fed/GDP policy; decision-source saved baselines cannot enable that watcher.","JS/CLI/MCP 0.1.15 adds includeDecision:true to the existing local compareSourceEvidence/howsure_compare_source_evidence operation (CLI evidence-compare --include-decision true). Default/false keeps v1; true adds decision_comparison in source-evidence-comparison.v2. Facts are rebuilt from retained passages; first observed in two captures is not first publication. Preserve no_new_observation/incomplete/not_comparable and separate contract wording from bounded condition assessment. No source read, author-thesis verdict or settlement is inferred.","Explicit include_release=true on the existing evidence endpoint reads the official BEA index and exact quarter Advance release. JS/CLI/MCP 0.1.15 uses includeRelease:true; Python 0.1.11 uses include_release=True. Keep collection_scope:gdp_release, source timestamps and contract_reading.release. Advance observation and later revision stay separate; absence does not establish a fallback. Cannot combine with include_decision=true. Default policy and automatic watches are unchanged.","The explicit include_pce_release and include_cpi_release scopes on the existing research evidence read were introduced in JS/CLI/MCP 0.1.19, Python 0.1.13 and OpenAPI 1.14.0. They remain mutually exclusive with each other and Fed/GDP release scopes. The current service policy follows the declared exact period. Complete known Core PCE/Core CPI MoM equality or exact 0.6% or more terms bind month/year, core monthly measure, one-decimal precision and the delayed fallback. PCE follows the exact BEA schedule link; CPI follows the official BLS index to its exact selected-period archive when listed, otherwise the current summary. The archive path date, printed release date, reference period and core monthly measure must agree; unlisted URLs are not guessed and another month cannot fill a missing release. Paragraph/table/period/publication checks must agree. Default PCE overview is context only; default CPI collects venue terms only. Retained named releases do not prove unchanged original bytes or resolve correction policy. Annual/seasonal revision notices remain visible; missing SA provenance keeps PCE assessment unknown. Future releases are pending and source failures unavailable, never NO/fallback/settlement. The same sources, clocks and release limits survive explicit save/read/export. Saving starts no watch; this source read adds no policy or paid model. Exact PCE observation is a separate explicit default-off pilot; CPI watches remain unsupported. CPI requests identify HowSure with the public documentation URL; a source refusal stays unavailable. Fixed Check core-cpi-september-20261014-v1 retains its original official October 14 capture separately, never as a fresh source read.","JS/CLI/MCP 0.1.20 and Python 0.1.14 introduced the complete July PCE precision-example wording and August CPI em-dash wording. The July PCE monthly source keeps its forward-looking annual-update notice; it is not an update already applied. GDP guidance acknowledges a validated complete event roster even when the qualifying figure is pending or unavailable, without resolving strict upper-tail equality. Those wording fixes kept HTTP fields, flags and OpenAPI 1.14.0 unchanged; the later archive sourceVersion requires the current clients described next.","JS/CLI/MCP 0.1.23 saved recheck returns monthly_comparison for an exact original CPI/PCE monthly scope.

Raw comparison schema v4, default v1 unchanged. Compare valueComparison before/after/deltaPercentagePoints and provenance independently; current-summary to dated CPI archive can mean zero numeric delta and changed provenance while literal text is not comparable. Missing source is incomplete, reused release time no_new_observation, not unchanged/NO/fallback. PCE seasonal adjustment remains unverified; original bytes and settlement unknown, author probability unchanged. No monthly watch, new HTTP endpoint or paid model. Details /examples/README.md#exact-monthly-cpipce-changes.","JS/CLI/MCP 0.1.29, Python 0.1.21 and OpenAPI 1.20.0 support owner-selected sharing of one exact Check version with a chosen key. New private list/read calls request include_shared=true; reads keep include_corrections=true. Shared read requires exact version and returns owner_shared_unverified plus sharedAccess grantId/projectionSha256/grantedAt/expiresAt. The one-claim projection excludes private notes, title/summary, thesis, context and assessment, but preserves the explicitly previewed statement and source capture. Preserve each listed version ID; multiple grants can refer to versions of the same document. The digest is a confirmation reference, not authenticity proof. Existing SDK/CLI/MCP recheck preserves access and correction metadata even on source failure. Owner-only grants can be revoked; agents cannot grant, append, watch or read other versions. Copies already read cannot be recalled. Old clients/HTTP without include_shared preserve agent-created-only behavior. No new tool, source call, model or automatic watch is added.","JS/CLI/MCP 0.1.28, Python 0.1.20 and OpenAPI 1.19.0 request include_corrections=true on the existing private saved-version GET. The separate correctionReview binds document/version/claim/market IDs and is preserved on explicit JS/CLI/MCP rechecks, including source failure. An affected finding names a known HowSure output correction and an action; unknown or absent review is not a clean bill of health, and not_affected means no match to a finite registry only. Original versions and prior exports remain unchanged. This is delivered on read, not pushed to offline copies. The initial registry covers one exact GDP bracket warning, not all old GDP responses. No new MCP tool, source call, automatic revision, watch, message or paid model is introduced. Raw HTTP without the flag preserves its legacy shape.","JS/CLI/MCP 0.1.27, Python 0.1.19 and OpenAPI 1.18.0 add optional contract_reading.calendar.nextMeeting for the supported December Fed calendar v3 passage. Exact next-year January start/end dates retain status tentative and confirmationEstablished:false. nextMeeting.noStatementCutoff.date equals the end date; time and timeZone are null, basis is end_date_of_next_scheduled_meeting, and exceptionEstablished:false. Do not turn that date into midnight/UTC, confirmed schedule, no-statement proof or settlement. Complete selected December and next-year January rows, both footers and the shared schedule qualification are required; the shared Note's later January date is not the next meeting. Existing request flags, source budgets and old calendar readings remain unchanged. Upgrade both clients to validate the field; older packages can pass it through unchecked.","JS/CLI/MCP 0.1.26, Python 0.1.18 and OpenAPI 1.17.0 add the exact Core CPI/PCE monthly 0.6% or more template. Optional contract_reading.cpiRelease.reportedValueComparison or contract_reading.pceRelease.reportedValueComparison retains greater_than_or_equal, thresholdPercent 0.6, the reported one-decimal value or null, numeric status and qualifyingConditionEstablished:false. Exactly 0.6% is included; missing facts remain unavailable. Overall conditionAssessment stays unknown. Equality responses omit this field. No extra flag/source/watch or paid model is added. Older JS rejects these new readings; older Python does not validate the new comparison field, so upgrade both. Python binds the full question/terms, selected month/year and schedule rather than trusting derived fields.","JS/CLI/MCP 0.1.25, Python 0.1.17 and OpenAPI 1.16.0 support the exact Q4 2025 GDP Advance reschedule: the original January 29 contract date is preserved, and a retained official postponement plus schedule must corroborate the February 20 publication. Advance 1.4% remains separate from the independently indexed April 9 Third Estimate 0.5%. Only explicit GDP release reads can add the historical revision source. Earlier clients may reject this reading; install the complete new archive. No unchanged-original-bytes or settlement proof is claimed.","JS/CLI/MCP 0.1.24 and Python 0.1.16 admit exact official wording retained for July 2026 CPI and June 2026 PCE. CPI prior-month unchanged requires a zero prior core Table A figure. June PCE preserves the complete prospective annual notice and exact PIO archive notice under its declared release context. Values, month/year and release clocks stay bound; unknown wording remains unavailable. Earlier packages may reject these readings; upgrade the complete archive. HTTP/OpenAPI 1.15.0 and request/response shapes are unchanged. No paid model, automatic watch, original-release proof or settlement claim.","JS/CLI/MCP 0.1.24, Python 0.1.16 and OpenAPI 1.15.0 accept CPI observation.sourceVersion retained_archive_release alongside retained_current_summary. The existing explicit CPI release scope reads the exact selected-month archive URL listed in the retained official index; URL date, printed release date, reference month/year and core monthly narrative/Table A values must agree. Existing current-summary payloads remain valid even when their index lists an archive. Neither source form authenticates unchanged initial bytes or establishes settlement. Install the new clients for the new archive observation; old archives keep their previous coverage. No new flag, endpoint, model or automatic watch is added.","GDP boundary opt-in include_brackets=true requires include_release=true and excludes include_decision. Scope gdp_release_brackets adds the exact full event roster for at most six sources, including closed contracts and a separately indexed historical revision when supported. release.brackets preserves selected/assigned identities and unknown states; strict upper-tail equality remains unknown. Explicit GDP release allows up to five sources; no monitoring or settlement is enabled.","Local compareSourceEvidence includeRelease:true (MCP same existing tool; CLI evidence-compare --include-release true) returns v3 release_comparison rebuilt from retained sources.
