AnswerPool

Computed answers over US public data for AI agents. What is different here is the JOIN: SEC EDGAR, the Federal Register, USAspending, NIH, openFDA, CISA KEV, ClinicalTrials.gov, NWS and OpenAlex are held together, so one call returns an answer no single-source wrapper can assemble: the public companies whose filings cite a new rule, at /v1/impact/rule and /v1/impact/company; a technology's federal funding and research trajectory, at /v1/funding/signals; any name resolved to the CIK, LEI, ticker and NAICS other datasets key on, at /v1/entity/resolve.

And the forecasts are scored. Flagged SEC events and research-momentum calls are written once to an append-only prediction ledger with everything needed to resolve them later; resolution only fills in the outcome. GET /v1/evals (free) publishes the tally per method — made, pending, resolved, mean Brier score — and the reasons a number there is not yet evidence of skill.

80 of 137 endpoints are FREE with no key — every identifier lookup and glossary (ticker/CIK, SIC, NAICS, PSC, agency, NIH institute, BLS series id), the filing and rulemaking feeds, the since cursors you poll, and the macro snapshot; the derived analyses are paid, from $0.02. EVERY product also has a free static sample, one per product, listed at /v1/samples and served at /v1/samples/sec_xbrl_ratios and the like — see a real answer before paying, and over MCP call answerpool_get with sample=true for the same thing. To pay: x402 (USDC on Base, no signup — call, get 402 with the price, retry signed) or prepaid card credits from $1 (POST /v1/credits/checkout). Failed calls are never charged.

EVERY answer carries public provenance (result_id, sources, dataset and methodology versions), a refresh_after time — the next moment the source behind it can differ, so schedule the next call on it rather than on a guess — and priced next_endpoints hints, the follow-up call already written with its price. For repeat monitoring, /v1/sec/watchlist (up to 25 tickers, $0.02) and the free since feeds return a next_cursor: store it, call again, receive only what is new.

START HERE: GET /v1/catalog?q= returns just the endpoints that answer it, with price and a ready-to-call example URL, instead of reading the full list below. GET /v1/sec/resolve?q=<ticker|CIK|company name> resolves any issuer and returns the next calls to make. Both free.

Endpoints
