}Each API covers one domain. We say exactly what is covered and what isn't, so you know what you can build on before you write any code. See the full catalogue, including the APIs we plan to add.
DOL Form 5500 and 5500-SF filings by plan sponsor EIN and plan number: participants, assets, contributions, benefits paid and expenses by plan year, with sponsor name-prefix search.
IRS exempt organisations by EIN (EO BMF) with Form 990, 990-EZ and 990-PF revenue, expenses and assets from the IRS SOI extracts, the e-filed returns the IRS publishes, and name-prefix search.
Premises licences and club premises certificates from council licensing registers: premises, licensable activities, hours, status and dates, and the licence holder when it is an organisation, with the source row behind every value.
Census ACS 5-year demographics for ZCTAs and counties with margins of error, NCES public schools near a ZCTA, and comparison.
Payments English councils publish under the Local Government Transparency Code in one schema: search by council, supplier, date and amount, with supplier and council totals and the files and months loaded.
City and county capital budgets and capital improvement programmes in one schema: projects, departments, funding sources, amounts by fiscal year and status, with the source row or PDF page behind every amount.

Government data is authoritative but hard to cite: releases are revised, geographies don't line up and caveats sit in technical documentation. Olympus puts that context into the response.
Responses include a meta.coverage block and notices, e.g. that a ZCTA is not a USPS ZIP code. The coverage page lists every source, vintage and known gap.
Each record carries provenance: the upstream URL, source release, publication time, schema version and validation status. SEC values link to the EDGAR filing they were taken from.
Data is published in validated releases listed in meta.datasets. Records keep their original published_at until they change; restated SEC values are flagged with the first reported figure alongside.
