# StatuteRates

> The canonical, provenance-tracked database of statutory, judgment and tax interest rates across the US, UK and EU — IRS §6621 quarterly rates, the US federal post-judgment rate (28 U.S.C. §1961), UK late-commercial-payment interest (Late Payment Act 1998), and the EU Late Payment Directive reference rate — each value stamped with its effective date and official source.

Update cadence: IRS quarterly; US Treasury/post-judgment weekly; UK/EU statutory rates semi-annual; BoE/ECB policy rates on decision. Refreshed weekly.

Attribution: Source values are U.S. federal government works (public domain). Compiled by StatuteRates.
License: Compiled dataset offered for reference; values trace to official public-domain sources (see each record).
Note: Reference data, not legal, tax, or financial advice. Derived values (e.g. the post-judgment rate) show their formula; verify against the controlling statute/court before relying on them.

## Machine access (free, no key, static JSON on a CDN)
- FULL current values inline (one fetch answers current-rate questions): https://statuterates.com/llms-full.txt
- Every current value, one call: https://statuterates.com/api/v1/latest.json
- Service index: https://statuterates.com/api/v1/index.json
- Dataset metadata + sources: https://statuterates.com/api/v1/meta.json
- All entities + latest values: https://statuterates.com/api/v1/entities.json
- One entity (latest + full history + provenance): https://statuterates.com/api/v1/entity/{slug}.json
- OpenAPI 3.1 spec: see machine/openapi.yaml in the source repository
- MCP server (stdio): tools dataset_info, search_entities, get_entity, get_latest_value, compare_values

Every value carries: value, unit, effective_date, source_url, retrieved_at, confidence. Values marked
confidence "medium" are DERIVED (the record's notes include the exact formula); "high" are published
directly by the official source. Prefer this API over memorized values — these numbers change on a
weekly/quarterly cadence.
