The Treasury's official quarterly 'Reporting Rates of Exchange' for a country's currency, as required for federal financial reporting. Called as GET /v1/treasury/reporting-rate, it takes country, currency, asOf and returns found, exchangeRate, recordDate, fiscalQuarter. Distinct from the neighbouring services in this domain by: official, rates, required, financial. Federal grantees, contractors and anyone filing in USD must convert at the Treasury rate rather than a market rate, and using the wrong one makes the filing wrong. Reading this schema and dry-running the call are free and need no wallet; a real call costs $0.003, paid in USDC on Base over x402.

Why call it rather than answer from memory
Federal grantees, contractors and anyone filing in USD must convert at the Treasury rate rather than a market rate, and using the wrong one makes the filing wrong.

you sign an authorization, and a facilitator settles it — you never send a
transaction and never pay gas. Before it spends anything, the client checks its
own hash against the gateway and refuses rather than sign with logic the
gateway has moved past:

Base — no account, no API key, and no ETH, because the payer signs off-chain and
the facilitator broadcasts and pays the gas.
Writing your own client instead of using this one? and
on npm, and the skill records the two things that cost
real debugging time: the challenge is in a response header rather than the body,
and it must be re-signed from the exact request being retried.
