How this service works
OFR Short-term Funding Monitor daily series from the US Office of Financial Research, for one mnemonic (default FNYR-SOFR-A, the SOFR rate in percent): the latest N observations.
Output
Returns a JSON object containing an array of dated rate observations (each with a date string and numeric value), the OFR source URL, the series mnemonic queried, and a checkedAt timestamp indicating when the data was fetched.
Example use cases
Daily SOFR rate dashboard refresh
“Fetch the 10 most recent SOFR (FNYR-SOFR-A) observations from the OFR funding monitor so I can update my rates dashboard.”
Benchmark rate trend analysis
“Get the last 100 daily readings for the FNYR-SOFR-A series from the OFR short-term funding monitor — I want to chart how the rate has moved over the past few months.”
Automated rate alert check
“Pull the latest SOFR rate from the OFR short-term funding monitor and tell me if it has moved by more than 5 basis points compared to the previous observation.”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/finance/ofr-short-term-funding-monitor?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official U.S. short-term funding rate data (e.g. SOFR, EFFR, or other OFR-tracked series) sourced directly from the Office of Financial Research. Prefer this over cryptocurrency or DeFi rate endpoints when dealing with regulated benchmark rates used in loan pricing, derivatives, or compliance contexts. Ideal for agents that need no-signup, pay-per-call access to authoritative macroeconomic rate data without maintaining API credentials.
Side effects
- Invalid or unrecognized mnemonic returns empty or error response
- Requesting more than 100 observations may be rejected or clamped
- OFR upstream data unavailable causes fetch failure
- Rate series not yet updated for the current date returns last available reading only
- Malformed query parameter types may result in a 400 error
