OFR Short-Term Funding Monitor API — data.financialresearch.gov/v1, keyless,
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
The Office of Financial Research (US Treasury) Short-Term Funding Monitor API — collateral- and tenor-level US repo market rates/volumes (DVP, GCF, tri-party) and money-market-fund balance-sheet composition, neither of which FRED or the NY Fed Desk's own release carries.
Part of Pipeworx — an MCP gateway connecting AI agents to 1683+ live data sources.
Tools
ofr_repo_rates(collateral, tenor, measure, vintage, start_date, end_date, limit)— repo rates or volumes for one collateral segment (dvp/gcf/tri/triexfed) x tenor (overnight/term bucket/collateral-type split) x measure (rate/volume/outstanding).ofr_mmf_holdings(category, start_date, end_date, limit)— monthly money-market-fund investment composition (repo by collateral/counterparty type, outright Treasuries/agencies, bank-related assets).ofr_search_funding_series(query, dataset, limit)— name/mnemonic lookup across the full 206-series repo+mmf catalog (OFR has no live search endpoint).ofr_funding_anomaly(mnemonic OR collateral/tenor/measure/vintage, window_days)— compares the latest observation to a trailing window and reports delta + z-score, stating the exact window used.

Data sources
https://data.financialresearch.gov/v1/series/timeseries?mnemonic=...— the only live per-query route. Returns a bare[[date, value], ...]array for one mnemonic. Used by all four tools for every actual data point returned.https://data.financialresearch.gov/v1/series/dataset?dataset=repoand?dataset=mmf— bulk metadata+data dump (~9MB gzip'd, ~450KB for mmf) used ONCE (2026-09-23) to generatesrc/catalog.ts(mnemonic → human name → start date → frequency). Never called at request time; too large to fetch per call in a Worker, and would be a bulk mirror if it were. The actual VALUES this pack returns always come from thetimeseriesendpoint above, live, pe
