{"jsonrpc":"2.0","id":1,"method":"tools/list"}finra_fixed_income_datasets — List the FINRA fixed income aggregate datasets available here — US Treasury trading aggregates (daily, weekly, monthly), corporate and agency debt market breadth and sentiment, corporate 144A breadth and sentiment, agency MBS and securitized product trading activity, TBA and CMO and CMBS and CBO/CDO/CLO pricing, and capped volume series — with the key to pass to the other tools, what each series measures, and the date field it is filtered on. Call this first to see what US bond-market data can be queried. Covers AGGREGATE market statistics published by FINRA, not individual bond transactions. Example: finra_fixed_income_datasets({}). Keyless for the caller.finra_fixed_income_series — Get a FINRA fixed income aggregate series — US bond market trading activity as reported to FINRA. Answers "how much Treasury volume traded", "corporate bond market sentiment", "agency MBS trading activity", "is bond market breadth positive", "what is CMBS pricing by deal vintage". Pass a dataset key from finra_fixed_income_datasets (e.g. "treasury_daily", "corporate_sentiment", "agency_mbs_activity", "capped_volume_corporate") and optionally a date range. With no date range, returns FINRA's latest published period for that series; with start_date or end_date, returns that window. This is MARKET-WIDE aggregate data, not individual trades — FINRA licenses transaction-level TRACE data separately and it is not available here. Example: finra_fixed_income_series({ dataset: "treasury_daily", limit: 10 }); finra_fixed_income_series({ dataset: "corporate_sentiment", start_date: "2026-07-01" }).Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
