Live macro and rates data for finance agents.
Your model's training is months stale on the rate environment. Call interest_rates, treasury_yields, and global_macro and your agent gets current reported SOFR, Fed funds, Treasury-curve, and World Bank country indicators, each signed and carrying its source and reported observation time.
The call
One keyless POST returns US benchmark money-market rates (EFFR, SOFR, OBFR), the Treasury yield curve, and World Bank macro indicators, each with its own source URL, observed-at date, and Ed25519 signature:

# interest_rates -> EFFR/SOFR/OBFR/TGCR/BGCR (NY Fed reference rates)
# treasury_yields -> the Treasury constant-maturity curve
# global_macro {country:"all"} -> World Bank country indicators
# china_data -> China macro seriesWhy live data
A finance agent that reasons about the rate environment from a frozen training cutoff will be wrong about where SOFR and the curve sit today. These four feeds (interest_rates, treasury_yields, global_macro, china_data) pull from primary sources like the NY Fed and World Bank, and each datapoint carries its source URL, the date it was observed, and a freshness state so the agent can cite it and you can see how old it is. The Ed25519 signature establishes integrity and attribution for the record bytes; it does not independently prove time, truth, accuracy, or safety. These are macro and rate series, not market prices; there is no live crypto, metal, or stock price conversion here.
Use it for
- Ground a finance agent's answer in today's SOFR, Fed funds, and the Treasury curve instead of stale training data
- Pull World Bank macro indicators per country for a research or analyst agent
- Stamp every rate your agent quotes with a citeable source URL and observed-at date
- Pass a signed macro snapshot downstream so an auditor can verify its bytes and inspect its reported observation time
FAQ
Do these feeds give live market prices for bonds, crypto, or stocks?
No. This page covers macro and rate series only: benchmark money-market rates (EFFR, SOFR), the Treasury yield curve, and World Bank macro indicators. Live crypto, metal, and stock price conversion is paused and not offered here.
Do I need an API key?
No. POST to https://dynamicfeed.ai/v1/batch or point an MCP client at https://dynamicfeed.ai/mcp. Both are keyless and free for fair use.
What does the Ed25519 signature actually prove?
It establishes integrity and attribution under the published key, so altered bytes fail verification. It does not independently prove time, truth, accuracy, or safety. The source URL and observed-at value let you judge provenance and freshness yourself.
