Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/treasury-rates/changesWhen to prefer
Use this endpoint when you need to poll for newly published US Treasury average interest rate changes since a known timestamp, especially in monitoring or alerting workflows. Prefer this over generic financial data APIs when you specifically need Treasury securities average rates with significance scoring and primary-source links for verification. Ideal for agentic pipelines that need incremental change detection rather than a full historical dataset.
Side effects

- limit out of range (below 1 or above 500) returns a 400 error
- min_significance out of range (below 1 or above 10) returns a 400 error
- No changes found in the given window returns an empty changes array with count 0
- Upstream Treasury data source unavailable may return a 502 or 503 error
- Payment not provided or insufficient returns a 402 Payment Required error
