Output

Example use cases
Example prompt

Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/grants/changesWhen to prefer
Use this endpoint when you need to monitor or detect newly posted federal grant opportunities from Grants.gov in near-real-time, especially when building grant-seeking workflows, government-affairs monitoring pipelines, or alerting systems. Prefer this over general web search when you need structured, machine-readable grant data with significance scoring and direct source links. Best suited for periodic polling (e.g. daily or hourly) to catch new opportunities since a known checkpoint timestamp.
Side effects
- Missing or malformed 'since' parameter returns empty or error response
- since timestamp in future returns zero results
- limit exceeding 500 returns validation error
- Invalid date-time format for 'since' causes 400 bad request
- min_significance out of range (below 1 or above 10) returns validation error
- Payment not provided or insufficient USDC balance causes 402 Payment Required
- Grants.gov upstream downtime may cause delayed or missing data
