Mavenly Grant Data API
Clean grant data, wherever your product lives
One REST and webhook service for thousands of federal and state funding opportunities — normalized, tagged and enriched, so your team never writes another Grants.gov parser.
01 — Who builds on it
University sponsored research offices
Feed curated federal and state calls into faculty intranets and investigator matching engines.
Fiscal sponsors and intermediaries
Power branded grant-discovery portals for every sponsored project in your network.
Nonprofit vertical SaaS
Embed live grant discovery inside donor CRM, volunteer or fund-accounting products.
Philanthropic and impact advisors
Monitor agency funding shifts and regional streams for strategic client work.
02 — Raw feeds vs Mavenly
03 — The response
Predictable JSON, versioned schema
Every opportunity carries the same shape regardless of whether it came from Grants.gov, SAM.gov, NSF or the Federal Register. Award floors and ceilings are numeric, dates are ISO 8601, and eligibility is parsed into a readable summary plus a geographic scope.
- OpenAPI 3.1 spec you can generate clients from
- HMAC-signed webhooks for new and amended notices
- Per-key metering, rate limits and usage reporting
