Get started with RFP API

Overview

The RFP (request for proposal) API gives you live access to open grant opportunities that you can surface directly inside your own product.

Show your users a live feed of open RFP opportunities, filtered by subject area, population served, and geographic area.
Return open opportunities for a specific funder, with no search workflow to build.
Keep your product current automatically. Every response reflects the current state of Candid's open opportunity data, so there is no manual refresh step.
Build with AI-native tooling. The API is consumable through Model Context Protocol (MCP) enabled tools, so an AI assistant can recommend relevant RFPs to your users in real time.

/rfp/v1/search
Search open RFP opportunities using free text plus filters for subject area, population served, and geographic area. Results can be paginated and sorted by organization name or deadline.
/rfp/v1/profile
Return open RFP opportunities offered by a funder, supplied as an EIN or Candid entity ID. Use this when you already know which funder you're interested in and want to view their open opportunities.
/rfp/v1/opportunity
Get all the details for a specific open RFP opportunity.

Full parameter and response details for each endpoint are documented on their individual reference pages.

For nonprofit-tech platforms:
Surface a live RFP feed to your nonprofit customers without maintaining your own funding dataset.
For AI-native fundraising apps:
Call the API directly, or through an MCP-enabled tool, so an AI assistant can recommend relevant RFPs to fundraisers as they work.
For nonprofits with in-house developer or data teams:
Pull RFPs matched against your organization's priority subject areas and regions.
For prospect-research and donor-intelligence vendors:
Enrich your product with an always-current RFP feed for your nonprofit customers.

Each opportunity includes the following core fields, where available:
