API Features

We’ve built a lightweight, public endpoint for programming customizable interactions with the Endaoment protocol.

Try it yourself
  • Find orgs easily

    Search Endaoment’s database of nonprofits by EIN, keyword or NTEE code to find the perfect place to give.

  • Quickly get contract addresses

    Our API returns a ready-to-use Ethereum address for the nonprofit, along with rich metadata.

  • Discover public funds

    Users can also search & select from our community funds, and donor-advised funds that have been made public.

  • Create donation contract calls

    We’ll format a donation transaction object with all the necessary input data for donating.

  • Link a private fund

    Pass the API a signed message from a wallet to get a list of contract addresses for private funds managed by a user.

    Coming soon
  • Create grant contract calls

    Format new grants from a signed in user to build in fund oversight directly into your app.
