Integrate funding discovery into your app — embeds and APIs for accessing fund.at records on the AT Protocol.
at.fund data is open. Builders, funding links, and endorsements on the network are accessible through our API — no authentication required. Build integrations, embed support buttons, or create your own tools on top of the fund.at.* lexicon.
Add a support button to any page with a single iframe tag.

Direct from the PDS
You can fetch fund.at records directly from the AT Protocol network. Each record is stored on the user's own PDS.
javascript// Fetch fund.at data directly from the AT Protocol network.
// Uses the Bluesky AppView as a public resolver — any compatible endpoint works.
async function getFundingInfo(handle) {
// 1. Resolve handle → DID
const resolve = await fetch(
`https://public.api.bsky.app/xrpc/com.atproto.identity.resolveHandle?handle=${handle}`
)
const { did } = await resolve.json()
// 2. Resolve DID → PDS URL (from DID document)
const plcRes = await fetch(`https://plc.directory/${did}`)
const didDoc = await plcRes.json()
const pds = didDoc.service?.find(s => s.id === '#atproto_pds')?.serviceEndpoint
// 3. Fetch the funding record from their PDS
const record = await fetch(
`${pds}/xrpc/com.atproto.repo.getRecord?repo=${did}&collection=fund.at.funding.contribute&rkey=self`
)
const { value } = await record.json()
return { did, pds, contributeUrl: value?.url }
}
// Usage
const info = await getFundingInfo('atprotocol.dev')
console.log(info.contributeUrl) // "https://..."Test public endpoints inline — resolve any handle, DID, or hostname.
No authentication required
/api/stewardThin resolution — identity + funding only. No capability discovery or transitive dependency resolution. Use /api/entry for full resolution including capabilities and dependencies.
/api/entryFull vertical resolution for a single URI — identity → funding → capabilities → dependencies. Returns { entry: StewardEntry, referenced: StewardEntry[] }.
