Public API

Read KYI-verified assets and embed verification badges.

The Bluprynt Public API returns the verified record behind an asset: its issuer, the wallets with authority over it, and whether each one is verified. It serves exchanges, wallets, data providers and regulators that need evidence-backed asset facts without running KYI themselves.

Base URL

https://integrations.bluprynt.com

Every route is a read-only GET. There are no write endpoints.

The interactive API reference at integrations.bluprynt.com. Click Authorize (1) to attach your key, then open any route — the Assets lookups (2) and the KYI token lookup (3) — and use Try it out.

Endpoints

Endpoint	Key needed	Returns
GET /assets	Yes	All verified assets, paged with page_size and page_number.
GET /assets/{chain}/{account_address}	Yes	One asset by chain name, such as ethereum or solana.
GET /assets/{namespace}/{reference}/{account_address}	Yes	One asset by CAIP-2 chain ID, such as eip155/1.
GET /kyi/v1/tokens	Yes	KYI verification for a token by CAIP-19, or by address with an optional chain.
GET /api/v1/badges/{credential_type}	No	A KYI or Proof of Collateral badge image.

The two /assets lookups return the same record. The CAIP form also covers chains that have no short name, such as eip155/98866 for Plume.

Authenticate

Send your API key as the raw Authorization header value. Don’t add a Bearer prefix: the API rejects it. Ask [e-mail] for a key.
