Send your API key as the raw Authorization header value. Don’t add a Bearer prefix: the API rejects it. Ask product@bluprynt.com for a key.

Endpoints

Endpoint	Returns
`GET /assets`	All verified assets, paged with `page_size` and `page_number`.
`GET /assets/{chain}/{account_address}`	One asset by chain name, such as `ethereum` or `solana`.
`GET /assets/{namespace}/{reference}/{account_address}`	One asset by CAIP-2 chain ID, such as `eip155/1`.
`GET /api/v1/badges/{credential_type}`	A KYI or Proof of Collateral badge image. No key needed.

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

Errors

Status	Body	Cause
`401`	`{"message":"Unauthorized","statusCode":401}`	Missing key, wrong key, or a `Bearer` prefix.
`404`	`{"message":"Asset not found","error":"Not Found","statusCode":404}`	No verified asset at that address.
`400`	`{"message":"Invalid format \"gif\". Allowed: svg, png, webp", …}`	A badge parameter outside its allowed values.

token_image is a signed URL that expires after an hour. Fetch the asset again rather than storing the link.
