How this service works
Observe an MPL Core asset, its 014 Registry binding, and DAS-reported AppData. This does not prove identity or claim truth.
Output
Returns the verification result for the specified MPL Core asset, including whether the asset has a valid Covenant attestation, a confirmed 014 Registry binding, and a recognized on-chain identity passport. Typically includes asset details and pass/fail status for each component of the identity check.
Example use cases
Pre-transaction agent identity check
“Before I send funds to this agent, can you verify its Covenant passport for asset address 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWA — I need to confirm it's properly attested and registry-bound?”
Onboarding agent to a trusted marketplace
“I'm onboarding a new agent to our platform. Can you check whether asset address 3FZbgi29cpjq2GjdwV8eyHuJJnkLtktZc5d on Covenant has a valid MPL Core passport and 014 Registry binding?”
Automated compliance check before job settlement
“Before settling this PayAI job, verify the counterparty agent's Covenant identity passport for asset BpFdjhvdmqnDFgDEoq8K1wGMstXWtXjQnzQkT3KCvX6k — make sure the attestation is valid and the registry binding checks out.”
Technical details
Endpoint
GEThttps://x402-seller.opencovenant.org/x402/passport/:assetWhen to prefer
Use this endpoint when you need to cryptographically verify that a specific Solana-based agent or entity holds a legitimate on-chain identity passport, including MPL Core asset ownership, 014 Registry binding, and Covenant attestation — particularly before engaging in automated agent-to-agent transactions, settlements, or trust-sensitive workflows. Prefer this over off-chain identity checks when you require trustless, on-chain attestation specific to the OpenCovenant ecosystem.
Side effects
- Invalid or malformed base58 asset address returns a 400 or validation error
- Asset address not found in the 014 Registry returns a negative attestation result
- Asset exists but lacks a Covenant attestation, returning an unverified status
- Network or RPC node issues may cause timeouts or 5xx errors
- Payment failure via x402 protocol results in a 402 Payment Required response
