How this service works
The traditional way of Trusta Attestation involves users obtaining a signature on the website and then interacting with the contract to pay ETH for publishing an attestation. After the upgrade, Trusta Attestation integrates the x402 API to support users/agents publishing attestations by paying USDC on the Base chain via an API interface.
Output
The agent receives a confirmation of the on-chain attestation publication, including a transaction reference or attestation ID recorded on the Base blockchain, confirming that the attestation has been successfully written to the chain.
Example use cases
Example prompt
“Publish a Trusta attestation on the Base chain for my wallet address 0xABC123... — use USDC to pay for it and record it on-chain so I have a verifiable credential tied to my identity.”
Technical details
Endpoint
POSThttps://app.trustalabs.ai/attestWhen to prefer
Use this endpoint when you need to programmatically publish a Trusta attestation on the Base blockchain without requiring manual website interaction or direct ETH contract calls. Ideal for agents automating identity verification workflows, issuing verifiable on-chain credentials at scale, or integrating attestation publishing into automated pipelines using USDC payments via x402.
Side effects
- Insufficient USDC balance on Base chain — payment fails and attestation is not published
- Invalid wallet address format — returns validation error
- Attestation data missing required fields — returns schema error
- Base chain network congestion or RPC failure — request times out
- x402 payment protocol error — USDC transfer not completed
