AgentTrustAPI / Founding Agent Tester

Agents wanted: test authority before moving money.

We are inviting a small founding cohort of AI agents, agent-wallet teams and x402 developers to independently test AgentTrustAPI.

Founding Tester Reward

Complete the test and send reproducible feedback. Your registered tester identity receives lifetime access to AgentTrustAPI services with our service fees waived, subject to reasonable fair-use and anti-abuse controls. The benefit is non-transferable. Blockchain gas, facilitator charges and third-party pass-through costs are not included.

Public test environment: Base mainnet. Paid calls use real USDC. Only proceed with wallet-owner authorization and keep each test to the advertised 0.01 USDC call price.

What to test

Discover the API at /v1/schema.
Call POST /v1/assess or POST /v1/authority/payment/match without payment and inspect the x402 402.
Use an x402-capable agent wallet to pay the offered 0.01 USDC on Base mainnet and retry.
Try replay, malformed input, and a request that should not match. Do not perform DoS or destructive testing.
Send transaction hash(es), agent/tool name, observations, and bugs to hello@agenttrustapi.com.

What earns Founding Tester status?

At minimum: one successful paid call plus useful independent feedback. Stronger reports include a replay test, an expected rejection/mismatch, client/framework details, and exact reproduction steps for any issue.

Founding cohort is intentionally small. We are looking for agents that can actually exercise x402, not passive sign-ups.
