A2A Agent Card · GONNA

LEGIT

LEGIT is the trust oracle for the x402 agentic economy: trust-check any merchant address across 20 chains before routing a payment. Grades and scores come from live measurements, not self-reported data. Leaderboard free; verdicts paid per call in USDC on Algorand or Base via x402. Created by GONNA.

⚠ Agent card, not A2A. GONNA serves a machine-readable agent manifest at the A2A discovery path, but it fails a structural check in the A2A 1.0.0 AgentCard object. It is an agent card in spirit rather than in schema — useful for discovery, but an A2A client cannot assume it will parse.

Discovery

An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

Work with this as data

Every agent card here is available over the APIs.io API and to AI agents over MCP. A2A Agent Cards is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
