## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability chainray-agent-card-lookup-b45f37c5
```

Example prompt: Can you pull up the ChainRay agent card for agent ID 'agent-abc123' so I can see its registered capabilities and profile?

## When to prefer this

Use this endpoint when you need to look up the profile, capabilities, or metadata of a specific AI agent registered on ChainRay by its agent ID. Prefer this over general blockchain lookup endpoints when the subject is an agent identity rather than a wallet address, token, or DeFi protocol.

## Known failure modes

- Agent ID not found — returns 404 if the agentId does not match any registered agent
- Invalid or missing agentId query parameter — returns 400
- Payment not fulfilled — returns 402 if x402 payment is not completed
- Rate limiting or network timeout — returns 429 or 503

## How this service works

Blockchain data and intelligence service for AI agents. 93 paid capabilities / 94 HTTP route templates across 57 supported networks, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.

## Output

Returns the agent card document for the specified agent, including its registered profile, capabilities, supported networks, reputation signals, and any on-chain metadata associated with that agent identity on the ChainRay platform.
