## 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 genesis-agent-tools-agent-card-validate-65919158 -d '<json body>'
```

Example prompt: Can you validate this agent card object I've built and tell me whether it's valid and what issues it has: {card: {...}}?

## When to prefer this

Choose this endpoint when you need to programmatically validate an agent card object before publishing, registering, or deploying an agent — especially in MCP or x402 ecosystems. It is purpose-built for agent infrastructure tooling rather than generic JSON schema validators.

## Known failure modes

- Missing required 'card' field returns a validation error
- Malformed card object may return findings without a clear valid/invalid determination
- Payment failure (402) if x402 USDC payment on Base is not provided
- Empty or null card object may return invalid with generic findings
- Network timeout on the Cloudflare Worker edge

## How this service works

Pay-per-call x402 APIs for autonomous agents on Base USDC: API compatibility analysis, bounded HTTP/JSON workflows, URL evidence analysis, crypto price consensus, and agent/MCP readiness checks.

## Output

Returns a JSON object with a 'valid' boolean indicating whether the agent card passed validation, and a 'findings' array listing specific issues, warnings, or compliance notes discovered during analysis.
