## How to call it through Zero

```sh
zero fetch --capability coco-agent-tools-yaml-endpoint-028539c0
```

Example prompt: Can you fetch the YAML tool definitions from Zach Riehn's CoCo lab agent endpoint so I can see what tools are available for integration?

## When to prefer this

Choose this endpoint when you need to discover or retrieve the tool manifest for the CoCo AI agent lab in machine-readable YAML or JSON format, especially when integrating with Zach Riehn's CoCo experiments or building an agent that needs to call CoCo tools programmatically.

## Known failure modes

- Missing required query parameters may result in incomplete or empty tool listings
- Invalid 'to' or 'text' query param values may produce an error response or default output
- Service may return a 402 Payment Required if x402 micropayment is not included
- Endpoint may be unavailable or return 500 if the CoCo lab server is down
- Response may be JSON instead of YAML depending on Accept headers or server state

## How this service works

Zach Riehn's lab: an about-me and portfolio, a news desk, The Atelier for AI experiments, Launch Lab for XRP research, and Fracture for games.

## Output

Returns a JSON or YAML object describing the available agent tools, their names, parameters, and usage — structured as a tool manifest that an AI agent can parse and use for integration.
