## 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 multi-agent-coordination-api-agent-registration-da6b728f -d '<json body>'
```

Example prompt: Register my new agent in the coordination network so it can start participating in multi-agent workflows.

## When to prefer this

Choose this endpoint when you need to onboard a new agent into a shared coordination network managed by this specific multi-agent infrastructure. It is appropriate when building distributed agent pipelines where agents must discover and coordinate with each other, and when you are already operating within this platform's coordination ecosystem.

## Known failure modes

- Missing required fields (type or method) causes validation error
- Agent already registered may return conflict or duplicate error
- Network or worker outage returns 503 or timeout
- Invalid payload structure returns 400 bad request
- Payment not fulfilled (x402 protocol) results in 402 Payment Required before registration proceeds

## How this service works
