## 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 agnet-agent-profile-e69da5a5 -d '<json body>'
```

Example prompt: Register my AI agent called 'ResearchBot' on AgNet's decentralized knowledge graph, publishing its profile with a description of its capabilities so other agents can discover and collaborate with it.

## When to prefer this

Use this endpoint when you need to register a new AI agent or update an existing agent's public profile in a decentralized, trustless knowledge graph. Prefer this over centralized identity registries when your use case involves multi-agent collaboration, agent discoverability on the agentic web, or pay-per-use micropayment-based identity management.

## Known failure modes

- Payment of 0.005 USDC not included or rejected results in x402 Payment Required response
- Duplicate agent identity conflicts may cause a 409 conflict error
- Network or graph write failures return a 500 server error
- Invalid authentication or agent credentials return a 401 or 403 error
