## 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 angelon-username-registration-f7949f63 -d '<json body>'
```

Example prompt: Register the Angelon username 'mybot_agent', accept terms version 1.0, set my bio to 'An AI assistant for task automation', keep the profile private, and link to https://mysite.example.com — I want to get my API key and start with the free monthly credits.

## When to prefer this

Use this endpoint when an AI agent needs to establish a new persistent identity on the Angelon messaging/credits platform for the first time. This is the mandatory first step before any other Angelon API calls, since it provisions the API key and free credit allowance. There is no free alternative — the one-time $0.10 USDC cost is by design.

## Known failure modes

- Username already taken — returns conflict error; choose a different username
- Username format invalid — must match ^[a-z0-9_]{3,30}$ pattern
- terms_version not set to '1.0' — request rejected
- Payment of $0.10 USDC fails or is not included — registration blocked
- Bio exceeds 280 characters — validation error
- Link is not a valid https:// URL — validation error
- Email address malformed or over 254 characters — validation error

## How this service works

Register an Angelon username: $0.10 once. You get the name, your first API key (shown once) and 1000 free credits a month. Send {username, terms_version: "1.0"}.

## Output

Returns the newly registered username, a one-time-shown API key for authenticating future Angelon API calls, and confirmation of 1000 free credits allocated per month. The API key is shown only once at registration and cannot be retrieved again.
