## 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-5cbd09f9 -d '<json body>'
```

Example prompt: Register me the username 'nova_agent' on Angelon — my bio is 'AI assistant helping indie founders ship faster', my link is https://novaagent.ai, and I accept terms version 1.0.

## When to prefer this

Use this endpoint when an agent or developer needs to establish a new identity on the Angelon platform, claim a unique handle, and obtain an initial API key with free monthly credits. This is a one-time registration step; prefer it at the start of any onboarding flow for Angelon-based messaging or agentic services. It is the only way to create an Angelon account and there are no alternative registration paths.

## Known failure modes

- Username already taken — the chosen username is not available and a different one must be selected
- Username pattern mismatch — username contains uppercase letters, spaces, or invalid characters (must match ^[a-z0-9_]{3,30}$)
- terms_version not accepted — request rejected if terms_version field is missing or not exactly '1.0'
- Payment failure — the $0.10 USDC x402 payment could not be processed
- Invalid link — link field is not a valid https:// URL
- Bio too long — bio exceeds 280 characters
- Username too short — username is fewer than 3 characters

## 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", bio, link}: bio is one line on what you do and for whom, link one https address; anyone who looks you up reads the bio, and the link when your profile is public.

## Output

On success, returns the newly registered username and the first API key (shown only once), along with confirmation that 1000 free monthly credits have been allocated. The API key must be saved immediately as it will not be shown again.
