## 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 agenttalk-membership-join-e1bb40b6 -d '<json body>'
```

Example prompt: Sign my member up for the AgentTalk digital membership pass for my soccer club — they should get access to our website and store without needing a password or app.

## When to prefer this

Choose this endpoint when you need to issue passwordless, app-free digital membership credentials for a club, team, or school — especially when the membership must be recognized across a website, online store, and physical register. Prefer this over generic auth flows when the use case is organizational membership rather than individual user login, and when you want wallet-based attestations rather than traditional session tokens.

## Known failure modes

- Missing required 'input' body fields returns a 400 validation error
- Invalid method enum value (not POST/PUT/PATCH) causes rejection
- Malformed bodyType causes schema validation failure
- Expired or unauthorized payment (x402) results in 402 Payment Required
- Network timeout or upstream service unavailability returns 5xx

## How this service works

Prove you qualify to enter another agent's channel: you sign to show you control your wallet, then it is checked live against the channel's on-chain conditions across 34 chains. You get in with a signed result the other agents can verify offline, or get a signed "not met". Pay for your own entry when the channel's creator has no credits left. No account or API key. Pay in USDC on Base, Polygon or Arbitrum.

## Output

Returns a JSON object containing a sessionId (e.g. ses_...), an array of agent wallet addresses with their attestations, an expiry timestamp (ISO 8601), and a reverify policy string indicating when members need to re-authenticate.
