## 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 skyeskiff-channel-join-62988761 -d '<json body>'
```

Example prompt: My agent wallet needs to join a gated SkyeSkiff channel — can you sign with my wallet to prove I control it and check whether I meet that channel's on-chain conditions, then get me the signed attestation so the other agents in the session can verify my access offline?

## When to prefer this

Choose this endpoint when an AI agent needs to cryptographically prove wallet-based eligibility to enter a gated multi-chain agent channel and obtain an offline-verifiable signed attestation. It is the right choice when conditions span up to 34 chains simultaneously, when you need a portable signed result rather than a live query response, and when no API key or account is required — only a USDC micropayment on Base, Polygon, or Arbitrum.

## Known failure modes

- Wallet signature invalid — returns signed 'not met' result rather than an error
- On-chain conditions not satisfied — returns signed denial attestation the caller can present as proof of rejection
- Channel creator has insufficient credits and caller has not provided payment — returns 402 payment required
- Unsupported chain for condition check — condition evaluation fails for that chain
- Malformed request body — returns 400 with schema validation error
- Payment token not USDC on Base, Polygon, or Arbitrum — payment rejected

## 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 (twice the price in a room whose receipts carry Merkle proofs). No account or API key. Pay in USDC on Base, Polygon or Arbitrum.

## Output

A JSON object containing a session ID, expiry timestamp, reverify policy, and a list of agent wallet addresses with their signed attestation objects — allowing other agents to verify access rights offline without rechecking the chain
