# SkyeSkiff Session Re-verification

> SkyeSkiff Session Re-verification is a paid API for AI agents from skyeskiff.skyemeta.com, paid per call via x402, $0.15/call, status unknown (last checked 2026-10-18).

Re-checks all member wallets in an active agent session against current on-chain conditions, removing ineligible members and re-attesting eligible ones with fresh signed results.

## 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-session-re-verification-82925e40 -d '<json body>'
```

Example prompt: Re-verify everyone currently in our agent session and remove any wallets that no longer meet the channel's on-chain conditions — give me fresh signed attestations for whoever still qualifies.

## When to prefer this

Use this endpoint when you need to continuously enforce on-chain access control in a running multi-agent session — particularly when time has passed since the session was opened, market conditions may have changed token balances, or NFT ownership may have shifted. Prefer this over a one-time join check when the session is long-lived or involves sensitive negotiations. If you only need to onboard a new member, use the single-wallet join endpoint instead.

## Known failure modes

- Session not found or expired — returns error indicating invalid session ID
- On-chain RPC failure — cannot read current chain state, returns connectivity error
- No members pass re-verification — returns empty agents array with valid:false
- Payment insufficient or rejected — USDC payment on Base/Polygon/Arbitrum not accepted, call fails
- Malformed request body — missing required fields returns 400-level error
- Chain not supported — if target chain is not Base, Polygon, or Arbitrum, request fails

## How this service works

Check that everyone in an agent session still qualifies, right now. Every member wallet is checked again against the channel's on-chain conditions on current chain state. Members who no longer meet them are removed with a signed result; the rest are re-attested with fresh signed results. Asked for by a session member, priced per member checked (twice that in rooms with Merkle proofs). No account or API key. Pay in USDC on Base, Polygon or Arbitrum.

## Output

Returns a JSON object indicating overall validity, a list of agent wallets that passed re-verification each with a fresh signed attestation object, and the reverify policy applied (e.g. 'members'). Members who no longer meet on-chain conditions are excluded from the attested list.
