# ChainWard Set-and-Earn Week One Dataset Check

> ChainWard Set-and-Earn Week One Dataset Check is a paid API for AI agents from api.chainward.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-12).

Checks whether a given wallet address appears in the 'Set and Earn week one' dataset (wallets that hired an agent Oct 1–8), returning its tier, group fields, and listing verdict as JSON.

## 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 chainward-set-and-earn-week-one-dataset-check-aba596e0
```

Example prompt: Can you check if wallet 0x00048bfe5972a462c5ca6adc2e373f2b49c4874d is listed in ChainWard's Set and Earn week one dataset — the one covering wallets that hired an agent between Oct 1 and Oct 8 — and tell me its tier and any group fields?

## When to prefer this

Use this endpoint specifically when you need to verify whether a wallet participated in the 'Set and Earn week one' incentive window (Oct 1–8) and want structured tier/group metadata about that participation. Prefer it over generic wallet screening when the use case is incentive eligibility, reward distribution, or program audit for this specific dataset window. For broader risk screening or OFAC sanctions checks, use the sibling ChainWard sanctions or general check endpoints instead.

## Known failure modes

- Invalid or malformed address (not matching 0x + 40 hex chars) returns a validation error
- Wallet not found in dataset returns verdict 'not listed' with no matches array
- Payment failure or missing x402 payment header returns 402 Payment Required
- Network timeout or service unavailability returns 5xx error
- Address in correct format but on unsupported chain may return not listed with no tier info

## How this service works

Paste any Base or BNB Chain address before you pay or hire it. ChainWard tells you Pay or Hold, and why, from the wallet’s on-chain history. Free.

## Output

Returns a JSON object with a 'verdict' field ('listed' or 'not listed'), a 'reason' string explaining the result, the dataset's time window as 'limit', and — if listed — a 'matches' array containing the wallet's tier (e.g. A1), chain, cluster, first_seen date, fees_paid_usd, jobs_as_buyer, jobs_as_seller, and exchange_withdrawal_burst. Also includes the dataset slug, as_of date, and a link to the full dataset file.
