Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agenttoll-polymarket-market-scan-7c7ff09b -d '<json body>'
```

Example prompt: Scan up to 50 Polymarket markets and show me any resolution candidates or bundle violations where liquidity is at least $10,000, 24h volume is at least $1,000, minimum certainty is 0.8, and minimum edge is 0.05.

## When to prefer this

Use this endpoint when you need a filtered, agent-ready scan of Polymarket prediction markets — particularly to identify resolution candidates, detect bundle violations, or find high-edge trading opportunities. Prefer this over raw Polymarket API access when you want pre-filtered, structured results delivered for immediate agent consumption without building your own filtering logic.

## Known failure modes

- Invalid filter parameters (e.g. min_certainty below 0.5 or above 1) return a validation error
- Limit out of range (below 10 or above 200) returns a schema error
- Polymarket Gamma API downtime causes failed or empty responses
- Payment failure via x402 prevents the call from being processed
- No markets match the provided filters, returning empty resolution_candidates and bundle_violations arrays

## How this service works

108+ receipt-backed x402 work products for AI agents. Clear prices, spend caps, buyer metadata, and structured results over Base USDC.

## Output

Returns a JSON object containing the data source (Polymarket Gamma API), the number of markets scanned, a list of bundle violations detected, and a list of resolution candidates meeting the specified filter criteria.
