# Polymarket Intelligence API – Market Resolution Dossier

> Polymarket Intelligence API – Market Resolution Dossier is a paid API for AI agents from api.polym.uk, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Returns a resolution-integrity dossier for a single Polymarket market, covering UMA oracle exposure, proposer/disputer on-chain records, post-open context, and comparable markets — no probability forecasts

## 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 polymarket-intelligence-api-market-resolution-dossier-d3369aac
```

Example prompt: Can you pull the resolution-integrity dossier for Polymarket market 0x3a4c2b7d1e8f9a0b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5e6f7a8b — I want to see the UMA oracle exposure, any proposer and disputer records, and what comparable markets look like?

## When to prefer this

Use this endpoint when you need structured, on-chain-verified resolution integrity data for a specific Polymarket market — particularly proposer/disputer records from DisputePrice events, post-open context with a defined window, and comparable markets with named denominators. Prefer this over the free alternatives (dash.polym.uk/calibration.json, gamma-api.polymarket.com) when you need per-market proposer/disputer history, named comparables, or context appended after market open. Do not use this for price forecasting or probability estimates — it is strictly a factual dossier.

## Known failure modes

- 422 returned if conditionId is not in the currently covered market set — no charge applied
- Invalid conditionId format (not a 0x-prefixed 64-hex-char string) will fail schema validation
- Market may have partial coverage if some data dimensions are unavailable (coverage.level = 'partial')
- Payment failure or insufficient USDC balance prevents the paid call from completing
- conditionId outside the active observation window returns not-found response

## How this service works

Resolution-integrity dossier for one Polymarket market: UMA exposure, proposer and disputer records, post-open context, comparables. Never a forecast. BEFORE YOU PAY: free substitute https://dash.polym.uk/calibration.json and https://dash.polym.uk/uma-flip-rate.json and gamma-api.polymarket.com. THIS ADDS: Proposer/disputer records from DisputePrice on chain, denominator named; context appended AFTER the market opened, window stated; comparables. No probability: observations are not independent.

## Output

A JSON dossier containing: timestamp (asOf), the market question, coverage level (full or partial) with any missing fields noted, UMA oracle exposure details, rule integrity assessment, proposer and disputer on-chain records, comparable markets with base rates and story concentration, post-open price context with observation window, and a list of caveats. Returns 422 (unbilled) if the conditionId is outside the currently covered market window.
