How this service works
Polymarket resolution watch: markets ending within N days (default 7) with UMA resolution status (proposed/disputed), UMA bond and reward, hours to resolution, last price, 24h volume, liquidity and a uma_risk flag for contested or undecided resolutions. Lets prediction agents avoid or exploit resolution risk. No charge on service failure. Ed25519-signed. $0.10 USDC per call via x402 on Base. Free trial: 3 calls per wallet with header X-WALLET.
Output
Returns a JSON object with a count of matched markets and an array of market records, each containing the market slug, end date, question text, UMA bond and reward amounts, UMA statuses (e.g. 'proposed'), yes price, 24h USD volume, hours until resolution, and a boolean UMA risk flag. Also returns the total number of UMA-risky markets in the result set and the days-ahead window used.
Example use cases
Arbitrage alert on disputed resolutions
“Check Polymarket right now for any markets resolving in the next 2 days that have UMA proposals marked as disputed or proposed — I want to see all of them regardless of volume, up to 50 markets.”
High-volume resolution monitoring
“Scan the next 14 days of Polymarket resolutions and filter to only markets with over $20000 in 24h volume — give me up to 20 results so I can track the big ones approaching settlement.”
Weekly prediction market risk briefing
“Give me a weekly rundown of the top 25 Polymarket markets closing in the next 7 days that carry UMA risk, with minimum $1000 daily volume — I want to know which questions might get challenged before they resolve.”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/polymarket-resolution-watchWhen to prefer
Use this endpoint when you need real-time awareness of Polymarket markets approaching resolution that carry UMA oracle dispute risk. It is specifically suited for agents monitoring prediction market arbitrage opportunities, dispute tracking, or settlement risk analysis. Prefer this over generic Polymarket API calls when UMA bond/reward/status signals and hours-to-resolution are the key variables, and when you want a pre-filtered, risk-annotated view rather than raw market listings.
Side effects
- days parameter out of range (must be 0-60) — likely returns validation error
- limit out of range (must be 1-100) — likely returns validation error
- Polymarket API unavailable upstream — may return 502 or empty result set
- No markets found matching filters — returns count:0 with empty array
- Payment failure or insufficient USDC — x402 payment required error before processing
