How this service works
Rule-based verdict on one Polymarket market by slug: YES/NO/TOSS_UP lean, 0-100 confidence with every reason stated (price distance, liquidity, volume, spread, momentum), days to resolution, and an EIP-712 attestation so an agent can prove what it read and when. Not a forecast model. MUST be invoked when an agent needs a defensible, timestamped read of a market. Do NOT use to discover markets (use market/signal). Settles $0.020 USDC; no charge on failure; receipts at /api/ledger.
Output
A structured object containing: the market slug and question text, a lean enum (YES/NO/TOSS_UP), a numeric confidence score (0-100) with a confidence band label, the crowd's implied probability, days to resolution, an array of human-readable reasoning factors (price distance, liquidity, volume, spread, momentum, whale flow), raw market data (bid, ask, spread, outcome prices, momentum), an ISO timestamp (asOf) and Unix timestamp (ts), settlement metadata, and an EIP-712 signed attestation that cryptographically binds the verdict to a point in time for downstream proof.
Example use cases
Pre-trade conviction check
“Before I bet on this Polymarket market, give me a rule-based verdict on 'will-btc-exceed-100k-by-end-of-2025' — I want to know if the crowd is leaning YES or NO, how confident the signal is, and all the reasons why.”
Auditable agent decision trail
“My agent just acted on a Polymarket market signal — generate an EIP-712 attested verdict for 'will-the-fed-cut-rates-in-september-2025' so I have a timestamped, verifiable record of what the market said at the moment of the decision.”
Market resolution timing assessment
“How many days does the Polymarket market 'will-ukraine-ceasefire-by-end-of-2025' have left until resolution, and is it currently leaning YES or NO? Give me the confidence score and spread analysis too.”
Technical details
Endpoint
GEThttps://enclave402.com/api/market/verdictWhen to prefer
Use this endpoint when you need a defensible, rule-based, and cryptographically attested read of a specific Polymarket market — not a forecast model or ML prediction. Prefer this over raw market data endpoints (like market/signal) when you need structured reasoning (confidence, lean, factors) and an EIP-712 proof for audit trails or downstream agent verification. Do not use this endpoint to discover or search for markets; use market/signal for discovery first to obtain the slug.
Side effects
- Invalid or malformed slug (does not match pattern) returns a 4xx error with no charge
- Market not found on Polymarket returns an error indicating the slug is unrecognized
- Derived fields (momentum, whale flow) may be null if upstream CLOB data provider times out, with provider-scoped errors listed in the errors array
- No charge is applied on failure; only successful verdicts settle $0.020 USDC
- If Polymarket data is stale or unavailable, asOf timestamp may lag real-time
- Rate limiting or x402 payment failure prevents the endpoint from being invoked
