It accepts a market ID and question, then returns AI-generated context (breaking news, sentiment, source citations) alongside smart money signals (suspicious wallets, insider confidence, holder positions, trade recommendations). Priced at $0.09 USDC per call on Base, it is 10% cheaper than calling `/market-context` ($0.05) and `/smart-money` ($0.05) individually.\n\nThe endpoint is part of a broader PolyNews API suite that covers Polymarket and Kalshi prediction markets. The API uses the x402 micropayment protocol — no API keys or subscriptions required. Agents pay per call in USDC on Base via the x402 facilitator. Free endpoints are available for market discovery (`/markets`, `/live-prices`), while paid tiers range from $0.001 for trade feeds up to $0.10 for deep combo analyses. The full OpenAPI 3.1 spec and JSON docs are published at the provider's site.\n\nThe `market-deep` endpoint requires a POST with `marketId` and `marketQuestion` as required fields, plus optional `marketOdds`, `conditionId`, and `outcomeName` for multi-outcome markets. The response contains a `context` object (equivalent to `/market-context` output) and a `smartMoney` object (equivalent to `/smart-money` output), along with a `partialFailure` boolean indicating if one sub-call failed while the other succeeded.","tags":[],"capabilities":["grok-ai-analysis","smart-money-detection","prediction-market-intelligence","polymarket-data","news-sentiment-analysis","x-twitter-analysis","insider-signal-detection","wallet-analysis","x402-micropayment","combo-endpoint"],"categories":["llm","search","finance"],"synonyms":["prediction market analysis","polymarket AI","smart money tracker","market intelligence API","Grok market context","prediction market smart money","polymarket news analysis","x402 prediction market","market deep analysis"],"warnings":["Response sub-objects (context, smartMoney) are described as generic 'object' types in the OpenAPI spec without fully expanded property definitions","Example response is inferred from combining /market-context and /smart-money schemas; no actual 200 response was captured"],"endpointUrl":"https://polynews.news/api/v1/market-deep","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x6ee49a7872844397Fb52870Cc07b308fFADC9427","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://polynews.news/api/v1/market-deep","description":"Grok-powered news/X analysis + smart money detection in one parallel call. 10% cheaper than calling market-context + smart-money individually.","outputSchema":{"input":{"type":"http","method":"POST","bodyType":"json","bodyFields":{"marketId":"69317","marketOdds":"Yes: 72%","marketQuestion":"Democratic Presidential Nominee 2028"},"discoverable":true},"output":{"type":"object","properties":{"data":{"type":"object","properties":{"smartMoney":{"type":"object","description":"Smart money detection results"},"marketContext":{"type":"object","description":"Grok-powered news and X analysis"},"partialFailure":{"type":"boolean"}}}}}},"maxAmountRequired":"90000","maxTimeoutSeconds":300}]},"qualityScore":"0.900","qualityRationale":"Full OpenAPI 3.1 schema with detailed request/response definitions, live 402 challenge captured confirming the endpoint is operational, comprehensive docs page with pricing tiers and quick-start code, and clear x402 payment parameters.
