How this service works
Pay-per-call tools for AI agents: image generation, speech-to-text, text-to-speech, embeddings, LLM chat, website audits and contact enrichment, web page to Markdown reader, PDF to text, sitemap URLs, tech stack detection, translation, exchange rates, e-mail pre-check, domain RDAP/DNS lookup, Solana token checks, trending tokens and wallet holdings, plus business and compliance data (EU VAT/VIES, IBAN, LEI/GLEIF, US recalls, OSHA/EPA violations, UK insolvency notices). Plus prediction-market search, briefs, quotes and unsigned buy transactions, powered by Panta. Payment: x402, USDC on Base, Solana or Arc. No signup, no API key.
Output
A JSON object containing a total count and a list of matching markets, each with a unique market ID, phase (primary/secondary/resolved/cancelled), buyable flag, closing timestamp, the market question, yes/no prices in USDC, total volume in USDC, a resolution source URL, and implied probabilities for yes and no outcomes. Also includes a Panta branding attribution and a financial disclaimer.
Example use cases
Crypto market odds research
“Find open prediction markets about BTC or Ethereum prices — I want to see the current yes/no odds and how much volume they have, up to 10 results.”
Politics prediction market discovery
“Search for open prediction markets in the politics category, limit to 5 results, so I can see what elections or political outcomes people are betting on.”
Resolved market outcome lookup
“Find resolved prediction markets about crypto that have already settled — show me up to 10 so I can see how past market predictions turned out.”
Technical details
Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/markets?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover or browse prediction markets by topic, category, or status without requiring authentication or an API key. Prefer this over direct Panta.market access when you want pay-per-call pricing with no signup overhead, or when integrating prediction market data into an agent workflow that already uses x402 micropayments on Base, Solana, or Arc.
Side effects
- No markets match the query keywords — returns empty results array with total 0
- Invalid status value returns an error or empty set
- Limit out of range (less than 1 or greater than 20) may be clamped or return an error
- Payment not accepted (insufficient USDC balance or unsupported chain) results in 402 response
- Network timeout on the workers.dev edge function
