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. 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
Returns a quote object with: expected number of shares received, average fill price per share, total fee charged, and price impact as a percentage deviation from the current spot price — all computed off-chain with no transaction submitted.
Example use cases
Pre-trade slippage check
“Before I commit, can you simulate buying YES on Panta market 9xW...k3q with my wallet 4rT...pLm for 100 USDC — I want to see the expected shares, fill price, fee, and how much my buy would move the price?”
Comparing YES vs NO buy cost
“Get me quotes for both a YES and a NO buy on Panta market BqR...7zJ using wallet 2mF...vNs and 20 USDC each — I want to compare the average fill prices and fees side by side.”
Small-stake prediction market entry
“I'm thinking of putting 5 USDC into a NO position on Panta market Ht4...8wY with wallet 6kP...rQc — can you preview how many shares I'd get and what the price impact would be before I decide?”
Technical details
Endpoint
POSThttps://api.sitecheck-api.workers.dev/api/markets/quote?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent or user wants to preview the economics of a Panta prediction market trade — expected shares, fill price, fee, and slippage — without executing or signing anything. Prefer this over live execution endpoints when validating trade parameters, comparing buy sides, or building pre-trade confirmation UX. It is read-only and safe to call repeatedly.
Side effects
- Invalid or unknown market ID returns an error (market not found)
- Invalid base58 wallet address causes a validation error
- amountUsdc of zero or negative value rejected
- side value other than 'yes' or 'no' rejected
- Insufficient liquidity in the market may result in an error or extreme price impact warning
- Network or worker timeout for slow market data fetches
