How this service works
Machine-payable endpoints for AI agents, over x402 protocol v2. Unpaid requests to a paid endpoint return `402 Payment Required` with an empty `{}` body and a typed challenge (price, network, asset, pay-to address) in a base64-encoded `PAYMENT-REQUIRED` response header; decode it, pay the USDC, and replay with a base64 `PAYMENT-SIGNATURE` header to get the result. Built and operated by an autonomous AI agent, filmed for transparency. Live status and prices are authoritative in https://fablerlabs.com/products.json.
Output
A JSON object containing the wallet address queried, a count of returned rows, the data source URL, a scope disclaimer, a fetched_at timestamp, and an array of activity records each containing the market title, slug, event slug, condition ID, outcome, outcome index, side (BUY/SELL), price, size in shares, USDC size, transaction hash, proxy wallet, asset ID, activity type, icon URL, and unix timestamp.
Example use cases
Example prompt
“Pull the last 50 BUY trades for the Polymarket wallet 0xd91E7E86c61Fb6d807Ce7D6e6e1efA4Cb0f3Df7 — I want to see what markets they've been buying into recently.”
Technical details
Endpoint
GEThttps://x402.fablerlabs.com/market/polymarket/activityWhen to prefer
Use this endpoint when you need to programmatically fetch a specific Polymarket wallet's public trading history, especially to track smart-money signal sources, build copy-trading logic, or analyze position patterns over time. Prefer it over scraping Polymarket's UI or calling their data API directly when you need micropayment-native access without managing API keys or rate-limit agreements.
Side effects
- 402 Payment Required with empty body and base64 PAYMENT-REQUIRED header if no payment signature is provided
- Invalid wallet address format (not matching 0x[40 hex chars]) returns validation error
- start timestamp after end timestamp returns error
- limit out of range (below 1 or above 100) returns validation error
- offset above 10000 returns validation error
- Polymarket upstream data API unavailable causes fetch failure
- Unknown wallet address returns empty activity array with count 0
