How this service works
Micropay research APIs (x402 v2 + bazaar). Free catalog at /.well-known/x402.json. Primary v2 accepts: Base eip155:8453 only. Legacy X-PAYMENT-TX still supports bsc|base via acceptsV1. Headers: X-PAYMENT-TX, X-PAYMENT-NETWORK, PAYMENT-SIGNATURE. No financial advice.
Output
Returns a JSON object with an 'ok' status flag, a 'digest' object listing the aggregated sources (e.g. Polymarket, Kalshi), and a 'product' identifier ('pm_digest'). The digest provides a cross-platform summary of prediction market data pulled from multiple sources.

Technical details
Endpoint
GEThttps://desk-x402.desk-x402-gh.workers.dev/v1/pm-digestWhen to prefer
Choose this endpoint when you need a single aggregated digest of prediction market data spanning both Polymarket and Kalshi, and you are comfortable paying $1 USDC per call via the x402 micropayment protocol on the Base blockchain. It is ideal for research agents, trading bots, or analysts who want cross-platform prediction market coverage without querying each exchange separately.
Side effects
- Payment not included or invalid: 402 Payment Required — must include valid X-PAYMENT-TX header with 1 USDC on Base (eip155:8453)
- Unsupported network: payment on non-Base network rejected by v2 endpoint (BSC only supported via legacy acceptsV1 path)
- Invalid or missing PAYMENT-SIGNATURE header: authentication failure
- Upstream source unavailability: Polymarket or Kalshi data may be partially unavailable, resulting in incomplete digest
- Rate limiting or quota exceeded: repeated calls without valid fresh payment transactions rejected
