GET /api/v1/market-pulse

live

Use to find the day's biggest movers in one call. Returns the top 10 gainers and top 10 losers by percent move with price, the current US market session status (open, closed, pre, or post), and the latest market news headlines. No ticker needed. Built for agents scanning what is moving today. From x402stock, a pay-per-call market & economic data API. Pay per request in USDC via x402, no API key.

Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).

curl -si -X GET 'https://agents.x402stock.xyz/api/v1/market-pulse' -H 'accept: application/json'

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
