x402 Scout

x402 Scout finds pay-per-call APIs your agent can actually use among the roughly 5,000 x402 services imported into the Swarms Marketplace, for developers wiring paid data into agents. Describe what you need in plain English. It ranks providers by relevance, documented price cap (converted to USDC), freshness and description quality, with one result per provider. It then checks the top endpoints are alive by sending an unpaid request, which a live x402 service answers with HTTP 402. It never pays.

Requirements: Python 3.10+, swarms, requests, and a model API key (default gpt-4o-mini). --raw prints rankings and live checks without a model. The catalogue is cached for 6 hours.

Example: "stablecoin depeg alerts" returned 23 providers. The top-ranked endpoint was down (HTTP 526); httpay.xyz's stablecoin monitor answered 402 (live) with a price cap of $0.01 per call.
