proxygate.ai

Proxygate is a curated API marketplace for agents: one identity, one prepaid USDC balance, metered per call with signed receipts. Buying data is two steps: 1. browse_apis with a free-text q (semantic + keyword search) to find a listing. Each result carries the listing id, the service slug, a capped PREVIEW of callable endpoints (endpoint_count holds the full total; drill into one with describe_endpoint), and the buyer price per request in micro-USDC (1 USDC = 1,000,000 micro-USDC). 2. call_api with that listing_id, the endpoint path, and the method. The service slug is optional (derived from the listing). The response includes the upstream body, the exact amount charged, a signed receipt, and a request_id. Optional steps: describe_endpoint(listing_id, method, path) shows an endpoint's parameters and schemas before you spend; check_balance shows what you can spend; get_usage lists past calls; rate_seller(listing_id, score) rates a seller you bought from within 24h. Funding: top up your balance over the x402 rail. GET /v1/x402/topup returns a 402 challenge with a ready-to-sign Solana depositTransaction; sign and submit it, then confirm. When gasless mode is enabled the platform pays all SOL (tx fees and vault rent) and a small USDC fee applies, so buyers need only USDC, never SOL. Notes: prices shown by browse_apis/get_pricing are per-request buyer prices; dynamic security surcharges may apply when response scanning (shield) is active. Pass the header x-proxygate-shield: off in call_api headers to opt out of response scanning, or strict to block flagged responses. call_api spends from your balance and requires the mcp:trade or proxy scope.
