{"entry":{"slug":"exchangerebel-api","name":"ExchangeRebel","category":"api","summary":"Pay-per-call HTTP APIs for agents with free catalogue reads and route-level x402 pricing on Solana.","description":"Distinct HTTP API surface alongside the separately listed ExchangeRebel MCP server. On October 31, 2026, GET /openapi.json returned OpenAPI 3.0.3 with 345 documented paths, and the documented free GET /toll/packs/catalog returned a complete JSON catalogue with five packs. GET /api/listings also returned a five-entry public service directory. These are catalogue/configuration responses, not evidence of paid data delivery. Paid routes use x402 on Solana; accepted SOL or USDC and current price depend on the route/payment challenge. Inspect the specific operation and obtain explicit user consent before paying or taking consequential actions. No paid operation or payment was tested.
