What it does

This x402-enabled endpoint at `/api/v1/forex/CADJPY` provides CAD/JPY foreign exchange rate data. It is part of a broader suite of APIs offered by lowpaymentfee.com spanning finance, analytics, AI/ML, crypto, and utility services. All endpoints on the platform use the x402 payment protocol, accepting USDC on the Base network with no API keys, no rate limits, and no commitments required.

The endpoint accepts POST requests and returns JSON. Each call costs $0.02 in USDC (20,000 base units of USDC with 6 decimals = $0.02), settled on-chain to the provider's wallet on Base. The x402 challenge was confirmed live, returning a standard 402 Payment Required response with version 1 of the x402 protocol and a 300-second payment timeout.

Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the forex endpoint returns. The endpoint is clearly live and priced, but the lack of documentation means callers must discover the response format experimentally.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02/call in USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages return only a wallet-connect prompt. The actual response format for the forex endpoint is unknown, making this effectively a stub listing.

Warnings

  • —No API documentation available — docs, pricing, and README pages all render only 'Connect wallet'
  • —No OpenAPI or JSON schema describing request parameters or response fields
  • —The /api/v1/forex/CADJPY path is not listed on the provider's homepage; it may be an unlisted or experimental endpoint
  • —Response format must be discovered experimentally; no examples exist in crawled material
