What it does

This endpoint provides EUR/CHF foreign exchange rate data, accessible through the x402 payment protocol on the Base network. Each request costs $0.02 (20,000 base units of USDC with 6 decimals) and requires no API keys, accounts, or rate limits — payment is handled per-call via an X-PAYMENT header settled in USDC on Base.

The endpoint is part of a broader suite of APIs offered at lowpaymentfee.com spanning finance, analytics, AI/ML, crypto, and utility categories, all priced uniformly at $0.02 per request. The forex endpoint specifically serves the EUR/CHF currency pair. The response MIME type is application/json, and the endpoint accepts POST requests.

Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint is confirmed live (returns a valid x402 402 challenge), but the lack of documentation means the exact response format must be discovered by making a paid request.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid x402 402 challenge and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and all documentation pages beyond the landing page are empty. This is effectively a stub listing with verified liveness but minimal usable documentation.

Warnings

  • —No OpenAPI or schema documentation available — response format is unknown
  • —All doc/pricing/README pages render only 'Connect wallet' with no content
  • —No example request or response payloads available; exact data fields must be discovered empirically
  • —Provider offers many endpoints across diverse categories (AI, analytics, finance, utils) all at the same price — quality/depth of each is unverified
