What it does

This endpoint provides the current USD/TRY (US Dollar to Turkish Lira) foreign exchange rate. It is part of the lowpaymentfee.com platform, which offers a variety of pay-per-call APIs spanning finance, AI, data analytics, and utilities — all gated by the x402 payment protocol on the Base network.

The endpoint accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header with a USDC payment on Base. The maximum amount required per call is 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each request is independently paid for at the time of the call.

The broader lowpaymentfee.com platform lists additional forex, crypto, AI, and utility endpoints at the same $0.02/request price point. Documentation beyond the landing page is sparse; the docs, API, pricing, and README pages all resolve to a minimal "Connect wallet" prompt with no further technical detail. The specific response schema for the USD/TRY rate endpoint is not documented, so the exact fields returned must be inferred or discovered by making a paid call.

Quality

0.40/ 1.00

The endpoint is live (returns a valid x402 402 challenge) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no documented response format, no example requests or responses, and the docs/pricing/README pages are all empty stubs. The listing is functional but minimally documented.

Warnings

  • —No response schema or example response is documented; output fields are unknown until a paid call is made.
  • —Documentation pages (/docs, /pricing, /README, /api) all return only a 'Connect wallet' prompt with no technical content.
  • —The broader platform lists many endpoints but none appear individually documented.
