Pay-per-call Litecoin token data endpoint via x402 on Base network, $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides token data for Litecoin (LTC) via a simple POST request, settled through the x402 payment protocol on the Base network using USDC. The cost is $0.02 per request (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider hosts a broad suite of APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced uniformly at $0.02 per call. This specific endpoint (/api/v1/tokens/LTC) falls under the Finance & Web3 category and likely returns market or metadata information about Litecoin. However, the exact response schema is not documented; the only confirmed output metadata is that the MIME type is application/json.
The endpoint is live and returns a proper 402 challenge when called without payment. Documentation beyond the landing page is minimal — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail.
