Pay-per-call HBAR token data via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides token data for HBAR (Hedera) through an x402-gated API. The specific endpoint `/api/v1/tokens/HBAR` sits within a broader suite of finance and crypto endpoints offered by the same provider. Payment is handled via the x402 protocol on the Base network using USDC, with each request costing $0.02 (20,000 base units of USDC with 6 decimals). No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider's landing page lists a wide catalog of endpoints spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all uniformly priced at $0.02 per request. However, documentation is extremely thin: the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns a proper 402 challenge on POST), but the actual response format and accepted input parameters for the HBAR token endpoint are unknown.
Because of the lack of documentation, callers should expect to experiment with POST request bodies to discover the expected input format. The x402 challenge confirms the endpoint accepts POST requests and returns application/json.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no documentation, no OpenAPI spec, no request/response examples, and the docs pages are empty. The actual functionality of the HBAR endpoint is entirely undocumented.
Warnings
