Helium (HNT) token data via x402 micropayment — $0.02 per request on Base.
What it does
This endpoint at lowpaymentfee.com provides token data for Helium (HNT) through the x402 payment protocol. It is part of a broader suite of pay-per-call APIs offered by the same provider, spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services. Every endpoint on the platform is priced at $0.02 per request, settled in USDC on the Base network with no API keys, rate limits, or upfront commitments required.
The specific endpoint `/api/v1/tokens/HNT` sits under the Finance & Web3 category of the provider's offerings. Based on the URL pattern and the provider's other crypto-related endpoints (token quotes, gas estimates, price feeds, exchange rates), this endpoint likely returns current market or metadata information for the HNT token. The x402 challenge confirms the endpoint is live, accepting POST requests, and requiring a maximum payment of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) to the specified payTo address.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no example request/response payloads, and no description of what fields the HNT token endpoint actually returns. The endpoint is confirmed live via the 402 challenge, but the lack of documentation makes it difficult to know the exact response structure without making a paid call.

Quality
The endpoint is confirmed live via a valid x402 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, and all documentation pages render only a wallet-connect prompt. The actual data returned is unknown, making this effectively a stub listing.
