Filecoin (FIL) token data via pay-per-call x402 endpoint on Base, $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides token data for Filecoin (FIL) as part of a broader suite of finance and crypto APIs. It uses the x402 payment protocol, accepting per-request payments of $0.02 in USDC on the Base network. No API keys, accounts, or rate limits are required — each call is individually settled on-chain.
The provider's site lists a wide catalog of endpoints spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities, all priced uniformly at $0.02 per request. This specific endpoint (`/api/v1/tokens/FIL`) falls under the crypto/finance category and likely returns price or market data for the FIL token, though the exact response schema is not documented. The x402 challenge confirms the endpoint is live, accepting POST requests, and settling via USDC (contract 0x8335…) on Base.
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 spec, no example request/response, and no description of what fields the FIL token endpoint returns. Users should expect to experiment with the endpoint to discover its output format.

Quality
The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no examples, and the docs pages are empty. The actual data returned is unknown, making this effectively a stub listing.
Warnings
