Pay-per-call TRX 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 TRX (TRON) as part of a broader suite of finance and crypto APIs. It is accessed via the x402 payment protocol: each POST request requires an X-PAYMENT header containing a USDC payment on the Base network. The price per call is $0.02 (20,000 base units of USDC with 6 decimals). No API keys or accounts are required — payment is the authentication.
The provider offers a wide catalog of endpoints spanning data analytics, AI/ML inference (sentiment, summarization, classification, embeddings), finance (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation), all at the same $0.02/request price point. The specific endpoint `/api/v1/tokens/TRX` falls under the Finance & Web3 category and likely returns token-level data for the TRX cryptocurrency.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the TRX token endpoint actually returns. The endpoint is confirmed live (returns a valid x402 402 challenge), but the lack of documentation makes it difficult to know the exact request format or response structure without making a paid call.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages render only a wallet-connect prompt. The actual data returned by the TRX endpoint is unknown.
