x402-gated token data endpoint for LRC (Loopring) on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides token data for LRC (Loopring) via the x402 payment protocol. It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services — all gated behind x402 challenges on the Base network.
The specific endpoint `/api/v1/tokens/LRC` returns JSON data related to the LRC token. Based on the site's other finance and crypto endpoints (price feeds, token quotes, exchange rates, gas estimates), this likely returns pricing or market data for Loopring's LRC token, though the exact response schema is not documented. Payment is settled in USDC on Base at $0.02 per request (maxAmountRequired of 20,000 base units with 6 decimals = $0.02). No API keys or rate limits are advertised; access is granted purely through the x402 payment header.
The platform's documentation pages are essentially empty (showing only a "Connect wallet" prompt), so there is no detailed schema, example request/response, or parameter documentation available. The endpoint is confirmed live — it returns a well-formed 402 challenge with x402 Version 1. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using the USDC contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base.

Quality
The endpoint is confirmed live with a valid x402 challenge and clear pricing ($0.02 USDC on Base). However, documentation is essentially nonexistent — no response schema, no request parameters, no examples. The exact data returned is inferred from the URL pattern and sibling endpoints, not documented.
