x402-payable token data endpoint returning ARB token information for $0.02 per request on Base.
What it does
This endpoint at lowpaymentfee.com provides token data for ARB (Arbitrum) via an x402 payment-gated API. It is part of a broader platform offering dozens of endpoints across data/analytics, AI/ML, finance/Web3, and infrastructure categories, all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/tokens/ARB` sits under the Finance & Web3 category and likely returns token-level information such as price quotes or metadata for the ARB token. The x402 challenge confirms the endpoint is live, accepting POST requests, and requires an exact payment of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.
The platform advertises no API keys, no rate limits, and instant access. Documentation pages (/docs, /pricing, /README) returned only a "Connect wallet" prompt with no substantive content, so the exact response schema and request parameters for this endpoint are unknown. Without documentation or example responses, the precise fields returned remain unclear.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no documentation, no OpenAPI schema, no example request/response, and the docs/pricing/README pages are all empty stubs. The exact data returned is unknown.
Warnings
- —No API documentation available — /docs, /pricing, and /README pages all return only a wallet-connect prompt with no content.
- —Response schema is completely unknown; no example responses or field descriptions exist.
- —The specific endpoint /api/v1/tokens/ARB is not listed on the homepage (only /api/v1/crypto/quotes and similar are shown), so its exact purpose is inferred.
