Get the current price of the ARB token via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current price of the Arbitrum (ARB) token. It is part of a broader suite of APIs offered by lowpaymentfee.com, which covers data analytics, AI/ML inference, finance/Web3 data, and utility services — all payable per request via the x402 protocol on the Base network using USDC.
The specific endpoint at `/api/v1/tokens/ARB/price` accepts POST requests and returns JSON. Payment is settled on-chain on Base using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`). The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals). No API keys or rate limits are advertised; access is gated solely by the x402 payment header.
Documentation beyond the landing page is sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint is confirmed live (returns a proper 402 challenge), but the exact shape of the price data returned after payment is unknown.

Quality
The endpoint is confirmed live with a valid x402 402 challenge and clear pricing ($0.02/request in USDC on Base). However, there is no OpenAPI spec, no example request/response, and all documentation pages beyond the landing page are empty ('Connect wallet' only). The response schema is entirely unknown, making this effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All doc/pricing/README pages return only a 'Connect wallet' prompt with no content
- —The endpoint path suggests token-specific pricing but no details on supported tokens or response fields are documented
- —No SLA, rate-limit, or uptime guarantees are published
