Crypto token data for ANKR via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides token-level data for ANKR (Ankr Network) as part of a broader suite of finance, crypto, AI, and utility APIs. The specific resource `/api/v1/tokens/ANKR` is accessed via HTTP POST and gated by the x402 payment protocol, settling in USDC on the Base network at $0.02 per call (20,000 base units with 6 decimals). No API keys or rate limits are required — each request is individually paid for via the X-PAYMENT header.
The provider's landing page lists a wide catalog of endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all uniformly priced at $0.02 per request. However, documentation beyond the landing page is essentially empty (all sub-pages just show a "Connect wallet" prompt), so the exact response schema for this token endpoint is unknown. Based on the URL pattern and the site's Finance & Web3 category (which includes price feeds, exchange rates, token quotes, and gas estimates), this endpoint likely returns market or metadata information for the ANKR token.
The endpoint is live and responds with a valid x402 challenge (HTTP 402) confirming payment parameters. Settlement is to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base. The maximum timeout for payment is 300 seconds.
