Pay-per-call token data API for APT via x402 on Base network, $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides token data for APT (Aptos) via a simple POST request, settled per-call using the x402 protocol on the Base network. Payment is made in USDC at $0.02 per request with no API keys, no rate limits, and no subscriptions required.
The provider operates a broader platform offering multiple API categories including data & analytics, AI & machine learning (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints share the same $0.02/request pricing model.
The specific endpoint `/api/v1/tokens/APT` appears to be a token information or quote endpoint for the APT token. The x402 challenge confirms the endpoint is live, accepts USDC on Base (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913), and requires a maximum payment of 20000 base units (i.e., $0.02 given USDC's 6 decimals). No OpenAPI schema or detailed documentation was found beyond the landing page listing.
