What it does

This endpoint at lowpaymentfee.com provides token data for VET (VeChain) through an x402-gated API. The endpoint is live and returns a 402 challenge requiring payment of up to 20,000 base units of USDC on the Base network, which translates to $0.02 per request (USDC uses 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to access the resource.

The provider operates a broader platform offering dozens of pay-per-call endpoints across categories including data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request. This specific endpoint (/api/v1/tokens/VET) falls under the Finance & Web3 category and likely returns token-level data such as price, market cap, or related metadata for VET, though the exact response schema is not documented.

Payment is settled on the Base L2 network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with the "exact" payment scheme. The x402 challenge specifies a maximum timeout of 300 seconds and targets payTo address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3. The endpoint accepts POST requests and returns application/json. Documentation beyond the landing page is essentially empty (all doc pages just show "Connect wallet"), so the exact request body format and response structure remain unknown.

Warnings

  • The specific data fields returned for VET tokens are unknown and must be discovered empirically
  • Provider appears to be a generic multi-endpoint platform; quality and reliability of underlying data sources is unverified
