Aave TVL data via x402 micropayment on Base — $0.02 per request, no API key needed.
What it does
This endpoint provides Aave DeFi Total Value Locked (TVL) data through the x402 payment protocol. It is hosted at lowpaymentfee.com, a platform offering various pay-per-call APIs across data analytics, AI/ML, finance/Web3, and infrastructure categories. All endpoints on the platform share a uniform pricing model of $0.02 per request, settled in USDC on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers include an X-PAYMENT header with a signed payment of up to 20,000 base units of USDC (i.e., $0.02, since USDC uses 6 decimals). There are no API keys, no rate limits, and no subscription commitments — access is instant once payment is attached to the request.
The platform advertises itself as a low-fee, permissionless API marketplace. Documentation and detailed response schemas are not publicly available beyond the landing page listing. The specific fields returned by the Aave TVL endpoint are not documented in the crawled material, so consumers should expect a JSON object with TVL-related metrics but should verify the exact schema by making a paid call.
