STORJ liquidity data via pay-per-call x402 on Base (USDC, $0.02/request)
What it does
This endpoint provides DeFi liquidity data for the STORJ token, accessible at https://lowpaymentfee.com/api/v1/defi/STORJ/liquidity. It is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities—all gated by the x402 payment protocol on the Base network using USDC.
The endpoint accepts POST requests and returns JSON. Payment is handled inline via the X-PAYMENT header using the x402 exact scheme. The advertised maximum cost is 20,000 base units of USDC (6 decimals), which equals $0.02 per request—consistent with the site's uniform $0.02 pricing across all listed endpoints. No API keys or rate limits are required; access is granted immediately upon valid payment.
Documentation beyond the landing page is extremely 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 request/response schema, and no example payloads available. The endpoint is confirmed live (returns a proper 402 challenge), but the exact request body format and response structure for STORJ liquidity data must be discovered by the caller.

Quality
The endpoint is confirmed live with a valid x402 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation, and no examples. The actual data returned is entirely unknown—only the token (STORJ) and category (DeFi liquidity) can be inferred from the URL path. This is effectively a stub listing.
Warnings
- —No API documentation available—/docs, /pricing, /api, and /README pages all show only a wallet-connect prompt
- —No request body schema or response schema provided; callers must discover the interface by experimentation
- —The endpoint description is generic ('Premium API Access') and does not describe the actual data returned
