Retrieve AWS secrets via a pay-per-call x402 endpoint on Base (USDC, $0.02/request).
What it does
This endpoint at lowpaymentfee.com exposes an AWS secret retrieval service behind the x402 payment protocol. Callers send a POST request to `/api/v1/integrations/aws/secret` with an `X-PAYMENT` header containing a valid x402 payment proof. The endpoint settles payments in USDC on the Base network using the "exact" scheme. The advertised maximum amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per request.
The provider's landing page lists a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, infrastructure utilities, and integrations — all priced uniformly at $0.02 per request. This specific endpoint falls under an integrations category and appears to proxy or retrieve secrets stored in AWS (likely AWS Secrets Manager). No OpenAPI schema, request body documentation, or response examples are published, so the exact input parameters and response shape are unknown.
Key operational details: no API keys are required (payment is the authentication), the provider claims no rate limits, and the x402 challenge specifies a 300-second timeout for payment settlement. The pay-to address is `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` and the USDC asset contract is `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base mainnet.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no published OpenAPI schema, no request/response documentation, and no examples. The exact purpose ('AWS secret') is only inferable from the URL path. The request and response shapes are entirely unknown, making this effectively a stub listing.
Warnings
- —No OpenAPI or request/response schema published — input parameters are unknown
- —No documentation beyond the URL path to explain what 'aws/secret' actually returns
- —Example request JSON is speculative based on the URL path; actual required fields are undocumented
- —Security implications: retrieving secrets via a third-party proxy raises trust concerns
