Transaction receipt endpoint on Base, paid per-call via x402 with USDC.
What it does
This endpoint at lowpaymentfee.com retrieves a transaction receipt for a given transaction ID (in this case, ID 10). It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities. All endpoints are gated via the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint probed (`/api/v1/transactions/10/receipt`) accepts POST requests and returns JSON. The x402 challenge indicates a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). The provider advertises a flat $0.02/request pricing across all endpoints, with no API keys, no rate limits, and no minimum commitments required.
Documentation is extremely sparse. The landing page lists available endpoints and pricing, but the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical content. There is no OpenAPI spec, no request/response schema documentation, and no usage examples. The exact data returned by this receipt endpoint is unknown beyond the stated mime type of application/json.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming pricing and payment details. However, documentation is essentially nonexistent—no OpenAPI spec, no request/response schemas, no examples. The purpose of this specific receipt endpoint is only inferable from its URL path. This is effectively a stub listing.
Warnings
- —No API documentation available; /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no content.
- —No OpenAPI or schema definition found for request or response payloads.
- —The exact data returned by this endpoint is unknown; 'Premium API Access' is a generic description.
- —The endpoint path includes a hardcoded transaction ID (10); it is unclear how to query arbitrary transaction IDs.
