Pay-per-call employee data API on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee data records via the x402 payment protocol. The specific resource `/api/v1/employees/1` returns JSON employee data for employee ID 1 when called with a valid x402 payment header. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals).
The provider lowpaymentfee.com hosts a broader suite of pay-per-call APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are advertised at the same $0.02/request price point with no API keys, no rate limits, and no minimum commitments.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed field documentation available from the crawl. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual response schema and accepted request body format are unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge, but documentation is effectively nonexistent — all doc pages show only 'Connect wallet'. No OpenAPI spec, no request/response schema, no examples. The actual data returned is unknown, making this essentially a stub listing.
Warnings
- —No documentation available — all doc/pricing/README pages render only 'Connect wallet'
- —No OpenAPI or response schema provided; actual response format is unknown
- —The endpoint path suggests a single hardcoded employee record (ID 1); unclear if parameterized access to other IDs is supported
- —Provider hosts many advertised endpoints but none have documented schemas
