What it does

This endpoint at lowpaymentfee.com provides financial earnings data for Mastercard (ticker: MA) through the x402 payment protocol. It is part of a broader suite of finance and web3 APIs offered by the same provider, all settling payments in USDC on the Base L2 network.

The endpoint accepts POST requests and returns JSON. Each call costs $0.02 in USDC (maxAmountRequired of 20,000 base units with 6 decimals). Payment is made via the x402 exact scheme — no API keys, subscriptions, or rate limits are required. The provider advertises instant access with no minimums or commitments.

Documentation is extremely sparse. The provider's landing page lists many API categories (data & analytics, AI/ML, finance & web3, infrastructure) but the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further detail. There is no OpenAPI spec, no request/response schema documentation, and no usage examples available. The specific fields returned by the /finance/MA/earnings endpoint (e.g., EPS, revenue, reporting dates) are unknown and must be discovered by calling the endpoint.

Quality

0.30/ 1.00

The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC per call on Base). However, there is no documentation, no OpenAPI spec, no request/response schema, and no examples. The specific data returned by the earnings endpoint is entirely unknown. This is effectively a stub listing.

  • —No request or response schema provided; output fields are unknown
  • —No OpenAPI or ai-plugin manifest found
  • —The endpoint path suggests Mastercard (MA) earnings but this is inferred from the URL only
  • —Provider lists many endpoints but none have documented schemas
