What it does

This endpoint provides financial earnings data for American Express (ticker: AXP) through the x402 payment protocol. It is hosted on lowpaymentfee.com, a platform offering a variety of pay-per-request APIs spanning finance, analytics, AI, and infrastructure — all settled on the Base L2 network using USDC.

The specific endpoint `/api/v1/finance/AXP/earnings` sits within the Finance & Web3 category of the platform. The x402 challenge confirms the endpoint is live, accepting POST requests, and charges a maximum of 20,000 base units of USDC (0x8335…on Base), which equals $0.02 per request (USDC uses 6 decimals). Payment is made via the x402 exact scheme to the specified payTo address, with a 300-second timeout window. No API keys or rate limits are advertised; access is instant once payment is included in the X-PAYMENT header.

Documentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the earnings data schema returned. The endpoint likely returns JSON (mimeType is application/json), but the exact fields, coverage period, and data source are unknown.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no example payloads. The actual data returned is entirely unknown, making this 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 output schema provided; the structure of the earnings response is unknown.
  • —Data source, update frequency, and coverage period for AXP earnings are unspecified.
  • —No example request or response payloads available anywhere in crawled material.
