Stock market quote for MDLZ (Mondelez) via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides a stock market quote for the ticker symbol MDLZ (Mondelez International) through the x402 payment protocol. It is part of a broader suite of APIs offered by lowpaymentfee.com, which spans data analytics, AI/ML inference, finance, crypto, and utility services — all gated behind x402 micropayments on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on Base (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are advertised; access is granted per-call via the x402 payment header. The x402 challenge was successfully captured, confirming the endpoint is live.
Documentation beyond the landing page is extremely thin — 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 response schema. The specific data source for the MDLZ quote (real-time vs. delayed, which exchange) is not documented. Prospective users should be aware that the actual response format and data freshness are unknown.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base per call), but there is no OpenAPI spec, no example request/response, no documentation of the response schema, and no information about data source or freshness. The docs pages are empty beyond a wallet-connect prompt. This is effectively a stub listing.
