Pay-per-call stock/market quote for CRM (Salesforce) via x402 on Base, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides a market quote for the ticker symbol CRM (Salesforce) through a simple POST request. It is part of a broader suite of finance, analytics, AI, and utility APIs offered by the same provider, all priced at $0.02 per request and payable via the x402 protocol using USDC on the Base network. No API keys or accounts are required — payment is handled inline via the X-PAYMENT header.
The x402 challenge confirms the endpoint is live and accepts an exact payment scheme with a maximum amount of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals). The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base mainnet, with a timeout of 300 seconds. The response MIME type is application/json.
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 response schema for the quote endpoint. The endpoint likely returns standard market-quote fields (price, volume, change, etc.) for CRM, but this is inferred from the URL pattern and cannot be confirmed from available material.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no documented request/response schema, no example payloads, and all documentation pages return only a wallet-connect prompt. The actual data returned by the endpoint is entirely unknown.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All doc/pricing/README pages render only 'Connect wallet' with no technical content
- —No example responses or field definitions for the market quote endpoint
- —Provider offers a very broad set of endpoints (AI, analytics, finance, utils) all at $0.02 — unclear whether all are fully implemented
