Pay-per-call stock quote API for CRM (Salesforce) via x402 on Base, $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides stock data for the ticker CRM (Salesforce) through an x402-gated API. Each request costs $0.02 in USDC on the Base network, with no API keys, rate limits, or subscriptions required — callers simply attach an x402 payment header to a POST request and receive a JSON response.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per request. The x402 challenge confirms the endpoint is live, accepting USDC (contract 0x8335…2913) on Base with a max amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). Timeout is 300 seconds.
Documentation on the site is extremely thin — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of what fields the stock data response contains. The endpoint path suggests it returns data for the CRM ticker, but the exact schema is unknown.

Quality
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 documented request/response schema, no example payloads, and the docs pages are empty stubs. The actual data returned is entirely unknown, making this effectively a stub listing.
Warnings

- —The specific stock data fields (real-time vs delayed, OHLCV, etc.) are not documented anywhere
- —The /api/v1/stocks/CRM path is not listed on the homepage's API catalog, raising questions about whether it is a fully supported endpoint
