Real-time stock price data for TMO (Thermo Fisher Scientific) via x402 micropayment on Base.
What it does
This x402 endpoint returns the current stock price for Thermo Fisher Scientific (ticker: TMO) as JSON. It is part of a broader suite of pay-per-request APIs hosted at lowpaymentfee.com, covering data analytics, AI/ML inference, finance, crypto, and utility services. The endpoint accepts POST requests and settles payments in USDC on the Base network using the x402 protocol.
Pricing is $0.02 per request (20,000 base units of USDC with 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each call is paid individually via the X-PAYMENT header. The x402 challenge was confirmed live, returning a 402 with a well-formed payment challenge specifying the USDC asset contract on Base (0x8335…2913) and a payTo address.
The provider's landing page lists many other endpoints across categories like sentiment analysis, text summarization, exchange rates, and geocoding, all at the same $0.02/request price point. Documentation pages beyond the landing page returned only a "Connect wallet" stub, so detailed request/response schemas for this specific stock price endpoint are not available from the crawl.

Quality
The endpoint is confirmed live via a well-formed 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format for this specific stock endpoint, and all docs pages returned only a wallet-connect stub. The listing is largely inferred from the URL path and landing page context.
Warnings
- —No request or response schema available — the exact JSON shape returned is unknown.
- —Documentation pages (/docs, /api, /pricing, /README) all returned only 'Connect wallet' with no usable content.
- —The specific stock price endpoint (/api/v1/stocks/TMO/price) is not listed on the provider's landing page; only generic finance endpoints are shown. It may be undocumented or experimental.
