Pay-per-call stock market quote for VZ (Verizon) via x402 on Base, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides a market quote for the ticker symbol VZ (Verizon Communications) through the x402 payment protocol. It is one of many endpoints offered by the lowpaymentfee.com platform, which hosts a variety of data, analytics, AI, finance, and utility APIs — all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/market/quote/VZ` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment of up to $0.02 (20,000 base units of USDC with 6 decimals) to the payee address on Base. No API keys, accounts, or rate limits are required — access is purely pay-per-call.
The broader lowpaymentfee.com platform advertises additional categories of endpoints including sentiment analysis, text summarization, embeddings, price feeds, exchange rates, crypto gas estimates, geocoding, and more, all at the same $0.02 price point. Documentation pages exist but appear to require a wallet connection and contain no additional detail at crawl time, so the exact request/response schema for this market quote endpoint is not documented.

Quality
The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request body or response format, and the docs/pricing/README pages all render only a wallet-connect prompt with no useful content. The exact data returned by the market quote endpoint must be inferred from the URL path alone.
Warnings
- —No request or response schema is documented; the exact fields returned by the market quote endpoint are unknown.
- —Documentation, pricing, and README pages all render only a 'Connect wallet' prompt with no substantive content.
- —It is unclear whether the quote is real-time, delayed, or sourced from a specific data provider.
- —The endpoint path suggests a single-ticker quote; batch queries are not evidenced.
