Historical stock price data for PNC via x402 micropayment on Base network.
What it does
This endpoint provides historical stock price data for PNC Financial Services Group (ticker: PNC) through the x402 payment protocol. It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance, crypto, and utility endpoints, all gated behind per-request x402 micropayments settled in USDC on the Base network.
The endpoint accepts POST requests and returns JSON. Each call costs a maximum of $0.02 (20,000 base units of USDC with 6 decimals) paid via the x402 X-PAYMENT header. The platform advertises no API keys, no rate limits, and instant access — you pay per request with no subscription or commitment.
Documentation beyond the landing page is extremely sparse; the /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The specific fields returned by the /stocks/PNC/history endpoint (e.g., date range parameters, OHLCV columns, pagination) are unknown and must be discovered empirically.

Quality
The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documented parameters, and no example payloads. Documentation pages are empty beyond a wallet-connect prompt, making this effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — request parameters and response format are unknown.
- —All documentation pages (/docs, /api, /pricing, /README) returned only 'Connect wallet' with no content.
- —The specific data returned by the stocks history endpoint (fields, date ranges, granularity) is undocumented and must be discovered by trial.
- —The platform lists many diverse endpoints (AI, finance, utilities) all at $0.02 — actual data quality and sources are unverified.
