BLK stock earnings data via x402 micropayment on Base network, $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides financial earnings data for the ticker symbol BLK (BlackRock, Inc.) through the x402 payment protocol. It is part of a broader suite of finance and Web3 APIs offered by the same provider, all priced at $0.02 per request and settled in USDC on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers include an X-PAYMENT header with a signed payment of up to 20,000 base units of USDC (i.e., $0.02, since USDC uses 6 decimals). No API keys or accounts are required — access is granted per-request upon valid payment. The provider advertises no rate limits and instant access.
The specific response schema for the /finance/BLK/earnings endpoint is not documented in the crawled material. Based on the URL path and the provider's "Finance & Web3" category (which includes price feeds, exchange rates, token quotes, and gas estimates), this endpoint likely returns structured earnings data for BLK. However, the exact fields, historical depth, and data source are not specified in any available documentation. The docs, pricing, and API pages behind the provider's site all require a wallet connection and yield no further detail.

Quality
