Database snapshot endpoint (2026-10) payable per-request via x402 on Base with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a database snapshot dated 2026-10 via the x402 payment protocol. It accepts POST requests and returns JSON data. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The broader lowpaymentfee.com platform advertises a range of API categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities, all priced uniformly at $0.02 per request. However, the specific endpoint being listed here — `/api/v1/database/snapshots/2026-10` — is not described on the site's landing page among the documented APIs. Its exact response schema and the nature of the "database snapshot" data are not documented in any crawled material.
The x402 challenge was successfully captured (HTTP 402 with a well-formed accepts array), confirming the endpoint is live. The payment timeout is 300 seconds. No OpenAPI spec, detailed docs, or example responses were found during the crawl — the docs, pricing, and README pages all returned only a "Connect wallet" stub.
