SiteCheck
A pay-per-call API aggregation platform designed for AI Agents, offering 132 HTTP tool endpoints. It accepts USDC on-chain payments through the x402 protocol, allowing data query services to be invoked without registration or an API key.
Timeline (last 90 days)
SiteCheck offers 132 tools, all exposed through a single HTTP endpoint, priced between $0.001 and $0.01 per call, with payment in USDC via the x402 protocol, requiring no account, API key or subscription.
SiteCheck's tools cover areas including on-chain and crypto data, business and public data, web processing and reference information, and text AI capabilities, including EVM/Solana balances, SEC filings, weather alerts, OCR, and summarization.
SiteCheck offers both OpenAPI and a remote MCP server as access methods, and the MCP endpoint address is https://api.sitecheck-api.workers.dev/mcp.
SiteCheck's official statement says that this week every tool was run against inputs with known answers and compared with official sources for units, decimal places, dates and missing fields; problematic tools were fixed, and tools that could not reliably access upstream sources were removed.
For SiteCheck calls, if the upstream data source call fails, that call is not billed.
For scenarios requiring high-frequency, large-volume calls, SiteCheck's per-call cost of $0.001 to $0.01 needs to be factored into budget assessments.
