**APIs profiled:** 2

Checkpoint402 sells checked data for AI agents on a pay-per-call basis: transaction explanations for Base and Ethereum, DeFi yield discovery (DefiLlama), new-token and token safety checks (GoPlus, GeckoTerminal, DexScreener), SEC 8-K company events (SEC EDGAR) and US Treasury OFAC sanctions screening. Every service is a plain HTTPS GET on api.checkpoint402.com returning JSON, with no account or API key: each request is paid individually (from $0.02) in USDC on Base via the x402 HTTP payment standard, and failed requests are never charged. The same services are offered as a remote MCP server at https://api.checkpoint402.com/mcp.
