OpenAPI Specification

info:
title: Datakoot x402 data Koot API
version: 2.8.0
x-guidance: 'Call POST /api/<tool> with a JSON body of the tool''s arguments (GET with a query string also works). Without payment you get HTTP 402 with an x402 v2 challenge (PAYMENT-REQUIRED header and JSON body): pay $0.01 USDC on Base (eip155:8453) to the listed payTo using the exact scheme, then retry with the PAYMENT-SIGNATURE header. Datakoot verifies the payment, runs the tool, and settles only if the tool succeeds; a tool error returns 422 with charged:false. Successful responses are plain JSON matching each operation''s 200 schema, with the on-chain receipt in PAYMENT-RESPONSE. Start with cve_lookup, package_health, financials, country_profile or domain_report. MCP clients can use /mcp; every tool is also free for 100 calls/day at <server>.datakoot.com/mcp.'
description: 48 live public-data tools (security, packages, SEC filings, economy, FX, weather, domains, Federal Register, Base) plus 4 Koot briefing tools that combine many lookups into one answer, for AI agents. $0.01 USDC per call (every tool and every Koot brief) on Base via x402, charged only on success. The same tools are free for 100 calls/day via MCP at .datakoot.com/mcp.
