Traffic Parrot simulates APIs and messaging. Request or withdraw a trial, read docs, send feedback.
Deterministic preflight for FactoryTalk View tag and alarm CSV imports before re-import.
Deterministic release-compatibility preflight for OPC UA NodeSet2 XML.
Signed declarations of HTTP API exchanges for agent handoffs. Free preparation and verification; receipt issuance costs 0.002 USDC via x402 on Base. Start and connect: https://datoka.dev/api. Signatures attest declared data, not independent truth.
Developer checks and Agent Observatory: A2A, MCP and OpenAPI checks with a dated change log.

API documentation drifts away from the running service, so consumers integrate against a contract nobody keeps.

Agents can design endpoints, write and run test suites, manage mock servers and publish documentation, always under the permissions of the connected Routebase account.
Independent health, price and history for x402/MPP endpoints. Metered over x402; free grade on web.
AI-callable tools for API mocking, testing, monitoring, security, and automation.
Discovery registry for AI agents: 660+ APIs, MCP servers and CLIs, each health-checked every 6 hours with real requests — full initialize + tools/list handshakes for MCP, real calls for APIs — plus response-schema validation that catches responses which parse fine but are missing a required field.
Free MCP, API auth, webhook and schema diagnostics with bounded checks and safe quote routing.
