TaskHawk Systems
TaskHawk Systems, LLC (Charlottesville, Virginia) builds operational verification infrastructure for autonomous AI and software systems. Its commercial product, Kevros, is a verified release and evidence gateway: before an agent spends, deploys, sends or actuates, it POSTs the proposed action to the Kevros Governance API and receives a signed ALLOW, CONSTRAIN or DENY decision with a release token, recorded in a hash-chained, post-quantum-signed provenance ledger. The gateway at governance.taskhawktech.com publishes an OpenAPI 3.1 contract (23 operations: verify, attest, bind, verify-outcome, bundle, prompt-injection shield scan, media hash attestation, MPP payment sessions), a hosted Streamable HTTP MCP server with 9 tools, an A2A agent card, RFC 8414 authorization-server metadata, and per-call machine payment discovery over x402 (USDC on Base), L402 (Lightning) and MPP (Stripe) rails with a 1,000-call trial allowance via POST /signup.
TaskHawk Systems publishes 6 API contracts indexed on the APIs.io network, including Billing API, Governance API, Media API, and 3 more. Tagged areas include AI Governance, Agent Security, Runtime Enforcement, Policy Enforcement, and Provenance.
TaskHawk Systems’ developer surface includes authentication, documentation, API reference, getting-started guide, support, pricing, signup flow, and 34 more developer resources.
