Contact: operations@blackknightstech.com. ## Products - [A.C.E.](https://blackknightstech.com/software/ace): Decision-support APIs that tell an automated system whether its evidence, data sources and releases are traceable enough to proceed, with every gap stated explicitly. - [TaskForge](https://blackknightstech.com/software/taskforge): Pay-per-call audit APIs that check agent permissions, MCP servers, CI/CD pipelines and API endpoints before you trust or ship them. Live on x402 agent marketplaces. - [ProofForge](https://blackknightstech.com/software/proofforge): Pay-per-call APIs that measure whether evidence supports a claim: support, contradiction, corroboration, freshness, provenance and completeness, returned as machine-readable results with methods and limits. Live on x402 agent marketplaces. - [ZEI](https://blackknightstech.com/software/zei): Scans checkout, sign-up and cancellation pages for hidden renewal terms, pre-ticked paid extras, missing prices, guilt-trip decline buttons and cancel-harder-than-sign-up flows, then returns a Ready, Conditional or Blocked decision with the evidence and the fix for each finding. ## Pay-per-call APIs Send a POST request; the endpoint returns HTTP 402 with the price; pay with an x402 client and the result is returned. ### TaskForge Base URL: https://qaegxjxaavxdqihfgzhr.supabase.co/functions/v1/taskforge-x402-gateway OpenAPI: https://qaegxjxaavxdqihfgzhr.supabase.co/functions/v1/taskforge-x402-gateway/openapi.json - Machine Service Health Report ($0.10 per call): POST https://qaegxjxaavxdqihfgzhr.supabase.co/functions/v1/taskforge-x402-gateway/MACHINE_SERVICE_HEALTH_REPORT — Reachability, latency and status for a service - Catalog Endpoint Health Audit ($0.25 per call): POST https://qaegxjxaavxdqihfgzhr.supabase.co/functions/v1/taskforge-x402-gateway/CATALOG_ENDPOINT_HEALTH_AUDIT — Check up to 100 catalog endpoints - MCP Security & Permission Audit ($0.25 per call): POST https://qaegxjxaavxdqihfgzhr.supabase.co/functions/v1/taskforge-x402-gateway/MCP_SECURITY_PERMISSION_AUDIT — Before connecting an MCP server - AI Agent Permission Audit ($0.25 per call): POST https://qaegxjxaavxdqihfgzhr.supabase.co/functions/v1/taskforge-x402-gateway/AGENT_PERMISSION_AUDIT — Classify an agent's tools before deployment - CI/CD Supply-Chain Audit ($0.25 per call): POST https://qaegxjxaavxdqihfgzhr.supabase.co/functions/v1/taskforge-x402-gateway/CICD_SUPPLY_CHAIN_AUDIT — Before merging or releasing code - x402 Commerce Integrity Audit ($0.25 per call): POST https://qaegxjxaavxdqihfgzhr.supabase.co/functions/v1/taskforge-x402-gateway/X402_COMMERCE_INTEGRITY_AUDIT — Verify an x402 endpoint before sending buyers - Release Readiness Workflow Audit ($0.50 per call): POST https://qaegxjxaavxdqihfgzhr.supabase.co/functions/v1/taskforge-x402-gateway/RELEASE_READINESS_WORKFLOW_AUDIT — Blocking signals before production - Agent Stack Security Audit ($0.75 per call): POST https://qaegxjxaavxdqihfgzhr.supabase.co/functions/v1/taskforge-x402-gateway/AGENT_STACK_SECURITY_AUDIT — Full agent stack review ### ProofForge Base URL: https://tpnvisfsoateycjrkrie.supabase.co/functions/v1/proofforge-x402 - Claim Check ($0.01 per call): POST https://tpnvisfsoateycjrkrie.supabase.co/functions/v1/proofforge-x402/claim-check — Does the evidence support the claim? - Source Freshness ($0.05 per call): POST https://tpnvisfsoateycjrkrie.supabase.co/functions/v1/proofforge-x402/source-freshness — Is the evidence current enough? - Source Corroboration ($0.10 per call): POST https://tpnvisfsoateycjrkrie.supabase.co/functions/v1/proofforge-x402/source-corroboration — Do multiple sources agree? - Contradiction Scan ($0.25 per call): POST https://tpnvisfsoateycjrkrie.supabase.co/functions/v1/proofforge-x402/contradiction-scan — Does any evidence conflict with the claim? - Artifact Integrity ($0.25 per call): POST https://tpnvisfsoateycjrkrie.supabase.co/functions/v1/proofforge-x402/artifact-integrity — Hash and version checks - Provenance Trace ($0.50 per call): POST https://tpnvisfsoateycjrkrie.supabase.co/functions/v1/proofforge-x402/provenance-trace — Where the evidence came from - Evidence Completeness ($0.50 per call): POST https://tpnvisfsoateycjrkrie.supabase.co/functions/v1/proofforge-x402/evidence-completeness — What evidence is missing - Change Verification ($1.00 per call): POST https://tpnvisfsoateycjrkrie.supabase.co/functions/v1/proofforge-x402/change-verification — Before/after observations - Multi-Source Proof ($2.00 per call): POST https://tpnvisfsoateycjrkrie.supabase.co/functions/v1/proofforge-x402/multi-source-proof — Independent-source agreement - Evidence Confidence Score ($2.00 per call): POST https://tpnvisfsoateycjrkrie.supabase.co/functions/v1/proofforge-x402/evidence-confidence-score — Scored confidence with method - Proof Pack ($5.00 per call): POST https://tpnvisfsoateycjrkrie.supabase.co/functions/v1/proofforge-x402/proof-pack — Bundle of core checks - Deep Verification Pack ($10.00 per call): POST https://tpnvisfsoateycjrkrie.supabase.co/functions/v1/proofforge-x402/deep-verification-pack — Every check with methods and limits ### A.C.E.

Black Knight Technology builds audit, evidence-verification and assurance APIs for AI agents and automated systems: TaskForge (security and reliability audits), ProofForge (evidence verification) and A.C.E. (assurance checks), available pay-per-call over x402 and through API, OEM and white-label licensing, plus ZEI (checkout and subscription integrity scans), offered as pilots and enterprise licenses. - Who is behind Black Knight Technology? Black Knight Technology is an assumed name (d/b/a) of Black Knight Transportation LLC, a Texas limited liability company. It is not affiliated with Black Knight, Inc. Contact: operations@blackknightstech.com. - Can I license or white-label the APIs? Yes. TaskForge, ProofForge, A.C.E. and ZEI can be licensed for volume use, embedded through OEM agreements or offered under your brand through white-label agreements. Terms are set in a written agreement; request one through Contact Sales. - What does ZEI check? ZEI scans checkout, sign-up and cancellation pages for hidden renewal terms, pre-ticked paid extras, missing prices and cancellation that is harder than signing up, and returns Ready, Conditional or Blocked with evidence and fixes. It is in pilot; request a scan or license through Contact Sales. ZEI findings are not legal advice. - How do I call a Black Knight API without an account? Send a POST request to the endpoint. It replies with HTTP 402 Payment Required and the price. Pay it with an x402 client in USDC on the Base network and the result is returned. No account or API key is needed. - What is x402? x402 is an open payment protocol that uses the HTTP 402 status code so software and AI agents can pay for an API call per request, typically in USDC stablecoin, without signing up for an account. - How much do the APIs cost? Prices are per call and range from $0.01 (ProofForge Claim Check, A.C.E. Part Identity Resolver) to $10 (ProofForge Deep Verification Pack). TaskForge audits cost $0.10 to $0.75. Every endpoint and price is listed on the APIs page. - What can TaskForge audit? TaskForge checks MCP servers, AI agent permissions, CI/CD pipelines, x402 payment endpoints, API catalog endpoint health and release readiness. Only audit systems you own or are authorized to assess. - Are the results legal advice or a certification? No. Results are technical decision support based on the evidence supplied and observed at the time of the request. They are not legal advice, a security certification or a guarantee. ## Pages - [APIs and prices](https://blackknightstech.com/apis) - [Licensing](https://blackknightstech.com/licensing) - [Contact sales](https://blackknightstech.com/contact) - [Partner program](https://blackknightstech.com/partners) - [Terms of Service](https://blackknightstech.com/terms) - [Privacy Policy](https://blackknightstech.com/privacy)
