Preview API is live

Stop bad branches before they burn more compute.

A deterministic decision gate for autonomous agents. Evaluate progress, loops, budget, and evidence—then receive a portable, tamper-evident execution receipt.

A checkpoint outside the agent loop.

Internal self-checks share the same context and incentives as the branch they judge. Agent Decision Gate supplies an independent policy boundary and a receipt another runtime can verify.

01 / SUBMIT

Send branch evidence

Progress signals, verified artifacts, cost, tool calls, risk events, authorization budget, and the pinned policy reference.

02 / DECIDE

Get an operational action

Continue, prune, stop, abstain, or escalate—plus reason codes and remediation that a calling agent can execute directly.

03 / VERIFY

Carry the receipt forward

Persist the canonical request, decision, policy, and receipt with a public integrity view and branch-chain verification.

Small surface. Concrete decisions.

Start with one evaluation endpoint. Discovery, pricing, examples, and verification are free machine-readable surfaces.

POST/v1/branches/evaluate

Evaluate a branch and return an action, reason codes, remediation, and receipt. Add ?persist=true for D1/R2 persistence.

POST/v1/receipts/verify

Recompute receipt integrity and, when stored, verify the D1 registration, R2 payload, and previous chain link.

GET/.well-known/agent.json

Canonical machine entry point with absolute links, capabilities, trust boundaries, and integration routes.

GET/v1/openapi.json

OpenAPI 3.1 contract for tool generation, autonomous integration, request validation, and endpoint discovery.

Trust the receipt for what it proves.

The service makes narrow, testable claims. That boundary is part of the product—not a disclaimer hidden after the fact.

It proves

  • The submitted payload produced the recorded deterministic decision.
  • The policy identity and canonical policy hash matched.
  • The persisted receipt payload and chain link remain intact.

It does not prove

  • That every input claim describes real-world truth.
  • That an agent owns a global identity or reputation.
  • That preview-mode calls settled real funds.

Discoverable without a sales call.

Agents can inspect the service, generate a client from OpenAPI, evaluate a branch, and verify the returned receipt using public routes.
