projectpermit-api-v2-production.up.railway.app

Municipal construction permit preflight for supported Canadian cities. Use it when proposed renovation/building work needs an evidence-linked permit-applicability check before quoting, scheduling or design lock. Start with projectpermit_info to discover supported jurisdiction ids, project families and valid examples. Normalize the proposed scope into structured facts before calling check_project_requirements, or use check_project_requirements_batch for up to 50 normalized projects. Results include deterministic workflow guidance plus a platform-neutral action_bundle containing decision/routing, proposed tasks, official evidence, audit metadata, deterministic decision identity, duplicate-suppression idempotency and a safe writeback mutation gate. For repeated checks of the same work record, pass the prior action_bundle.identity as context.prior_decision_identity to receive change.classification and NOOP_UNCHANGED when appropriate. A READY mutation gate does not execute a write; an authorized integration must still explicitly request an atomic upsert by idempotency_key. Preserve unknown facts rather than guessing them; the engine can return review or municipal-confirmation states when the facts do not support a safe yes/no. Do not use ProjectPermit as municipal authorization, legal advice, engineering review, plan/code review, permit filing or inspection approval.
