API

WEDNESDAY exposes a production HTTP service at https://api.wednesdaychat.com. This documentation publishes the supported external contract without treating every internal service route as public API.

Production origin

https://api.wednesdaychat.com

The web product and supported WEDNESDAY clients use this origin for durable product operations. The API is designed around account-authorized state, streaming execution, projects, files, search, research, sharing, and related platform workflows.

Access model

Most product operations require a valid WEDNESDAY account session and derive durable ownership from server-authorized account state. Do not fabricate owner identifiers or infer a general third-party API-key program from browser/client transport details.

Start with Authentication before integrating a protected route.

Reference

Use the API reference for the deliberately published HTTP surface. The reference currently includes verified system, search, project, conversation, chat, file, and artifact capability boundaries while withholding privileged, provider-callback, administrative, and implementation-only routes.

Errors and protection

• Errors documents stable HTTP failure classes and retry guidance.
• Rate limits documents 429, Retry-After, fail-closed protection, and quota publication policy.
• Production best practices covers durable-state reconciliation, streaming, readiness, security, and release discipline.

Contract policy

Public documentation is a compatibility promise. An endpoint, header, provider model, internal module, or telemetry label found in source code is not automatically public API. WEDNESDAY publishes only the behavior it intends developers to depend on.
