API reference

API overview

Mobius exposes a JSON HTTP API at https://api.mobius.deepnoodle.ai. Every endpoint is versioned under /v1.

Authentication

All requests require an API key in the Authorization header:

Authorization: Bearer mob_sk_abc123

API keys are scoped to a single organization and can optionally be pinned to a single project. Generate them under Settings → API Keys.

Pagination — list endpoints use cursor-based pagination via cursor and limit query parameters. Cursors are opaque base64url strings.
IDs — every resource has a typed ID prefix (run_, wf_, wkr_, etc.) so you can tell at a glance what kind of thing you're holding.
Errors — non-2xx responses include a JSON body with code, message, and details fields.
Webhook terminology — /v1/projects/{handle}/webhooks is the managed inbound webhook resource, /v1/billing/webhook is a billing-specific inbound Stripe receiver, and workflow callback_url refers to an outbound callback concept. See Webhooks.
