OpenAPI Specification
openapi: 3.2.0
info:
title: Auxen Headless Models API
version: 1.3.0
description: 'Programmatic API for Auxen: hire and manage AI workers (`/v1/workers`,
`/v1/connections`, approvals; also over MCP and A2A), and deploy and
manage private open-weight model endpoints. Anything a human can do in
the dashboard, an agent can do via this API.
**Two key types:**
- `auxen_live_…` / `auxen_test_…` — your account-level **agent management**
key. Authorizes deploying, switching models, and billing operations.
- `auxk_…` — a per-deployment **inference** key returned in the `api_key`
field of every deployment object. Authorizes inference calls on that
deployment only. Hand it to downstream services without giving up
management rights.
**Billing:**
All Auxen deployments are billed **pay-as-you-go** from a prepaid USD credit
balance, per minute of active time; billing stops when a deployment is
paused or deleted. Throughput levels (Standard, Double, Quad, Max)
increase simultaneous request handling at the same model quality. Top up
the balance with `POST /v1/billing/add-credits`.
**2026 renames:** `/v1/provision` → `/v1/deploy`, `/v1/instances` →
`/v1/deployments`, `/scale` → `/throughput`, `/wake` → `/resume`.
Old routes keep working until 2027-04-02 and send `Deprecation`,
`Sunset`, and `Link` headers. Responses carry new and old field names
side by side (`deployment_id` + `instance_id`, `throughput` +
`capacity`, `rate_per_hour` + `hourly_rate`, `ready_estimate` +
`estimated_ready_at`). Migration guide: https://auxen.ai/docs/api/migration'
