OpenClaw API Contract (v1)

Status: normative Version: 1.0.7 Date: 2026-04-24

This document defines the public API contract for OpenClaw. It serves as the authoritative baseline for client compatibility and breaking change policies.

0. Tenant Boundary Context (S49)

Default behavior remains single-tenant compatible (tenant_id=default).

When OPENCLAW_MULTI_TENANT_ENABLED=1:

• tenant context may be supplied by token context and/or request header (X-OpenClaw-Tenant-Id, configurable)
• token/header mismatch is rejected with 403 (tenant_mismatch)
• connector installation resolution is tenant-scoped and rejects cross-tenant matches fail-closed (diagnostic conflict path)
• current admin/API handlers keep compatibility behavior by defaulting missing tenant context to default tenant

1. Route Inventory

All new integrations should use the /openclaw/ prefix. Use of /moltbot/ is deprecated.

1.0 UI Entry Points

Base Path: /openclaw/

Method	Path	Legacy Path	Auth	Description
GET	/admin	/moltbot/admin	None*	Standalone remote admin console HTML shell (mobile-friendly).

* The page shell can be loaded directly, but all backend write operations from the console still enforce Admin token and remote-admin policy.

1.1 Core Observability & System

Base Path: /openclaw/

Method	Path	Legacy Path	Auth	Description
GET	/health	/moltbot/health	None	System status, uptime, and dependencies.
GET	/capabilities	/moltbot/capabilities	None	Feature flags and supported extensions (includes optional UX/runtime features such as assist streaming support).
GET	/logs/tail	/moltbot/logs/tail	Observability	Tail recent log lines (rate-limited).
GET	/trace/{prompt_id}	/moltbot/trace/{id}	Observability	Get execution trace by prompt ID.
GET	/events	/moltbot/events	Observability	List recent job lifecycle events (JSON polling fallback; includes pagination/scan diagnostics).
GET	/events/stream	/moltbot/events/stream	Observability	SSE stream of job lifecycle events with resume support.
GET	/config	/moltbot/config	Observability	Read-only view of sanitized provider config.
PUT	/config	/moltbot/config	Admin	Update system configuration.
GET	/jobs	/moltbot/jobs	Observability	List recent jobs (Stub/Not Implemented).
GET	/preflight/inventory	/moltbot/preflight/inventory	Admin	Snapshot-first inventory of nodes/models for operator diagnostics, including refresh-state metadata.

Reasoning-content redaction contract:

• operator-visible trace and events payloads strip provider reasoning / thinking-like fields by default
• privileged reveal is opt-in only and requires:
  • request header X-OpenClaw-Debug-Reveal-Reasoning: 1 or query debug_reasoning=1
  • server-side enablement via OPENCLAW_DEBUG_REASONING_REVEAL=1
  • admin authorization
  • loopback source
  • non-hardened runtime profile
  • deployment profile local or lan
• clients MUST treat reveal behavior as debug-only and MUST NOT depend on reasoning payload presence in normal operation

Inventory diagnostics contract:

• /preflight/inventory is snapshot-first and may return before deep scan work finishes
• clients SHOULD treat snapshot_ts, scan_state, stale, and last_error as first-class diagnostics fields rather than assuming a blocking full-rescan model

1.2 Webhooks & Triggers

Auth: Requires configured webhook secret or Admin Token.

Method	Path	Legacy Path	Auth	Description
POST	/webhook	/moltbot/webhook	Webhook Secret	Receive external alerts (schema validation only).
POST	/webhook/submit	/moltbot/webhook/submit	Webhook Secret	Validate and submit job from webhook payload.
POST	/webhook/validate	/moltbot/webhook/validate	Webhook Secret	Dry-run validation of webhook payload.
POST	/triggers/fire	/moltbot/triggers/fire	Admin	Fire an ad-hoc workflow trigger from external system.

1.3 Assist, LLM & Chat

Assist Base Path: /openclaw/assist/

Method	Path	Legacy Path	Auth	Description
GET	/assist/planner/profiles	/moltbot/assist/planner/profiles	Admin/Local	List active planner profiles from registry for UI/node alignment.
POST	/assist/planner	/moltbot/assist/planner	Admin/Local	Planner structured prompt generation.
POST	/assist/refiner	/moltbot/assist/refiner	Admin/Local	Prompt refinement with optional image context.
POST	/assist/planner/stream	/moltbot/assist/planner/stream	Admin/Local	Optional SSE-style planner streaming response (text/event-stream) with staged progress + final payload.
POST	/assist/refiner/stream	/moltbot/assist/refiner/stream	Admin/Local	Optional SSE-style refiner streaming response (text/event-stream) with staged progress + final payload.

Assist payload redaction contract:

• structured assist responses preserve final operator-visible answer fields but strip provider reasoning / chain-of-thought style fields by default
• when the privileged reveal gate is allowed, debug reasoning is exposed only in a separate debug payload and not merged back into the normal structured answer fields

1.3B Connector Installation Diagnostics

Base Path: /openclaw/connector/ Auth: Admin Token Required

Method	Path	Legacy Path	Auth	Description
GET	/connector/installations	/moltbot/connector/installations	Admin	List redacted connector installations with lifecycle diagnostics.
GET	/connector/installations/{installation_id}	/moltbot/connector/installations/{installation_id}	Admin	Get one redacted connector installation record.
GET	/connector/installations/resolve	/moltbot/connector/installations/resolve	Admin	Run fail-closed workspace resolution diagnostics (platform, workspace_id).
GET	/connector/installations/audit	/moltbot/connector/installations/audit	Admin	List installation lifecycle audit evidence (redacted).
GET	/connector/extraction-contract	/moltbot/connector/extraction-contract	Admin	Get the machine-readable connector extraction recommendation, seam families, and current blockers.

Connector diagnostics contract notes:

• installation records may expose operator-safe health metadata under installation.metadata.health (for example ok, invalid_token, revoked, degraded) without exposing token material
• /connector/installations diagnostics may include aggregate health_counts in addition to lifecycle status_counts
• /connector/installations/resolve may expose a stable health_code alongside the legacy reject_reason so clients can distinguish workspace_unbound vs token-health failures without parsing status text
• /connector/extraction-contract is structural packaging metadata only; clients MUST NOT treat it as a live installation-health or token-status feed

1.3C Model Management & Installations

Base Path: /openclaw/ Auth: Admin Token Required

Method	Path	Legacy Path	Auth	Description
GET	/models/search	/moltbot/models/search	Admin	Search normalized model entries across managed installs and catalog sources.
POST	/models/downloads	/moltbot/models/downloads	Admin	Create a managed model download task with progress/cancel lifecycle.
GET	/models/downloads	/moltbot/models/downloads	Admin	List model download tasks with snapshot or delta cursor semantics (since_seq).
GET	/models/downloads/{task_id}	/moltbot/models/downloads/{task_id}	Admin	Get one model download task by id.
POST	/models/downloads/{task_id}/cancel	/moltbot/models/downloads/{task_id}/cancel	Admin	Cancel a queued or running model download task.
POST	/models/import	/moltbot/models/import	Admin	Import a completed managed download into the bounded install root after provenance and hash verification.
GET	/models/installations	/moltbot/models/installations	Admin	List managed model installations.

Model-manager contract notes:

• /models/downloads supports since_seq cursor polling and may return deterministic delta metadata (requested_since_seq, effective_since_seq, next_since_seq, truncation/reset hints) alongside the task list
• download creation requires structured provenance metadata (publisher, license, source_url) and a 64-char expected_sha256
• import keeps fail-closed destination/filename validation and re-checks the staged file hash before activation

1.3D LLM Management & Chat

LLM Base Path: /openclaw/llm/

Method	Path	Legacy Path	Auth	Description
POST	/chat	/moltbot/llm/chat	Admin/Local	Unified chat interface for assistant interactions.
POST	/test	/moltbot/llm/test	Admin	Test LLM connectivity and configuration.
GET	/models	/moltbot/llm/models	Admin	List available models from configured provider. Request-time fetch uses the same SSRF contract as saved base_url validation, including the explicit insecure override for private-IP/HTTP targets.

1.4 Templates & Assets

2. Status & Error Semantics

API responses MUST adhere to the following status codes and envelope format.

2.1 Standard Envelope

All JSON responses (success or error) share a common structure:

{
  "ok": boolean,
  "error": "string (optional)",
  "detail": "string (optional)",
  "trace_id": "string (optional)",
  "data": { ... } // Success payload
}

2.2 Status Codes

Code	Meaning	Usage
200	OK	Successful synchronous request.
201	Created	Resource created (schedules, presets).
202	Accepted	Async job submitted (pending execution or approval).
400	Bad Request	Schema validation failure, missing required fields.
401	Unauthorized	Missing or invalid authentication token.
403	Forbidden	Authenticated but permission denied (e.g., admin-only).
404	Not Found	Resource or route does not exist.
409	Conflict	Idempotency collision or state conflict.
413	Payload Too Large	Input size exceeds OPENCLAW_MAX_RENDERED_WORKFLOW_BYTES or similar limits.
429	Too Many Requests	Rate limit or Execution Budget exceeded.
500	Internal Error	Unhandled server exception.
503	Unavailable	Feature disabled or service not wired.

Tenant-boundary error notes:

• tenant boundary violations use 403 with explicit codes such as tenant_mismatch and tenant_invalid.

2.3 SSE Endpoint Notes (Contractual Behavior)

• SSE endpoints return Content-Type: text/event-stream.
• Current SSE surfaces include:
  • /openclaw/events/stream (job lifecycle events)
  • optional /openclaw/assist/planner/stream and /openclaw/assist/refiner/stream (assist incremental preview path)
• Assist streaming emits event types from the following set:
  • ready
  • stage
  • delta
  • final
  • error
  • keepalive
• Clients MUST treat final as the source of truth for structured assist results. delta preview text is best-effort and may be truncated or differ from the final parsed payload.
• Event-stream and polling payloads redact provider reasoning / thinking traces by default; reveal is debug-only and gated by the same privileged local-debug contract used by trace/assist surfaces.
• Clients SHOULD gracefully fall back to non-streaming assist endpoints when streaming capability is absent or streaming transport fails.

2.4 Pagination & Scan Diagnostics (Management Query Contract)

• GET /openclaw/events and GET /openclaw/approvals include deterministic pagination normalization.
• Responses may include pagination and scan diagnostic objects so clients/operators can detect:
  • normalized limit/offset/cursor values
  • stale/future cursor resets
  • bounded scan truncation or malformed-record skips
• GET /openclaw/preflight/inventory may return snapshot-state diagnostics so clients/operators can detect:
  • whether the response came from a previous cached snapshot
  • whether a background refresh is currently running
  • whether the current snapshot is stale or the last deep scan failed
• Backend/runtime errors outside pagination normalization are still surfaced explicitly (not silently swallowed).

3. Limits & Budgets

These limits are contractual and strictly enforced. Clients MUST handle 413 and 429 responses.

Limit	Metric	Default	Configuration Key
Concurrency (Global)	In-flight jobs	2	OPENCLAW_MAX_INFLIGHT_SUBMITS_TOTAL
Concurrency (Webhook)	In-flight jobs	1	OPENCLAW_MAX_INFLIGHT_SUBMITS_WEBHOOK
Concurrency (Bridge)	In-flight jobs	1	OPENCLAW_MAX_INFLIGHT_SUBMITS_BRIDGE
Concurrency (Per-Tenant)	In-flight jobs per tenant	1	OPENCLAW_MAX_INFLIGHT_SUBMITS_PER_TENANT
Payload Size	Rendered workflow	512KB	OPENCLAW_MAX_RENDERED_WORKFLOW_BYTES
Webhook Body	Raw JSON body	10MB	MAX_BODY_SIZE (internal constant)
Trigger Inputs	Input variables	32KB	Hardcoded in api/triggers.py
Log Tail	Max lines	500	Hardcoded in api/routes.py
