Gateway

The v1 gateway routes incoming requests to registered plugins. It supports three payment methods — Stripe (existing), MPP (Machine Payments Protocol) via the Tempo blockchain, and session-based billing for low-latency, off-chain per-call payments.

Base URL

POST /api/v1/gateway

Request

Headers

Header	Type	Required	Description
`Content-Type`	string	Yes	Must be `application/json`
`X-Plugin-Id`	string	No	Plugin to route the request to. Overrides the `plugin` field in the body.
`X-Payment-Method`	string	No	Payment method to use: `stripe`, `mpp`, or `session`. Defaults to `stripe`.
`Authorization`	string	No	For MPP payments, use `Payment <credential>`. For session auth, handled via cookies.
`X-Session-Id`	string	No	Active session ID for session-based billing. Required when `X-Payment-Method` is `session`.
`X-Wallet-Address`	string	No	Wallet address that owns the session (0x-prefixed). Required when `X-Payment-Method` is `session`.
`Accept`	string	No	Set to `text/event-stream` for streaming responses (where supported).

Body

{
  "plugin": "agent",
  "messages": [{ "role": "user", "content": "Hello" }]
}

Field	Type	Required	Description
`plugin`	string	No	Plugin ID to route to. The `X-Plugin-Id` header takes priority if both are provided. Defaults to `agent`.

Additional body fields are forwarded to the target plugin.

Plugins

The gateway routes to the following plugins:

Plugin ID	Name	Description	Auth required	Streaming
`agent`	Agent	Agent orchestrator for multi-step tasks	No	Yes
`generate-text`	Text Generation	LLM text generation	No	Yes
`tts`	Text-to-Speech	Speech synthesis	No	No
`stt`	Speech-to-Text	Speech transcription	No	No

agent is the default plugin when no plugin ID is specified.

Authentication

No plugins currently require authentication. The gateway checks whether a plugin has its auth flag enabled — since no built-in plugin sets this flag, all requests are processed without requiring a session, MPP credential, or payment session. If a custom plugin is registered with auth: true, the gateway enforces either a valid session (cookie-based via NextAuth), a verified MPP payment credential, or an active payment session. If you pay with MPP or use session-based billing, cookie-based authentication is not required for auth-enabled plugins.

Payment flow

The gateway supports three payment methods per request:

Stripe — Default. Requires an active subscription or credits. See Stripe integration.
MPP — Crypto-native payments on the Tempo blockchain. See MPP payments.
Session — Off-chain, per-call billing using a pre-funded payment session. See MPP payments — sessions and the wallet sessions API.

The server selects the payment method using the following priority:

X-Payment-Method header (session, mpp, or stripe)
Presence of an Authorization: Payment header (implies mpp)
Default: stripe

MPP 402 challenge

When an MPP request has no valid credential, the gateway returns 402 Payment Required with pricing information for both payment methods:

{
  "error": "payment_required",
  "message": "Payment required for agent. Choose payment method: Stripe or Tempo MPP.",
  "mpp": {
    "scheme": "Payment",
    "amount": "0.05",
    "currency": "0x20c0000000000000000000000000000000000000",
    "recipient": "0xd8fd0e1dce89beaab924ac68098ddb17613db56f",
    "description": "Agent orchestrator request",
    "nonce": "a1b2c3d4e5f6...",
    "expiresAt": 1742472000000
  },
  "stripe": {
    "checkoutUrl": "/api/v1/payments/stripe/create?plugin=agent",
    "amount": "0.05",
    "currency": "usd"
  }
}

The WWW-Authenticate header is also set:

Payment amount="0.05", currency="0x20c0000000000000000000000000000000000000", recipient="0xd8fd0e1dce89beaab924ac68098ddb17613db56f"

Session-based billing

When X-Payment-Method is session, the gateway auto-debits the caller’s payment session using an off-chain voucher. This avoids the 402 challenge/response round-trip and settles each call in sub-100ms. To use session-based billing:

Open a payment session via POST /api/wallet/sessions. See wallet sessions.
Include X-Session-Id and X-Wallet-Address headers on every gateway request.
The gateway looks up the session, verifies the balance covers the plugin price, and debits the session automatically.
The response includes a Payment-Receipt header with the voucher reference and an X-Session-Remaining header with the updated balance.

If the session is missing, expired, or has insufficient balance, the gateway returns 402 with a descriptive error. See error responses for the full list of session-related error codes.

Response

Success (200)

{
  "plugin": "agent",
  "message": "Request processed by agent plugin",
  "timestamp": "2026-03-20T03:33:15.000Z",
  "payment": {
    "method": "stripe",
    "receipt": null
  }
}

When paid via MPP, the response includes a Payment-Receipt header and the payment.receipt field contains the transaction hash. When paid via a session, the payment.receipt field contains the voucher reference (formatted as session:<sessionId>:<nonce>).

Response headers

Header	Description
`x-plugin-id`	The plugin that handled the request
`Payment-Receipt`	Payment receipt. For MPP: transaction hash. For sessions: voucher reference (`session:<sessionId>:<nonce>`). Only present for MPP or session-paid requests.

500	`internal`	Internal server error
502	`no_plugin`	No plugin registered for the given ID

Per-agent gateway authentication

Each agent container receives a unique gateway auth token at provisioning time. The internal gateway authenticates requests using token-based auth on port 18789.

Field	Description
`gateway.auth.mode`	`token`
`gateway.auth.token`	Unique hex token auto-generated per container. Provisioning generates a 48-character token (24 bytes of entropy). The container entrypoint generates a 32-character token (16 bytes) if no token is passed via the `OPENCLAW_GATEWAY_TOKEN` environment variable.
`gateway.port`	`18789`

The container entrypoint writes its own minimal configuration to $HOME/.openclaw/openclaw.json using a slightly different schema (auth.method at the top level instead of gateway.auth.mode). The provisioning config written by the backend uses the gateway.auth.mode path. When the entrypoint runs, it overwrites the provisioning config with its own minimal skeleton. To preserve the full provisioning config, pass the gateway token via the OPENCLAW_GATEWAY_TOKEN environment variable so the entrypoint uses the same token.

Agent container configuration

When an agent is provisioned, the backend generates an OpenClaw configuration with the following parameters. These values are set automatically and cannot be overridden by the caller.

Container environment variables

The following environment variables are set on every agent container at launch. Variables are grouped by source — some are set by the container image entrypoint (local Docker path) and others are injected by the provisioning service (Railway path). When both paths set the same variable, the provisioning service value takes precedence.

Variable	Default	Description
`NODE_ENV`	`production`	Node.js environment. Set by the provisioning service.
`PORT`	`18789`	Port the agent process listens on inside the container. Must match the OpenClaw Gateway port. Set by the provisioning service.
`HOME`	`/home/node`	Home directory for the `node` user that the official OpenClaw image runs as
`TERM`	`xterm-256color`	Terminal type
`NODE_COMPILE_CACHE`	`/var/tmp/openclaw-compile-cache`	Directory for the Node.js compile cache. Speeds up cold starts by caching compiled bytecode across process restarts.
`OPENCLAW_NO_RESPAWN`	`1`	When set to `1`, prevents the OpenClaw process from automatically respawning after exit. Container-level restart policies (Docker `--restart` or orchestrator health checks) handle process recovery instead.
`OPENCLAW_GATEWAY_TOKEN`	Auto-generated	Gateway authentication token. When not set, the entrypoint generates a 32-character hex token. See per-agent gateway authentication.
`OPENCLAW_GATEWAY_URL`	Platform URL	Gateway URL for the agent to communicate with the platform gateway. Set by the provisioning service.
`OPENCLAW_GATEWAY_PORT`	`18789`	Port the gateway listens on inside the container
`OPENCLAW_GATEWAY_BIND`	`0.0.0.0`	Bind address for the gateway process. Set to `0.0.0.0` so Railway (and other reverse proxies) can route traffic into the container.
`OPENCLAW_BIND`	`0.0.0.0`	Fallback bind address used when `OPENCLAW_GATEWAY_BIND` is not set.
`AGENTBOT_USER_ID`	Per-user	Owner user ID passed at provisioning time
`AGENTBOT_PLAN`	`solo`	Subscription plan tier (`solo`, `collective`, `label`, or `network`)
`AGENTBOT_API_URL`	`https://agentbot-api.onrender.com`	Backend API URL for the agent to call platform services. Set by the provisioning service.
`AGENTBOT_MODE`	`home`	Installation mode (`home` for self-hosted, `link` for existing OpenClaw)
`AGENTBOT_API_KEY`	Per-user	API key for authenticating with the Agentbot platform
`DATABASE_URL`	Platform-provided	PostgreSQL connection string for agent data persistence. Set by the provisioning service.
`OPENROUTER_API_KEY`	Platform-provided	OpenRouter API key for AI model access. Set by the provisioning service.
`INTERNAL_API_KEY`	Platform-provided	Internal API key for authenticating agent-to-platform requests. Set by the provisioning service.
`WALLET_ENCRYPTION_KEY`	Platform-provided	Encryption key for securing agent wallet data at rest. Set by the provisioning service.

Gateway settings

Parameter	Value	Description
`gateway.bind`	`0.0.0.0`	Bind address for the gateway. On Railway-provisioned containers, the `OPENCLAW_GATEWAY_BIND` environment variable is set to `0.0.0.0` so the gateway listens on all interfaces and Railway’s reverse proxy can route traffic into the container. For local Docker containers, the entrypoint overrides this to `loopback` via the `--bind loopback` CLI flag unless `OPENCLAW_GATEWAY_BIND` is set.
`gateway.port`	`18789`	Internal gateway port
`gateway.auth.mode`	`token`	Authentication mode
`gateway.auth.rateLimit.maxAttempts`	`10`	Maximum authentication attempts before lockout
`gateway.auth.rateLimit.windowMs`	`60000`	Rate limit window in milliseconds (1 minute)

`tools.exec.allowedPaths`	`["~/.openclaw/workspace", "/tmp", "/home/node"]`	Filesystem paths the agent can access. The official OpenClaw image runs as the `node` user (`/home/node`). Configuration is stored at `/home/node/.openclaw/openclaw.json`.
`tools.exec.denyPaths`	`["/etc/shadow", "/etc/passwd", "/proc", "/sys"]`	Filesystem paths the agent is blocked from accessing
`tools.web.maxChars`	`50000`	Maximum characters returned from web tool requests
`tools.loopDetection.maxIterations`	`20`	Maximum loop iterations before the agent is interrupted

`agents.defaults.skipBootstrap`	`false`	Whether to skip the bootstrap phase
`agents.defaults.bootstrapMaxChars`	`4000`	Maximum characters for bootstrap content

Health monitoring

The gateway monitors channel health for each agent container. When a channel becomes unresponsive, the gateway can automatically restart it.

Parameter	Value	Description
`channelHealthCheckMinutes`	`5`	Interval between health checks for each channel
`channelStaleEventThresholdMinutes`	`30`	Channel is considered stale if no events are received within this window
`channelMaxRestartsPerHour`	`10`	Maximum number of automatic channel restarts per hour

CORS

The gateway supports CORS preflight via OPTIONS /api/v1/gateway. Allowed methods are GET, POST, and OPTIONS. The Content-Type, Authorization, X-Plugin-Id, and Payment headers are permitted in the CORS configuration.

The X-Payment-Method, X-Session-Id, and X-Wallet-Address headers are read server-side but are not included in the CORS Access-Control-Allow-Headers response. Cross-origin requests that include these headers may be rejected by the browser preflight check. Same-origin requests are unaffected. If you need to send these headers from a different origin, configure the GATEWAY_CORS_ORIGIN environment variable or proxy the request through a same-origin endpoint.

OpenAI-compatible endpoints

The gateway exposes a set of endpoints that follow the OpenAI API format. These allow you to use Agentbot as a drop-in replacement for the OpenAI SDK or any tool that supports the OpenAI API shape.
