CodeBuddy Code HTTP API Beta ​

Beta: This API is in Beta. Interfaces may be adjusted. Feedback is welcome.

CodeBuddy Code provides two public interface sets for developers building Agent applications:

  • REST API (/api/v1/*) — Stateless HTTP request/response, suitable for webhook integration, management operations, and simple queries
  • ACP (/api/v1/acp) — Stateful streaming protocol (JSON-RPC over SSE), suitable for building full Agent client applications

Quick Start ​

Starting the HTTP Service ​

bash
codebuddy --serve --port 8080 --session-id my-session

API Documentation (Swagger UI) ​

Once the service is running, visit:

  • Interactive docs: http://127.0.0.1:8080/api/docs
  • OpenAPI spec: http://127.0.0.1:8080/api/openapi.json

Swagger UI provides an interactive testing interface for all public endpoints.

Verify the Service ​

bash
curl http://127.0.0.1:8080/api/v1/health
# {"data":{"status":"ok","uptime":12.3,"platforms":["generic","wecom","wechat-kf"]}}

Security ​

Custom Request Header ​

All API requests (except exempt paths) must include the custom request header:

X-CodeBuddy-Request: 1

Rationale: A custom request header makes cross-origin browser requests "non-simple requests", forcing a CORS preflight. Combined with a CORS allowlist, requests from unauthorized origins are blocked. Even if an attacker uses fetch(url, { mode: 'no-cors' }), browsers do not allow custom headers in no-cors mode, so the request is rejected by the server (403) due to the missing header.

Exempt Paths ​

The following paths do not require the X-CodeBuddy-Request header:

PathDescription
GET /SPA entry page
GET /assets/*Static assets
GET /docs/*API documentation pages
GET /manifest.webmanifestPWA manifest
GET /api/v1/auth/statusAuthentication status check
POST /api/v1/auth/loginLogin
*/api/v1/webhooks/*Webhooks (verified by platform signature)
GET /api/openapi.jsonOpenAPI spec
GET /api/docs*Swagger UI

This validation can be disabled via the environment variable CODEBUDDY_DISABLE_REQUEST_VALIDATION=1.

CORS Allowlist ​

Cross-origin request Origin headers are matched against the server's CORS allowlist. Sources not on the allowlist are rejected (preflight returns 204 without CORS headers; actual requests return 403 Origin not allowed). Allowlist sources:

  • Local endpoint's own loopback variants (localhost / 127.0.0.1 / [::1], only for the port the service is actually listening on)
  • Tunnel URL (if enabled)
  • Configuration item gateway.corsOrigins
  • Environment variable CODEBUDDY_CODE_CORS_ORIGINS (comma-separated, supports exact origin, *.domain subdomain wildcards, and * for all)

⚠️ Loopback origins are no longer unconditionally allowed. The earlier implementation allowed any localhost / 127.0.0.1 origin (regardless of port), which meant any page occupying a local port in the user's browser (e.g., a malicious page running at http://localhost:3000) could cross-origin call this service's process execution / file read-write interfaces. Cookie SameSite=Strict cannot protect against this scenario — ports are not part of a "site", localhost:3000 and localhost:8321 are same-site different-origin, and the browser will carry the session Cookie as usual.

Local development (Vite dev server 5173 → backend 8321 is cross-origin) requires explicitly declaring the origin:

bash
CODEBUDDY_CODE_CORS_ORIGINS=http://localhost:5173 codebuddy --serve

When rejected, both the server logs and the hint field in the 403 response body will suggest this configuration.

When binding to 0.0.0.0 (e.g., --host 0.0.0.0, common in cloud VM / LAN exposure scenarios), if CODEBUDDY_CODE_CORS_ORIGINS is not explicitly set, the server automatically allows all origins (equivalent to configuring *), enabling access to the Web UI via any IP or domain without additional configuration. When this environment variable is explicitly set, the user configuration takes precedence. In this scenario, authentication is forcibly enabled (see below), and credentials are still required.

Authentication ​

--serve enables password authentication by default. On first startup, a random password is generated and written to ~/.codebuddy/settings.json, and a clickable link with the password is printed in the terminal:

  Endpoint    http://127.0.0.1:8321
  Web UI      http://127.0.0.1:8321/?password=<generated-password>

  Password    <generated-password>
  Config      ~/.codebuddy/settings.json

Click the link to log in to the Web UI (the server issues a gateway_session Cookie valid for 30 days; subsequent direct access to the endpoint requires no re-entry).

Authentication mode priority (high → low):

SourceValueDescription
Environment variable CODEBUDDY_GATEWAY_AUTHpassword / noneHighest priority, suitable for CI
Bound to non-loopback address (e.g., --host 0.0.0.0)Forced passwordCannot be disabled when exposed externally
Command-line --auth <mode>password / none
Configuration item gateway.authpassword / none
Default valuepasswordFallback mode for --serve

Security note: These endpoints include sensitive capabilities such as process execution (/api/v1/process/*), arbitrary file read/write (/api/v1/files/*, /api/v1/fs/*), and interactive terminal (/api/v1/pty/*). Therefore, authentication is enforced by default (secure by default, consistent with E2B Secured Access default behavior). Disabling authentication means any process on the same machine can execute commands and read/write files via this service. Only recommended in isolated environments (containers / one-shot sandboxes) or CI.

Disabling authentication (only use when you clearly understand the risks; a warning is printed at startup):

bash
codebuddy --serve --auth none
# or
CODEBUDDY_GATEWAY_AUTH=none codebuddy --serve

Carrying Credentials ​

API requests (/api/v1/*) only accept headers or Cookies:

bash
# 1) Bearer Token (recommended, also carries the security header)
curl -H "X-CodeBuddy-Request: 1" \
     -H "Authorization: Bearer YOUR_PASSWORD" \
     http://host:port/api/v1/sessions

# 2) X-Access-Token (equivalent to Bearer, aligned with E2B envd's credential header convention)
curl -H "X-CodeBuddy-Request: 1" \
     -H "X-Access-Token: YOUR_PASSWORD" \
     http://host:port/api/v1/sessions

# 3) Cookie (automatically carried after browser login)
curl -H "X-CodeBuddy-Request: 1" \
     -H "Cookie: gateway_session=<sha256(password)>" \
     http://host:port/api/v1/sessions

⚠️ ?password= is only valid for GET / and POST /api/v1/auth/login; it has no effect on other /api/v1/* endpoints (returns 401). This is by design: URLs are recorded in browser history, server access logs, and leaked when users copy and share links, so passwords do not appear in API request URLs. The sole purpose of ?password= is the initial entry to obtain the gateway_session Cookie.

Testing APIs with ?password= will return 401 — this is not an authentication implementation issue.

Response Format ​

All /api/v1/* endpoints use a unified envelope format:

jsonc
// Success
{
    "data": { ... }
}

// Error
{
    "error": {
        "code": "AUTH_REQUIRED",      // Machine-readable error code
        "message": "Authentication required"  // Human-readable description
    }
}

Usage Examples ​

The following examples omit the common request headers to highlight each endpoint's own parameters. When actually calling /api/v1/*, you need to include:

-H "X-CodeBuddy-Request: 1" -H "Authorization: Bearer $PASSWORD"

Where $PASSWORD is the password printed at --serve startup (see Authentication). Missing the security header results in 403 Missing required header; missing credentials results in 401 AUTH_REQUIRED. Only /api/v1/health, /api/v1/auth/status, and other exempt endpoints can be accessed directly.

Health Check ​

bash
curl http://127.0.0.1:8080/api/v1/health

Initiate Agent Execution ​

bash
# Send message (body is Gateway Protocol format, id/type required)
curl -X POST http://127.0.0.1:8080/api/v1/runs \
  -H "Content-Type: application/json" \
  -H "X-CodeBuddy-Request: 1" \
  -d '{
    "id": "run-1",
    "type": "message",
    "source": {"platform": "generic", "sender": {"id": "dev", "name": "Developer"}, "conversation": {"id": "run-1", "type": "direct"}},
    "payload": {"text": "Help me analyze code performance"}
  }'

# Response: {"data": {"runId": "uuid-xxx", "status": "accepted"}}

# Get results via SSE stream (also requires X-CodeBuddy-Request header)
curl -H "X-CodeBuddy-Request: 1" http://127.0.0.1:8080/api/v1/runs/uuid-xxx/stream

Request Body Fields (Gateway Protocol) ​

The request body for POST /api/v1/runs uses the Gateway Protocol inbound message format:

FieldRequiredTypeDescription
id✅stringUnique message ID, generated by the caller, used for deduplication and tracing
type✅"message" | "action"Message type. message initiates a conversation, action sends a control command
payload.text—stringPrompt text (also accepts top-level text / prompt)
payload.attachments—arrayAttachment list, elements contain type (image/voice/video/file), url, urlType (local-path/url), etc.
version—stringProtocol version, default "1.0"
source.platform—stringSource platform, default "generic"
source.sender.id—stringSender ID, used for rate limiting; defaults to "unknown"
source.sender.name—stringSender name
source.conversation.id—stringConversation ID, defaults to id
source.conversation.type—"direct" | "group"Conversation type, default "direct"
action—"cancel" | "status"Control action, only used when type="action"
callback.url—stringCallback URL for async result delivery (mode B)
callback.headers—objectCustom headers for the callback request
timeoutMs—numberSingle execution timeout (milliseconds), takes priority over settings.gateway.runTimeoutMs; can also use the X-Codebuddy-Run-Timeout request header. Set to 0 or negative to disable timeout protection

The authoritative definition is in the source code src/node/remote-gateway/gateway-protocol.ts as GatewayInboundMessage.

Settings Management ​

bash
# List all settings
curl http://127.0.0.1:8080/api/v1/settings

# List settings by scope
curl "http://127.0.0.1:8080/api/v1/settings?scope=user"

# Get a single setting
curl http://127.0.0.1:8080/api/v1/settings/model

Workspace Directories ​

Manage attached working directories so that the permission system allows file operations under these directories (same effect as the /add-dir command).

bash
# List current attached working directories
curl http://127.0.0.1:8080/api/v1/workspace-dirs

# Add a working directory
curl -X POST http://127.0.0.1:8080/api/v1/workspace-dirs \
  -H "Content-Type: application/json" \
  -d '{"path": "/Users/me/other-project"}'

# Remove a working directory
curl -X DELETE "http://127.0.0.1:8080/api/v1/workspace-dirs?path=/Users/me/other-project"

# Full sync (call after page refresh recovery)
curl -X PUT http://127.0.0.1:8080/api/v1/workspace-dirs/sync \
  -H "Content-Type: application/json" \
  -d '{"dirs": ["/Users/me/project-a", "/Users/me/project-b"]}'

Notes:

  • Added directories are stored in CLI scope (process memory) and are lost when the instance shuts down
  • The frontend persists them via the Web UI's workspace storage and automatically syncs to the backend on page refresh
  • After adding, Agent tools (Read/Write/Glob/Grep/Bash) can access these directories without asking
