What This Tool Does

A flexible and secure HTTP client designed for agent-driven API integrations and web service interactions. This function supports all standard HTTP methods including GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS, enabling comprehensive RESTful API communication. Users can configure requests with custom headers, query parameters, and request bodies in JSON, plain text, or base64-encoded binary formats. The tool provides four authentication modes: none for public endpoints, basic for username/password credentials automatically encoded to Base64, bearer for OAuth-style token authentication, and header for custom API key or signature-based authentication schemes. Built-in security features include URL validation that blocks private and loopback IP addresses by default (configurable via allow_private), configurable timeouts from 1 to 120 seconds, and response size limits up to 20MB to prevent memory issues. Response handling offers four modes—auto, json, text, and base64—with auto-detection intelligently parsing responses based on content-type headers. The function returns comprehensive response metadata including status code, headers, final URL after redirects, and the parsed body, making it an essential building block for workflows that need to interact with external APIs, webhooks, or web services.

Webhook - HTTP Request

Overview

A general-purpose HTTP client that can make requests to any public URL. Supports all standard HTTP methods, multiple authentication schemes, flexible body formats, and configurable response handling. Use it to call REST APIs, fetch web resources, post webhooks, or interact with any HTTP-based service.

Actions

request

Make an HTTP request to a specified URL.

Required Fields:

• url — the full URL to send the request to (must be http or https)

Optional Fields:

• request_method — HTTP method: GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS (default: GET)
• headers — object of custom HTTP headers (e.g., {"Accept": "application/xml"})
• query_params — object of URL query parameters (e.g., {"page": "2", "limit": "10"})
• body_json — JSON object body (sets Content-Type to application/json automatically)
• body_text — plain text body
• body_base64 — base64-encoded binary body (for file uploads or binary data)
• auth_type — authentication scheme: "none", "basic", "bearer", or "header" (default: "none")
• auth_username — username for basic auth (required when auth_type is "basic")
• auth_password — password for basic auth (required when auth_type is "basic")
• auth_token — token for bearer auth (required when auth_type is "bearer")
• auth_header_name — custom header name for header auth (required when auth_type is "header")
• auth_header_value — custom header value for header auth (required when auth_type is "header")
• timeout_seconds — request timeout in seconds, 1-120 (default: 30)
• response_mode — how to return the response body: "auto", "json", "text", "base64" (default: "auto")
• max_response_bytes — maximum response size in bytes, 1024-20971520 (default: 1048576 / 1 MB)
• allow_private — set to true to allow requests to private/loopback IPs (default: false)

Note: Only one body field can be used per request (body_json, body_text, or body_base64).

Example — Simple GET request:

{
  "action": "request",
  "request_method": "GET",
  "url": "https://api.example.com/data",
  "query_params": {"format": "json"}
}

Example — POST with JSON body:

{
  "action": "request",
  "request_method": "POST",
  "url": "https://api.example.com/items",
  "headers": {"X-Custom-Header": "my-value"},
  "body_json": {"name": "Widget", "quantity": 5}
}

Example — Bearer token authentication:

{
  "action": "request",
  "request_method": "GET",
  "url": "https://api.example.com/protected/resource",
  "auth_type": "bearer",
  "auth_token": "eyJhbGciOiJIUzI1NiIs..."
}

Example — Basic authentication:

{
  "action": "request",
  "request_method": "GET",
  "url": "https://api.example.com/account",
  "auth_type": "basic",
  "auth_username": "myuser",
  "auth_password": "mypassword"
}

Example — Custom header authentication (API key):

{
  "action": "request",
  "request_method": "GET",
  "url": "https://api.example.com/v2/search",
  "auth_type": "header",
  "auth_header_name": "X-API-Key",
  "auth_header_value": "abc123def456"
}

Example — PUT to update a resource:

{
  "action": "request",
  "request_method": "PUT",
  "url": "https://api.example.com/items/42",
  "body_json": {"name": "Updated Widget", "quantity": 10}
}

Example — DELETE a resource:

{
  "action": "request",
  "request_method": "DELETE",
  "url": "https://api.example.com/items/42"
}

Example — Get binary response as base64:

{
  "action": "request",
  "request_method": "GET",
  "url": "https://example.com/image.png",
  "response_mode": "base64"
}

Response Format

Successful requests return:

• status_code — HTTP status code (e.g., 200, 404)
• headers — response headers as an object
• content_type — the Content-Type header value
• url — the final URL (after any redirects)
• body_json, body_text, or body_base64 — response body in the format determined by response_mode

Common Workflows

1. Call a REST API — Use GET/POST/PUT/DELETE with body_json and auth_type to interact with any REST service.
2. Send a webhook — POST a JSON payload to a webhook URL to trigger external automations.
3. Fetch a web page — GET any public URL and receive the HTML as text.
4. Download binary content — GET a file URL with response_mode: "base64" to receive binary data encoded for further processing.
5. Check endpoint availability — Use HEAD or OPTIONS to verify a service is reachable without downloading the full response body.

Important Notes

• Only http and https URLs are supported.
• Requests to private or loopback IP addresses are blocked by default. Set allow_private to true to override.
• Only one body type can be provided per request. Supplying more than one of body_json, body_text, or body_base64 will cause an error.
• When response_mode is "auto", JSON responses are parsed automatically; otherwise text is returned, or base64 for binary content.
• Responses exceeding max_response_bytes will be rejected. Increase the limit (up to ~20 MB) for larger payloads.
• The maximum timeout is 120 seconds.

  "action": "get_instructions",
  "tool_id": "webhook-http-request"
}

Response Handling

• Treat the returned JSON as the source of truth for this tool call.
• If the response includes warnings or correction targets, apply them before retrying.
• If the response includes a passed or success-style boolean, use it as the workflow gate.
• If validation fails or the response shape is unclear, call get_schema or get_instructions before retrying.
• If request fails, preserve the request parameters and retry only after fixing schema, auth, or payment errors.

Security

• Do not place account secrets, wallet private keys, mnemonics, signatures, or payment headers in prompts or logs.
• Keep tool inputs scoped to the minimum content needed for the task.
• Use the setup skills for credential handling; this product skill only defines product-specific behavior.
