hanzo-tools-api

Generic API tool for calling any REST API via OpenAPI specs.

Features

• Credential Management: Securely store and manage API keys with env var fallback
• OpenAPI Support: Parse OpenAPI 3.x specs to discover and call operations
• Auto-Detection: Automatically detects credentials from environment variables
• Multi-Provider: Built-in support for 30+ cloud providers
• Raw Requests: Make raw HTTP requests when you need more control

Installation

pip install hanzo-tools-api

Quick Start

Using Environment Variables (Recommended)

Set your API keys as environment variables:

export CLOUDFLARE_API_TOKEN=your-token
export GITHUB_TOKEN=ghp_xxx
export STRIPE_API_KEY=sk_xxx

The tool automatically detects these when you make calls.

Using the Tool

from hanzo_tools.api import APITool

tool = APITool()

# List available providers and their status
await tool.call(ctx, action="list")

# Configure a provider manually
await tool.call(ctx, 
    action="config",
    provider="cloudflare",
    api_key="your-key"
)

# Load OpenAPI spec for a provider
await tool.call(ctx, action="spec", provider="cloudflare")

# List available operations
await tool.call(ctx, action="ops", provider="cloudflare", search="zones")

# Call an operation
await tool.call(ctx,
    action="call",
    provider="cloudflare",
    operation="listZones"
)

# Make a raw request
await tool.call(ctx,
    action="raw",
    provider="github",
    method="GET",
    path="/user/repos"
)

API Reference

Actions

• list: Show all providers and their configuration status
• config: Set credentials for a provider
• delete: Remove credentials for a provider
• spec: Load/refresh OpenAPI spec for a provider
• ops: List available operations for a provider
• call: Call an API operation by operation ID
• raw: Make a raw HTTP request to any endpoint

Parameters

Parameter	Type	Description
action	str	Action to perform (default: "list")
provider	str	Provider name (e.g., "cloudflare")
api_key	str	API key for config action
api_secret	str	API secret (if needed)
account_id	str	Account/org ID
base_url	str	Override base URL
spec_url	str	URL to OpenAPI spec
operation	str	Operation ID for call action
params	str	JSON parameters
body	str	JSON request body
method	str	HTTP method for raw action
path	str	URL path for raw action
search	str	Search filter for ops action
tag	str	Tag filter for ops action

Credential Storage

Credentials are stored in ~/.hanzo/api/credentials.json with basic obfuscation. For production use, consider using system keyring or a secrets manager.

OpenAPI specs are cached in ~/.hanzo/api/specs/.

Adding Custom Providers

You can add any provider by providing a base URL and API key:

from hanzo_tools.api import get_credential_manager

cred_manager = get_credential_manager()
cred_manager.set_credential(
    provider="custom-api",
    api_key="your-key",
    base_url="https://api.custom.com/v1"
)

Then load a spec:

from hanzo_tools.api import get_client

client = await get_client(
    "custom-api",
    spec_url="https://api.custom.com/openapi.json"
)

Security Notes

• API keys are stored with basic base64 obfuscation (not encryption)
• Credentials file has restrictive permissions (0600)
• Environment variables are preferred for sensitive credentials
• Never commit credentials to version control
