How the API works
Quick Start
Send your API key in the Authorization header. Base URL https://api.findutils.com/api
# Encode text to Base64
curl -X POST https://api.findutils.com/api/tools/base64/execute \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"text": "Hello, World!", "action": "encode"}'Response Format
All endpoints return JSON with a consistent structure.
{
"success": true,
"result": {
"result": "SGVsbG8sIFdvcmxkIQ=="
},
"meta": {
"tool": "base64",
"executionMs": 0
}
}Authentication
Running a tool needs an API key: send Authorization: Bearer YOUR_API_KEY, or X-API-Key: YOUR_API_KEY. Without a key, a tool call answers HTTP 402 Payment Required. The catalog and the schemas stay open. Keys are not for sale yet: ask for early access. How to get a key. Rate limits are per IP address. For higher limits, contact us.
API endpoints
| GET | /api/health | Health check |
| GET | /api/tools | List all tools with schemas |
| GET | /api/tools/:id | One tool with its schema |
| POST | /api/tools/:id/execute | Run a tool (API key) |
| GET | /api/openapi.json | OpenAPI 3.1 specification |
Error handling
A failed request returns a structured error: VALIDATION_ERROR (400), PAYMENT_REQUIRED (402, no API key), NOT_FOUND (404), RATE_LIMITED (429, 60 requests a minute per address without a key) or INTERNAL_ERROR (500).
{
"success": false,
"error": {
"code": "VALIDATION_ERROR",
"message": "Missing required field: text"
}
}API keys
Running a tool needs an API key. Keys are not for sale yet: ask for early access. Running a tool means POST /api/tools/:id/execute (also under /v1) and the MCP method tools/call.
Send the key in the Authorization: Bearer YOUR_API_KEY header. The X-API-Key: YOUR_API_KEY header also works.
Without a key, a tool call answers HTTP 402 Payment Required with the error code PAYMENT_REQUIRED. The error links back to this section.
These stay open with no key:
GET /api/tools, GET /api/tools/:id, GET /api/openapi.json, MCP initialize, MCP tools/list.
The browser tools on findutils.com stay free and unchanged. With a key, the rate limits follow the key and its plan, not your address.
