Getting Started

Authentication and basic API usage

Base URL

https://firmafind.at

Authentication

All API requests require an API key in the x-api-key Header:

x-api-key: YOUR_API_KEY

Example Request

curl -X GET "https://firmafind.at/api/search?name=example" \
  -H "x-api-key: YOUR_API_KEY"

Rate Limiting

Understanding API rate limiting and quota windows

To ensure platform stability, the FirmaFind API employs two layers of rate limits: a Daily Quota (resetting at midnight ) and a Burst Limit (sliding 60-second window to prevent sudden spikes in traffic).

Rate Limit Tiers

Tier / User Status	Daily Quota	Burst Limit	Authentication
Anonymous	30 requests / day	5 requests / min	No Key (IP-based)
Free User	50 requests / day	120 requests / min	API Key Required
Trial User	500 requests / day	30 requests / min	API Key Required
Subscriber	Unlimited	120 requests / min	API Key Required

When Exceeded

If you exceed either the daily quota or the 60-second burst window, the API returns a HTTP 429 Too Many Requests response code. The response contains standard rate-limiting headers:

Header	Type	Description
X-RateLimit-Limit	integer	Your tier's maximum daily request allowance
X-RateLimit-Remaining	integer	Remaining requests available within the current daily window
X-RateLimit-Reset	timestamp	Unix epoch timestamp (seconds) when the daily quota resets
Retry-After	integer	Returned only on `429` responses. The number of seconds you must wait before retrying.
X-Usage-Policy	url	Link to the Acceptable Use Policy

Best Practices & Tips

Check headers to monitor usage and proactively pace requests.
Handle 429 status codes programmatically and implement exponential backoff.
Cache search results locally (data is updated daily) to conserve credits and improve response times.
Sandbox endpoints (/api/sandbox/*) are free (0 credit cost) but have a fixed limit of 5 requests/minute per user.

Rate Limiting

IP-based Limit

30 Requests/Tag

Per IP address, reset daily. No API key required.

GET/api/sandbox/searchSandbox / API Key Required (0 Credits)

Developer Sandbox Search

Fictional company search endpoint designed for testing structures and prototyping without wasting API credits or LLM tokens. Requires authentication (free sign-up), but is completely free to call. Returns a static array of exactly three fictional companies with an artificial 2.5s latency simulation.

Perfect for AI Agent Prototyping

Testing JSON schemas with LLMs often wastes trial API credits. Use this endpoint to receive the exact schema output of our production API without consuming any credits. An API key is required (sign up is free). Slowed by design (2500ms response time) to avoid production abuse.

Authentication

Requires your API key in the x-api-key header. Sandbox requests do not consume your account credits (0 credit cost).

x-api-key: YOUR_API_KEY

Query Parameters

All query parameters are accepted but do not affect the returned result. The API always returns the same three mock companies.

Parameter	Type	Required	Description
q / query	string	Nein	Search term (e.g. `My Company`)
zip	string	Nein	Postal Code
uid	string	Nein	UID number

Example Request

curl -X GET "https://firmafind.at/api/sandbox/search?q=test" 
  -H "x-api-key: YOUR_API_KEY"

Response Fields

The response structure matches the main company search schema:

Field	Type	Description
fnr	string	Firmenbuchnummer (Company Register Number)
name	string	Official company name
sitz	string	Company seat (city)
rechtsform	string	Legal Form (e.g. Gesellschaft mit beschränkter Haftung)
status	string	Status (e.g. aktiv)
gericht	string	Responsible local court
country	string	Country code (AT/CZ)
_meta	object	Sandbox notice metadata for testing integrations
