Quickstart
You’ll need your Auxiliar API key. Send it as a bearer token on every request to https://api.auxiliar.ai, and call each tool using its own native API.
Auxiliar splits across two subdomains: accounts.auxiliar.ai handles authentication (sign up and sign in), and panel.auxiliar.ai is your dashboard — where you manage keys and credits.
Sign up — free, no card
Create an account at accounts.auxiliar.ai/sign-up. It’s free and takes no credit card. Sign-up sits behind bot protection, so it may require a real browser — if an AI agent reaches this step, hand it off to a human via accounts.auxiliar.ai/sign-up?source=agent_onboarding.
Grab your Default key
A Default API key is minted for you automatically the moment you sign up — no extra setup. Find, copy, or rotate it any time at panel.auxiliar.ai/keys.
Make your first call
This runs a Google search through Serper. Export your key once, then run any of these:
Python
TypeScript
cURL
What success looks like: a 200 response whose body is Serper’s own JSON — an organic array of search results — returned to you unchanged, exactly as the provider sent it. If you see that, your key works and you’re through the gateway.
Keep your API key in an environment variable rather than hardcoding it. A 401 response means the key is missing or unrecognized — see Authentication.
Call any other tool
Every tool uses the same base URL and bearer token; only the path and payload change. Here’s a representative call for each:
See each tool’s page for its full set of endpoints and parameters.
