One API Key For Every Tool
24 search, scraping, browser-automation and voice APIs behind one key
Provider-native endpoints at provider-native prices — one credit balance, $5 free to start
For you and your AI agents
One API for Any Tool
Access every integrated tool through a single, unified endpoint — each tool's native API, parameters and responses, passed straight through.
Browse tools →Unified Billing
One balance across every tool. No per-service accounts, no scattered invoices, no credentials to juggle.
How billing works →Instant Access
Use any integrated tool the moment you get your key — no per-provider signups, approval waits or onboarding.
Quickstart →Drop-in Passthrough
Keep your existing code. We forward to each provider's native endpoints and return responses unmodified.
API reference →Featured Tools
One key, one bill — across every integration.

The full ElevenLabs REST API for text-to-speech and voice, exposed via wildcard routing.
Start in three steps
From signup to your first request in minutes.
Get your API Key
Generate a key from your dashboard — one key works across every tool and provider.
Replace the base URL
Point your existing tool's SDK or requests at api.auxiliar.ai — or just ask your agent to do it for you.
curl https://api.auxiliar.ai/serper/search \ -H "Authorization: Bearer $AUXILIAR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"q": "claude ai"}'
Built for unattended agents
The operational contract, stated plainly — every claim links to where you can verify it.
Keys stay server-side
Upstream provider keys are injected per request and never enter your agent's context or code. The one auxiliar key is the only secret it holds.
How passthrough works →Deterministic failure
An empty balance returns HTTP 402 — no silent degradation. Auto-top-up keeps long runs funded, and every request lands in your ledger with its exact cost.
How billing behaves →Measured, not promised
Every provider is benchmarked on the same public corpora — quality, latency, cost per success, error rate — and published with run dates, weak scores included.
See the evals →Readable by machines
Live uptime at status.auxiliar.ai. Agents can read /llms.txt, /llms-full.txt and /evals.json, or append .md to any docs page for clean Markdown.
