There’s a difference between building an agent and running one that operates on its own. The moment an agent acts unattended — picking tools mid-task, working through a queue, spending its own budget — the way it acquires capabilities has to change. It can’t stop to read a pricing page, create an account, verify an email, and copy an API key. It needs capabilities it can reach with one credential it already holds. For web access, that’s Auxiliar.
The problem with the old model
The web-access market is 24+ separate providers — a search API here, a scraper there, a crawler, a voice API. The human model is: evaluate each, sign up, enter a card, manage a key, reconcile invoices. An autonomous agent can do none of that. Twenty-four signups, twenty-four KYC flows, twenty-four keys to rotate — it’s a wall an agent hits and stops.
The one-key model
Auxiliar collapses all of it into a single gateway. One bearer token reaches every provider at https://api.auxiliar.ai/<provider>/...; the upstream keys are injected server-side (the agent never sees or handles them); usage is metered to one balance. From the agent’s side, the entire web is one credential:
curl https://api.auxiliar.ai/serper/search \
-H "Authorization: Bearer $AUXILIAR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"q": "anything"}'
Change serper/search to firecrawl/v1/scrape, tavily/search, exa/search, or any of the 24 providers — same key, same bill.
Why this shape wins for agents
- No signup wall. One credential unlocks the whole catalog. This is more valuable to an agent than to a human, because an agent literally cannot complete two dozen human onboarding flows.
- Keys stay server-side. The agent never holds upstream secrets — a cleaner, safer trust boundary for autonomous operation.
- Best-of-breed per task. No provider wins every job; our benchmarks show different leaders for search, scraping, crawling and extraction. On one key, the agent routes each request to whichever wins.
- Fallback on failure. A blocked scraper is routine, not exceptional. The agent reroutes to the next-best provider without a new account. See scrape without getting blocked.
- Metered, not subscribed. Usage bills to one balance — the right primitive as agents move toward paying for what they consume.
Get started
Point your agent at the gateway with a concrete setup for OpenClaw, Hermes, or any MCP client — or just give it the key and the base URL. Grab one at accounts.auxiliar.ai and the agent has the whole web.
