OpenClaw is one of the fastest-growing open-source autonomous agents — a local-first assistant you message on your own devices, extended through its AgentSkill system. Out of the box it can run commands and make HTTP calls; what it can’t do is reach the live web with quality search and scraping unless you wire in a provider. This guide adds that with a single Auxiliar key, so one skill unlocks every web-access provider instead of one.
Why one key matters for an autonomous agent
An autonomous agent can’t pause to fill out 24 signup forms, pass KYC, and paste 24 API keys. It needs one credential that reaches everything. That’s exactly what Auxiliar is: a gateway where one bearer token calls every search, scraping, crawling and voice provider at https://api.auxiliar.ai/<provider>/..., with the upstream keys injected server-side and usage billed to one balance. Give OpenClaw that one key and it can search the web, read pages, and get past anti-bot — without you managing a single provider account.
Step 1 — set the key
Put your Auxiliar key where the agent’s shell can read it:
export AUXILIAR_API_KEY="aux_..." # from accounts.auxiliar.ai
Step 2 — a web-access skill
OpenClaw skills are small, self-contained capabilities the agent can invoke. The durable core of the skill is the gateway call — a search and a page-read the agent can run as shell commands:
# Search the live web
curl -s https://api.auxiliar.ai/serper/search \
-H "Authorization: Bearer $AUXILIAR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"q": "QUERY"}'
# Read a page as clean markdown
curl -s https://api.auxiliar.ai/firecrawl/v1/scrape \
-H "Authorization: Bearer $AUXILIAR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"url": "URL", "formats": ["markdown"]}'
Wrap those two calls in an AgentSkill (per OpenClaw’s current skill format — check its docs, as the schema evolves) with instructions like “Use web_search for anything recent or factual; use read_page to open a result.” That’s the whole integration: the agent now searches with Serper and reads with Firecrawl, the two category leaders in our benchmarks, on your one key.
Step 3 — make it resilient
Because every provider is on the same key, your skill can fall back when a site blocks the first scraper — swap /firecrawl/v1/scrape for /scrapfly/scrape or /brightdata/unlocker and retry. See scrape without getting blocked. For an unattended agent, that cross-provider fallback is the difference between “task failed” and “task done.”
What you get
One key, and OpenClaw can reach all 24 providers in the catalog — search, scrape, crawl, extract, screenshot and voice. No per-provider signups, no keys to rotate, one bill. Point it at the gateway and your agent has the whole web.
