Quickstart
CrawlVolt is the browser API for AI agents: a web access layer that opens modern pages, returns agent-ready content, and can perform controlled browser actions.
You do not need to operate Chromium, wait for JavaScript applications, or normalize page output in every agent.
1. Create a key
Create an account, open Account, and create an API key. New keys include the scrape, browse, sessions, crawl and usage scopes. The full secret is displayed once.
2. Fetch and extract a page
curl --request POST https://www.crawlvolt.com/v1/scrape \
--header "Authorization: Bearer $CRAWLVOLT_API_KEY" \
--header "Content-Type: application/json" \
--data '{
"url": "https://example.com",
"formats": ["markdown", "text", "metadata"]
}'The response keeps page outputs under outputs and operational data at the top level:
{
"request_id": "req_01JWD8",
"status": "completed",
"final_url": "https://example.com/",
"engine_used": "chromium",
"outputs": {
"markdown": "# Example Domain\n...",
"text": "Example Domain ...",
"metadata": { "title": "Example Domain" }
},
"billing": { "billable": true, "units": 1, "unit": "page" }
}3. Interact before extraction
POST /v1/browse executes actions in order and then returns the same output model:
curl --request POST https://www.crawlvolt.com/v1/browse \
--header "Authorization: Bearer $CRAWLVOLT_API_KEY" \
--header "Content-Type: application/json" \
--data '{
"url": "https://example.com/search",
"actions": [
{ "action": "fill", "selector": "input[name=q]", "value": "browser API" },
{ "action": "click", "selector": "button[type=submit]" },
{ "action": "wait", "selector": "main" }
],
"formats": ["markdown", "screenshot"]
}'Use the returned request_id when reporting an operational failure.
