{query, num_results = 5, include_domains?, exclude_domains?}
Read any public page as Markdown, or only the passages that answer a question.
{url, query?}
Pages like a given URL, outside its domain: alternatives, related docs.
{url, num_results = 5}
Up to 3 searches in parallel, deduped into one Markdown evidence pack.
{query, sub_queries?, num_results_per_query = 5}

"threshold": 1000,
"pack": "builder",
"monthly_max_usd": 500
}✓ monthly cap ≤ $500 through MCP
Your agent can check its balance and turn on auto-reload: below 1,000 credits, buy Builder again, capped per month.

$1.00/ 1k tool calls
1 credit per search, page or find-similar call. Balance and auto-reload are free. One-time payment. Credits never expire. Full Markdown and pruning included.
No. Without CONTEXTFETCH_API_KEY the server runs keyless: 25 requests per IP per UTC day. Set the variable to a paid key for more. When credits or the free tier run out, tools return the payment link as an error result instead of crashing, so your agent can show it to you.
Any client that runs stdio MCP servers: Claude Code, Claude Desktop, Cursor, Windsurf and others. It is an npm package started with npx, so Node.js is the only requirement.
Search, extract_url and find_similar cost 1 credit per call. deep_research costs 1 credit per sub-query, at most 3. balance and auto_reload are free.
Only through auto-reload on a key whose card was saved at checkout. Through the API or MCP a key can turn auto-reload off, lower its values or change the pack, but the monthly cap can never go above $500; a higher cap needs the browser. A declined payment turns auto-reload off and the balance tool reports the error.
To https://api.contextfetch.dev, or the URL in CONTEXTFETCH_API_BASE. The key travels only in the Authorization header, and we store only its SHA-256 hash.
One line, no key, no signup.
