Why treg.to

Why call Crawl4AI through treg.to

No Crawl4AI signup

Eligible tools run on treg.to's key, metered per call from a prepaid balance.

Price before the call

The provider's own rate, $0.000 markup. How billing works.

No subscription, no seats

Platform calls are charged per call. $1.00 free per new team, no card to start.

Your own Crawl4AI key is free

Register it and those calls are never metered. Your key always wins.

Switch by changing a word

Another provider is a different word in the prompt, not a new integration.

One key, the whole catalog

The same token calls AnyAPI, Apify, Context.dev and 3,390 other tools.

All 11 Crawl4AI tools

Open web & SEO data · 10 tools
  • Answer a question from the web (experimental) · Platform + BYOK · live-verified · $0.004/success
    A direct answer generated from the web's current top results, with the sources it drew on; answered is false when there is none yet. Experimental: the shape may change. crawl4ai.web.answer
    1 credit base times the effort; a deep answer cost 2 live. The 4-credit hold is the hardest effort; the x-c4-cost header settles the actual charge.
  • Scrape or crawl a list of URLs in one batch, streamed · Platform + BYOK · live-verified · $0.05/success
    Scrape up to 25 URLs in one call; results stream back as NDJSON, one line per URL as it finishes, then one summary line with the batch's total cost. crawl4ai.web.extract.batch
    Each URL costs like a scrape (0.25 to 2 credits) and its line carries that cost; the closing summary line carries the total, which settles the call. The 50-credit hold is 25 URLs at the hardest effort. A live two-URL batch cost 0.25 per archived URL.
  • Price a scrape before running it · Platform + BYOK · helper · live-verified · free
    The credit range a scrape of one URL (or a list) would cost, from Crawl4AI's own effort model. Free. crawl4ai.web.extract.estimate
    Estimates spend no credits.
  • Extract structured JSON data from a web page with an LLM · Platform + BYOK · live-verified · $0.01/success
    Scrape a page (crawled for you) or read your own content, and return typed JSON matching a JSON schema and/or a plain-English instruction, extracted by an LLM. crawl4ai.web.extract.structured
    0.5 credit base times the page's effort, plus the model's tokens (1 credit per 5,000-token block). A three-record extract from the HN front page cost 1.952 live. The 10-credit hold is an upper bound for a large page; the x-c4-cost header settles the actual charge.
  • Scrape or crawl a web page to clean Markdown for LLMs · Platform + BYOK · live-verified · $0.002/success
    Scrape one URL into clean, LLM-ready Markdown and/or HTML. Crawl4AI picks the cheapest engine that works (archive, plain fetch, real browser that renders JavaScript), with optional links, media, metadata and tables; proxies for sites that block datacenters. crawl4ai.web.scrape
    0.5 credit base times the page's effort (x0.5 archived, x1, x2 browser, x4 hard). The 2-credit hold is the hardest page; the x-c4-cost header settles the actual charge (an archived example.com cost 0.25 live).
  • Read a scrape job's results · Platform + BYOK · helper · live-verified · free
    An owned job's results as NDJSON, one line per URL, 500 per page. crawl4ai.web.scrape.job.results
    Reading results spends no credits.
  • Crawl many URLs as a background scrape job · Platform + BYOK · live-verified · $1/success
    Submit up to 500 URLs as a background job; poll its status, then read the results. Nothing waits on a slow page. crawl4ai.web.scrape.job.start
    Each URL costs like a scrape; the finished job's usage.cost (credits, after refunds for failed URLs) settles the call. The 1,000-credit hold is 500 URLs at the hardest effort.
  • Check a scrape job · Platform + BYOK · helper · live-verified · free
    An owned job's status, per-status counts and credit usage. crawl4ai.web.scrape.job.status
    Polling spends no credits.
  • Search the web, fast multi-engine web search · Platform + BYOK · live-verified · $0.001/success
    Browser-free, multi-engine web search with ranked, cleaned results (title, url, snippet, source). crawl4ai.web.search
    1 credit base times the effort; a cached search cost 0.5 live. The x-c4-cost header settles the actual charge.
  • Search the web with rich results · Platform + BYOK · live-verified · $0.002/success
    Web search plus a rich block: follow-up questions, related queries, an entity card, videos, news and discussions. crawl4ai.web.search.rich
    A rich search cost 2 credits live. The x-c4-cost header settles the actual charge.
The provider account itself — usage, quota, balance (not a content platform) · 1 tools
  • Check credit balance · BYOK only · account management · live-verified · No treg charge; upstream free
    Returns the account's credit balance, this month's spend and whether auto recharge is on. Trails the per-call x-c4-balance header by about a minute. crawl4ai.account.usage
    Reading the balance spends no credits.

Reliability badges come from live traffic through treg.to. Live-verified means a successful provider check; it does not verify every request variant.

Questions

Before you start

Do I need a Crawl4AI account?

For 10 platform tools, no. The other 1 require your own Crawl4AI key. All 11 accept your own key, and treg never meters BYOK calls.

What does a call cost?

Each tool on this page shows its rate; the cheapest is $0.001/success. The rate is the provider's own and treg.to adds no markup; it is billed per call from a prepaid balance. It is not Crawl4AI's subscription pricing, which is on their own site. New teams start with $1.00 of free credit.

How do I add Crawl4AI to Claude Code?

Run: claude mcp add --transport http treg https://treg.to/mcp. One MCP server carries Crawl4AI and the rest of the catalog.

Which frameworks does it work with?

Anything that speaks MCP (Claude Code, Claude Desktop, ChatGPT, Codex, Cursor, Grok) and anything that can make an HTTP request (LangChain, CrewAI, LlamaIndex, plain code).

Is this the official Crawl4AI MCP server?

No. treg.to serves Crawl4AI's real API through its own metered proxy: the request is the provider's own, the credential is injected server-side, and the answer is relayed verbatim. The official Crawl4AI channels are linked above.
