Verdicts

Spider

Keyless /scrape and working x402 v2 on every core route, so an agent needs no account. Operated by BAGELMEN LLC with no address, retention periods or DPA in the privacy policy.

Zyte API

One POST endpoint with an OpenAPI 3 contract picks proxies, browser rendering and extraction per site, bills only successful responses, and sends problem+json errors with Retry-After. Prices vary by target site across five tiers, so cost per request isn't known before the site is assigned one, and no dated API changelog was found.

Before you call either

Spider

  1. Every content route returns a JSON array, even /scrape. The status field is the page's, not the API call's
  2. Leave request on smart and set return_format to markdown for LLM input
  3. Set limit on /crawl. Unset, it caps only at your credit balance
  4. Use /scrape with stealth: true instead of /unblocker, which is deprecated
  5. Honour Retry-After on 429. Keyless use allows 4 requests a minute

Zyte API

  1. Send the API key as the Basic auth username with an empty password to https://api.zyte.com/v1/extract. Set only one of httpResponseBody or browserHtml, or one extraction field
  2. Ask for httpResponseBody before browserHtml. Browser requests cost about eight to thirteen times more per tier
  3. Retry 429, 503 and 520 after the Retry-After seconds, with backoff. They aren't billed. Don't retry 400, 401, 422 or 451
  4. Read statusCode in a 200 response. A target site's 404 comes back as a successful, billed Zyte API response
  5. Have the owner set a blocking spending limit on the key you use. A 403 /auth/account-suspended means the limit or the trial month ended

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
