Scrapingdog vs Zyte API

Scrapingdog

A plain request is 1 credit, about $0.20 per 1,000 on Lite. API key only travels in the URL query string.

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.

Scrapingdog

1. Add dynamic=false unless the page needs JavaScript. It cuts the cost from 5 credits to 1, whatever the MCP description says
2. Keep request URLs out of logs, since they carry api_key
3. Set client timeouts above 60 seconds and retry on 429 or timeout. Failures aren't billed
4. Prefer the parsed endpoints (Google, Amazon) over scraping the raw page when one exists

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
