Verdicts

Bright Data

Pay only for successful requests, $1.50 per 1,000 on Web Unlocker and SERP. No public status page or incident history.

Diffbot

Extract returns typed JSON for articles, products, discussions and other page types with no selectors to write, under a public OpenAPI 3.1 contract and a free plan that needs no card. The API token travels in the URL query string, tokens carry no scopes, and no security page, certification or security.txt was found.

Before you call either

Bright Data

  1. Connect with OAuth or keep the ?token= URL out of logs and shared configs
  2. Add groups= or tools= to the MCP URL only for the extractors you need. The full set is 69 tools
  3. Retry reject_block errors, since each attempt uses a different peer. Certificate and DNS errors fail the same way twice
  4. Back off on a 429 sr_rate_limit. Bright Data throttles a target whose success rate drops
  5. Use the batch tools for up to 10 searches or scrapes in one call

Diffbot

  1. Call GET https://api.diffbot.com/v3/analyze?url=<encoded URL>&token=<token> when the page type is unknown. Use /v3/article or /v3/product to force one schema
  2. Keep the token out of logs and shared URLs. It sits in the query string, so any proxy or log that records the request URL records the token
  3. Stay under 5 calls a minute on Free, 5 a second on Startup and 25 a second on Plus. On 429 wait at least one second and back off
  4. Check a 200 response for errorCode. The official client raises ExtractionError when a 200 reports a failed extraction
  5. Set useProxy=default only when a site blocks the fetch. A proxied page costs 2 credits against 1
  6. Install diffbot from PyPI, not diffbot-python, which stopped at 0.3.0
