Gotchas & Limits

DuckDuckGo can throttle datacenter IPs

The DuckDuckGo HTML lite driver has no API key, but shared CI or server IPs may receive anti-bot responses. Treat it as a fallback, not a high-volume primary.

Image support differs by driver

Web-only drivers are skipped for searchImages(). This is expected and appears in the execution attempts.

Rate limit metadata is not enforcement

rate_limit_per_minute helps document provider capacity but does not throttle calls by itself.

Limits to model in host apps

  • Provider quota and billing.
  • Regional API behavior.
  • Search result freshness.
  • Duplicate image URLs across providers.
  • Page URLs that redirect or block image scraping.
