Diffbot
DATA · DATA & ANALYTICS
Structured page extraction and Knowledge Graph search on their own key.
Connecting Diffbot in practice
Diffbot charges credits at wildly different rates for the same call volume: an Extract page costs 1 credit, a Knowledge Graph entity download costs 25, and a single facet query costs 100 — the price of a hundred page extractions. The free tier is metered per minute (5 calls) while paid tiers are per second (5 and 25), so the unit changes when you upgrade.
Rate limits
- All APIs: Free 5 calls per minute, Startup 5 calls per second, Plus 25 calls per second.
- Extract API: Free tier capped at 10,000 calls per month.
- Natural Language API: Free tier capped at 500 calls per month.
- DQL and Enhance: Free tier capped at 400 entities per month.
- Crawl and Bulk Extract on Plus: 25 active jobs and 1,000 total jobs.
Worth knowing
- Credit costs per call: Extract 1 (2 with a data-center proxy), Natural Language 1 per document of 1 to 10,000 characters, Knowledge Graph entity download 25, facet query 100, Enhance 25, Enhance with refresh 100.
- Credits reset monthly on non-enterprise plans and do not carry over, and overage is billed automatically at the plan’s per-credit rate rather than blocked, so a runaway agent spends rather than stops.
- Crawl spidering for links costs 0 credits but every successfully crawled page that is extracted costs 1, so the bill tracks pages found rather than the number of API calls made.
- The token is a query-string parameter on every request, so it appears in server logs, referrers and any URL captured for debugging.

What an agent can do
Each action is granted on its own. An agent allowed to read is not thereby allowed to write, and the scope beside each row is what the acting user must have connected for it to run at all.
