🚦Rate Limits & Data Size

IBISWorld applies rate limits to ensure service quality, system stability, and fair usage across all clients.

Cached Results

Cached responses are permitted. However, we recommend frequent refreshes since reports are updated regularly (between 1 - 4 times per year).

Use the /industry/v3/updatedreports endpoint to check which reports have changed within a specific time period.

IBISWorld’s API offers three levels of access:

Full Report Access – The /industry/v3/fullreport endpoint returns the entire contents of a report.

PDF Downloads – The /downloads/v3/report endpoint provides full reports in PDF format.

Granular Access – Retrieve only the sections you need using the /industry/v3/sections endpoint.

Endpoint / Data Type	Typical Response Time	Typical Size	Notes
Full Report (`/industry/v3/fullreport`)	2–4 seconds	30–135 KB	Entire contents of one report in JSON output
PDF Download (`/downloads/v3/report`)	~2 seconds	170–300 KB	Pre-formatted PDF, larger than JSON
Individual Sections	~1 second	~1 KB per section	Fastest option, minimal payload
Multiple Sections (`/industry/v3/sections`)	~1-2 seconds	~1 KB per section	Fastest optoin when you only need specific sections to minimize size and improve performance.
Lists	~1–2 seconds	5–40 KB	Lists of industries or other products by country/region

Use granular endpoints when you only need specific sections to minimize size and improve performance.

Cache report data where appropriate, and refresh selectively using /industry/v3/updatedreports.

For bulk workloads (e.g., multiple PDFs), schedule during off-peak hours and respect API rate limits.
