​
Rate Limit

The default rate limit is 60 requests per minute, with a batch size of up to 100 contacts per request. This means you can send up to 6,000 contacts per minute to FullEnrich.

Need a higher rate limit?
Contact our team—we can increase your rate limit if needed.

See the Rate Limits section for details.

​
Queue Size

Each workspace has a default queue size of 100 concurrent enrichments.
This means up to 100 contacts are processed at the same time within your workspace.
If you submit more than 100 contacts, the extra contacts wait in the queue until a slot is free. As soon as a running enrichment finishes, the next one in the queue starts.

Need a higher queue size?
Queue size can be increased for high-volume customers and is set based on your volume in the commercial agreement. Reach out to our team to discuss.

​
Batch vs. Single Enrichment

FullEnrich uses the /enrich/bulk endpoint for all enrichment. You can use this endpoint for both single and multiple contacts.
If you want to enrich one contact in real-time, simply send a batch with a single contact.
For processing lists or automated jobs, you can submit larger batches (up to the batch limit).

​
Speed & How to Display Progress to Customers

Most enrichments complete within 30 to 90 seconds per contact.

What matters most for users is the value they get from the enrichment. If your product communicates that you’re sourcing data from many premium providers to guarantee the most complete and up-to-date information, users naturally accept the wait. The more transparent you are about the process, the more the waiting time feels justified.

Best practices for integrating enrichment in your product:

  • Do not block users during enrichment. Let them continue their workflow while the enrichment runs in the background.
  • Display a clear status in the UI so users know the process is ongoing.
  • Rotate between a few dynamic loading messages to make the experience smoother.

Examples of UI messages:

  • Enrichment in progress…
  • Searching accross 20 data providers…
  • Checking every corner…
  • Digging deeper…

The wait feels proportional to the value delivered. Good communication here turns the wait into a signal of thoroughness.
