Rate Limits

VeriflowAPI enforces rate limits to ensure fair access and system stability for all customers.

Monthly verification quotas

Each plan includes a monthly verification quota. This is the total number of /v1/verify calls you can make per billing month.

Per-minute rate limits

In addition to monthly quotas, per-minute rate limits prevent burst traffic from affecting system stability.

Rate limit headers

Every API response includes headers showing your current usage:

Handling rate limit errors

When you exceed your per-minute limit, you will receive a 429 response:
The retry_after field tells you how many seconds to wait before retrying.

Implementing retry logic — Python

Bulk verification

If you need to verify large batches of providers, use the bulk endpoint rather than making individual requests in a loop. This is more efficient and counts against your quota the same way.
Accepts an array of up to 100 providers per request. Available on Production, Scale, and Enterprise plans.
