The limit
Each live key may make 600 requests per minute; each test key 60. The budget is counted per key, not per IP address, so two integrations with their own keys never eat into each other’s — and integrations behind one NAT do not either. A request over the limit is answered with 429 Too Many Requests and changes nothing.
Headers
Every response carries the current state of the key’s budget:
| Header | Meaning |
|---|---|
x-ratelimit-limit | Requests allowed per minute for this key (600 or 60). |
x-ratelimit-remaining | Requests left in the current window. |
x-ratelimit-reset | Seconds until the window resets. |
retry-after | On 429 only: seconds to wait before retrying. |

Wait retry-after seconds, then send the same request again. A request refused with 429 was not applied, so retrying it is safe — and with an Idempotency-Key, so is every other retry.

- Use the bulk endpoints:
POST /items/batch,POST /passports/publish,POST /passports/bulk-lifecycleandPOST /passports/import-updateseach take up to 1,000 rows. - Page lists with
limit=200instead of fetching records one by one. - Sync with
updated_sinceand webhooks instead of polling everything. - For a full copy,
GET /export/archiveis one request. - Watch
x-ratelimit-remainingin long jobs and slow down before it reaches zero.
