Attom Data Rate Limits

ATTOM reserves the option to limit calls per minute, hour, day, and month to keep response times acceptable across customers. The single numeric limit ATTOM documents publicly is 200 API calls per minute. Beyond that, each subscription plan carries a fixed number of allowed calls per month; the monthly allowance resets on the subscription's usage cycle. Response payloads are capped at 100 records per page (default page sizes are smaller), and radius searches default to 5 miles with a 20-mile maximum. Enterprise customers can negotiate custom per-minute and monthly limits with ATTOM in advance.

Attom Data Rate Limits is the machine-readable rate-limit profile for ATTOM on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 5 rate-limit definitions, measuring requests, records, and miles.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Policies

Fair Use Throttling
ATTOM throttles calls that exceed the per-minute ceiling to maintain acceptable response times for all customers.
Monthly Usage Reset
The monthly call allowance resets on the subscription's usage cycle; overage handling is defined by the plan.
Backoff Strategy
Clients should implement exponential backoff with jitter and honor Retry-After on 429 responses.
