Smarty Rate Limits
Smarty implements two categories of rate limits: security-based limits that apply per IP address on embedded-key requests, and plan-based limits that throttle the entire license when lookups per second exceed the plan allowance. Both return HTTP 429 with a Retry-After header. Rate limits use a Leaky Bucket algorithm.
Smarty Rate Limits is the machine-readable rate-limit profile for Smarty on the APIs.io network, conforming to the API Commons Rate Limits specification.
It captures 3 rate-limit definitions, measuring requests and address_lookups_per_second.
Tagged areas include Address Verification, Geocoding, Address Autocomplete, ZIP Code, and Address Intelligence.
