Reference Guide - Access
From SRP API Docs
StructuredRetailProducts.com provides two types of API access: SRPFeed – providing a limited number of API calls/month SRPUltraFeed – providing an unlimited* number of API calls/month
- unlimited (with fair usage).
All requests will be monitored and every successful call/request will be counted. If the user exceeds the total number of allowed calls/requests per period, the status code 405 will be sent.
Additionally access element will be included in the response detailing frequency and allowance which will show user allowances:
<status code="405">User has no more access according to his allowed frequency</status> <access> <frequency>daily</frequency> <allowance>100</allowance> </access>
