Inventory API Request Limits

Rate limits are an essential component of the TrustedParts.com Inventory API service. Each request to the TrustedParts.com Inventory API incurs a cost in compute resources, network bandwidth, logging, and monitoring. To allow us to continue to provide this service free of charge, we encourage all users to be responsible and only make as many requests as they actually need.

We strongly discourage TrustedParts.com Inventory API accounts from planning to consume all of their rate limits. Our rate limits are meant to support exceptional cases where an account temporarily has an unusual amount of activity and needs to make more requests than usual. For normal usage, please plan to only make as many requests as are actually necessary. If you think it's necessary to have a request volume that consistently consumes your rate limit volume, please let us know so we can discuss more about your use case.

Soft Limits

The following chart indicates the soft limits for TrustedParts.com Inventory API requests. Requests from API customers who exceed these limits are still processed, but they use a search process that consumes fewer system resources. This optimized search process renders pricing and availability information from cached data instead of real-time data. Note: The soft limits only apply to requests where the IsCrawler and UseCachedData parameters are false. If either of those parameters are true, the soft limits do not apply.

Hard Limits

The TrustedParts.com Inventory API will not process requests that contain more than 50 part numbers. If you need to search for more than 50 part numbers, please make multiple requests to the TrustedParts.com Inventory API with each request having no more than 50 part numbers. The following chart indicates other hard limits for TrustedParts.com Inventory API requests. If an API customer exceeds one of these limits, their API key will be suspended for an hour. Repeated suspensions could lead to an API key being revoked.

The Trusted Source for Authorized Inventory

TrustedParts.com was created by ECIA in collaboration with participating distributors as a free service to support the authorized electronic components industry by giving users access to aggregated price and availability data for genuine parts from only authorized sources.

While other inventory aggregation sites may include data from sources that are not authorized by the manufacturer, ECIA works extensively on an ongoing basis to verify that price and availability data displayed on TrustedParts.com is only for products for which the distributors are authorized/franchised. This is why TrustedParts.com is the best source for searching the authorized channel for the electronic components you need.
Membership in ECIA is not required to participate on the site.
