*Required

NameValueAdditional Information
CompanyID*Enter the assigned company identifierThe assigned company identifier can be found on the API Credentials page.
APIKey*Enter the assigned API keyThe assigned API key can be found on the API Credentials page.
Queries*Add a separate Queries section for each part number search. Note: If you enter multiple part numbers, an exact match search will be performed for each part number. Partial match results are only available for single part number requests.
SearchToken*Enter the part numberThe part number must be at least 3 characters long.
ManufacturersAdd this section to limit the search results to one or more manufacturers. Omit this section to search all authorized manufacturers.
     - NameEnter the name of the manufacturerAdd separate Name elements for each manufacturer to search. See our List of Manufacturer Names for supported manufacturers.
CountryCodeEnter a two-character ISO code or leave blank for geolocationLeave this field blank if you would like us to geolocate the SourceIP parameter and use the country that the IP address is from. If you use the TrustedParts.com API to provide results on a website, this allows you to provide regional results to each user without any effort on your part.
CurrencyCodeEnter a three-character ISO codeIf left blank, the search results default to USD.
DistributorsAdd this section to limit a search to one or more distributors. Omit this section to search all authorized distributors.
NameEnter the name of the distributorAdd separate Name elements for each distributor to search. See our List of Distributor Names for supported distributors.
InStockOnly*Set to true or falseSet to true to view in-stock results only. Set to false to view all results.
ExactMatch*Set to true or falseSet to true to view parts that match the SearchToken exactly. Set to false to include partial match results. Note: Partial match results are only available for single part number requests where the IsCrawler parameter is false or omitted. Most punctuation and spacing are ignored when determining what is an exact match. For instance, BAT-54C is an exact match for the SearchToken BAT54C.
IsCrawler*Set to true or falseSet to true if the end user is a crawler or bot (e.g. Google, Bing, Baidu). Set to false if the end user is not a crawler or if undetermined.
UseCachedDataSet to true or falseIf this parameter is not supplied or set to false, the TrustedParts.com API will provide results based on real-time stock and pricing services provided by participating distributors. This is the preferred setting since it yields the most accurate results. However, if you need extremely fast responses or need to submit a high volume of requests in a short period of time, you may set this parameter to true. This will direct the TrustedParts.com API to use an optimized search process that retrieves results from locally-cached data instead of real-time data. Note: If the IsCrawler parameter is set to true or the TrustedParts.com API detects that a request is made on behalf of a crawler, the UseCachedData parameter is ignored since results for crawlers are always retrieved from locally cached data.
UserAgent*Enter user agentFor requests made by a web site: Provide the web browser user agent of the end user or crawler who will view the results. Please ensure the accuracy of this value so that TrustedParts.com can verify the identity of users who receive results.
For requests made by an internal application instead of a web site: Provide the name of the application that is making the request and, if possible, a unique user identifier (preferably an ID number; no personally identifiable information should be supplied).
SourceIP*Enter the IP addressFor requests made by a web site: Provide the IP (Internet Protocol) address of the end user or crawler who will view the results. Please ensure the accuracy of this value so that TrustedParts.com can verify the identity of users who receive results.
For requests made by an internal application instead of a web site: Provide an external IP address used by your location. Note: Please do not provide an internal IP address for this value.
Geolocation: When the CountryCode parameter is omitted or left blank, the SourceIP parameter will be used to geolocate the request and provide regional results.

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.
