}About the componentsearchengine.com API
The Component Search Engine API provides 3 endpoints for querying electronic component data from componentsearchengine.com, covering part search, detailed metadata retrieval, and popularity rankings. The search_components endpoint returns paginated results up to 25 components per page, while get_component_details exposes rich metadata including recognized parameter values, manufacturer details, and related component suggestions for any specific part number and manufacturer pair.
Endpoints and Data Coverage
The API exposes three endpoints. get_popular_components returns a ranked list of components ordered by usage count, with each record carrying fields like partId, partNumber, manufacturer, ecad, have3d, class, samacStatus, count, totalScore, score, and last. An optional limit parameter controls how many results come back. This is useful for quickly identifying which parts are most actively referenced across the platform.
search_components accepts a required query string (keyword or part number) and an optional page integer for pagination. Each page returns up to 25 components, and the response includes a results array alongside a total_results count so you can calculate page depth before iterating.
Component Detail Retrieval
get_component_details requires both part_number and manufacturer as inputs and returns a single component object with part_number, manufacturer, description, and a metadata block. That metadata block contains recognized parameter values — the structured electrical and physical specs parsed from the component record — plus a suggestions array of related components. The ecad and have3d flags (also visible in the popularity endpoint) signal whether CAD assets such as PCB footprints and 3D models are associated with a part, though the asset files themselves are not returned by these endpoints.
SAMAC Status and Asset Flags
Several response fields are specific to componentsearchengine.com's data model. samacStatus appears in the popularity endpoint and indicates the component's status within the SAMAC (Standard for the Automated Management of Alternate Components) framework. The ecad flag indicates ECAD library asset availability, and have3d indicates 3D model availability. These flags are useful for filtering components during BOM preparation or library management workflows where CAD-ready parts are a prerequisite.
- Build a BOM validation tool that checks part numbers against known manufacturer records using
get_component_details. - Track trending components by usage count with
get_popular_componentsto inform component selection for new designs. - Implement a component autocomplete search in a PCB design tool using
search_componentswith keyword queries. - Filter search results to only ECAD-ready parts by inspecting the
ecadflag insearch_componentsresults. - Retrieve recognized parameter values from
get_component_detailsmetadata to populate a parametric comparison table. - Identify components with 3D models available by checking the
have3dfield before importing into a mechanical CAD workflow. - Paginate through component search results programmatically using the
pageparameter andtotal_resultscount.
| Tier | Price | Credits/month | Rate limit |
|---|---|---|---|
| Free | $0/mo | 100 | 5 req/min |

One credit = one API call regardless of which marketplace API you call. Exceeding the rate limit returns a 429 response. Authenticate with the X-API-Key header.
Does componentsearchengine.com have an official developer API?+
What does `get_component_details` return beyond basic part information?+
metadata object that includes recognized values — structured electrical and physical parameters extracted from the component record — and a suggestions array of related components. The description field provides a text summary of the part. The ecad and have3d flags indicate whether CAD assets are associated, though asset file downloads are not included in the response.Does the API return pricing or distributor stock data for components?+
How does pagination work in `search_components`?+
total_results integer alongside the results array, so you can compute the number of available pages before iterating. Pass the page integer parameter to step through results. If total_results is 75, there are three pages of results at most.Can I retrieve the actual ECAD library files or 3D model files through this API?+
ecad and have3d fields indicate that assets exist for a component, but the API does not return the asset files themselves. You can fork this API on Parse and revise it to add an endpoint that fetches or links to the downloadable library files.
