The TrustedParts API: A Complete Guide for Engineers and Procurement Teams
Zenode.ai
Counterfeit electronic components are not a theoretical risk. They are a documented, recurring problem that has compromised military helicopters, missile defense systems, and cargo aircraft. A U.S. Senate Armed Services Committee investigation identified roughly 1,800 cases of suspect counterfeit parts in the Department of Defense supply chain, totaling over one million individual components. Counterfeits cost U.S. semiconductor companies more than $7.5 billion annually in lost revenue.
The problem isn't limited to defense. Any organization sourcing electronic components faces the question: is the part you're buying actually what it claims to be? Is the distributor selling it authorized by the manufacturer to do so?
TrustedParts was built specifically to answer that question. It's the only component inventory aggregator that exclusively lists parts from authorized distributors -- every single listing verified against manufacturer authorization records. And its API is completely free.
If you're building procurement tools, ERP integrations, or sourcing workflows, the TrustedParts API deserves a serious look. Here's what you need to know.
Where TrustedParts Comes From
TrustedParts is owned and operated by the Electronic Components Industry Association (ECIA), the trade association representing electronic component manufacturers, authorized distributors, and manufacturer representatives. ECIA was formed in 2011 through a merger of the National Electronic Distributors Association and the Electronic Components Association.
The platform launched in 2010 under the name ECIAauthorized.com. The original purpose was straightforward: give engineers and purchasing professionals a single place to search inventory across authorized distributors, eliminating the need to check each distributor's site individually.
In 2016, the platform expanded globally, adding support for local languages and currencies across key markets. Then in May 2020, ECIA rebranded the site to TrustedParts.com. The name change was deliberate -- "ECIAauthorized" implied the site was restricted to ECIA member distributors, which limited adoption outside the Americas. "TrustedParts" better communicates the actual value proposition: every part listed comes from an authorized source.
The rebranding also opened participation to non-ECIA-member distributors, which expanded the distributor network and improved coverage. This wasn't just marketing -- it was a strategic decision to grow the platform's usefulness by prioritizing coverage over membership exclusivity.
Understanding the ECIA ownership matters because it explains why the API is free, why the data only includes authorized sources, and why the platform exists at all. This isn't a startup trying to build a business around component data. It's a trade association fulfilling its mission to promote the authorized distribution channel.
What You Actually Get
The TrustedParts API is a REST endpoint that returns authorized distributor inventory for the parts you query. The scope is focused and well-defined.
Coverage is substantial. The platform aggregates inventory from more than 80 vetted distributors, covering over 26 million unique part numbers from 2,000+ manufacturers. Total in-stock SKUs exceed 54 billion. That's not as broad as aggregators that include broker and independent distributor inventory, but for authorized-only sources, the coverage is comprehensive.
Data fields include real-time stock levels and pricing, product descriptions, packaging details, minimum order quantities, lead times, and links to datasheets and product pages. The practical information a procurement team needs to make a buying decision.
Batch queries support up to 50 parts per request. If you're processing a BOM and need to check authorized availability across all line items, you can do it in batches rather than one part at a time.
Filtering lets you narrow results by country, manufacturer, exact match versus partial match, and other criteria. If you only care about distributors serving a specific region, or you want results from a particular manufacturer's authorized channel, the API handles that.
Verification is where TrustedParts differs from every other aggregator. Before a distributor can list inventory on the platform, they must provide proof of authorization from the manufacturer -- for each manufacturer, in each region. TrustedParts administrators review, research, and approve each authorization request. This isn't a self-serve listing. It's a verified, audited process.
The API Experience
The technical implementation is deliberately simple. The API receives search requests via HTTPS POST and supports both JSON and XML for requests and responses. The endpoint is https://api.trustedparts.com/v2/search.
Authentication requires a Company ID and API Key, which you obtain by requesting access through your TrustedParts.com account. There's no OAuth flow, no token refresh, no complex credential management. You include your credentials with each request and get a response.
If you've worked with enterprise component data APIs -- particularly GraphQL-based ones like Nexar that require understanding query schemas, client libraries, and pagination mechanics -- the simplicity here is refreshing. A developer can be making API calls within minutes of receiving credentials, not hours.
The API also has interactive Swagger documentation where you can test requests directly with your API key. Expand the POST endpoint, adjust parameters, click Execute. You see exactly what you'll get before writing any integration code.
For teams that need a visual integration rather than a code-level one, TrustedParts also offers a Distributor Search Solution (DSS) -- essentially a widget you can embed on your site. But for anyone building real procurement workflows, the API is the path.
The Price: Free, and Why That Matters
The TrustedParts API is completely free for almost all use cases. No per-query charges. No monthly subscription. No tiered pricing based on data access levels.
This is unusual in the component data space, and it's worth understanding why.
Most component data APIs have become expensive. Nexar's paid tiers start around $500/month for limited data, climbing above $2,000/month for full access. SiliconExpert uses enterprise-only pricing. Even the Octopart API, which was once cheap or free, now sits behind Nexar's paywall. The trend across the industry has been toward higher prices and more restrictive terms.
TrustedParts moves in the opposite direction because the incentive structure is different. ECIA is a trade association whose members -- the authorized distributors -- benefit when purchasing professionals use the authorized channel. Every query through TrustedParts is a potential purchase routed to an authorized distributor rather than a broker or gray market source. The API pays for itself by driving business to the member network.
This means the free pricing isn't a trial, a loss leader, or a temporary promotion. It's the business model. The API exists to make authorized sourcing easier, and charging for it would defeat the purpose.
For engineering teams and procurement organizations, the practical implication is clear: you can add authorized inventory verification to any workflow at zero marginal cost. There's no budget conversation required. No procurement process to navigate. No contract to negotiate.
Where TrustedParts Excels
The platform's strengths flow directly from its focused mission.
Supply chain integrity is the core value. If your organization operates in defense, aerospace, medical devices, or automotive, supply chain integrity isn't a nice-to-have -- it's a regulatory requirement. Standards like SAE AS6496 specifically address counterfeit component avoidance and call for sourcing from authorized distributors. TrustedParts gives you a programmatic way to verify authorization status, which matters for compliance documentation and audit trails.
ERP and procurement integration is the primary use case. The API was designed to plug into the tools purchasing teams already use. Quote tools, ERP systems, and internal procurement platforms can query TrustedParts to show authorized availability alongside pricing from other sources. The batch query capability (50 parts at a time) supports BOM-level verification workflows.
Simplicity reduces integration cost. REST with JSON. API key authentication. Clear documentation. No GraphQL learning curve, no OAuth complexity, no pagination quirks. A junior developer can build a working integration in an afternoon.
Coverage across the authorized channel is comprehensive. With 80+ vetted distributors, TrustedParts covers the major players -- Arrow, Avnet, DigiKey, Mouser, Future Electronics, and dozens of others -- along with regional distributors that broader aggregators might miss. If a part is available from an authorized source, TrustedParts is likely to surface it.
What's Missing
Being honest about TrustedParts' limitations matters more than overselling its strengths. The gaps are real, and they define when you need additional tools.
No component selection or discovery. TrustedParts is a lookup tool. You provide a part number, it tells you where to buy it from an authorized source. It cannot help you figure out which part to buy in the first place. There's no parametric search by engineering requirements, no understanding of application context, and no way to describe what you need in natural language. If you don't already know the exact MPN, TrustedParts has limited utility.
No alternatives or cross-references. When a part is unavailable -- out of stock, discontinued, or allocation-constrained -- TrustedParts doesn't suggest substitutes. You see zero results and that's it. Finding a functionally equivalent alternative from a different manufacturer is entirely your problem. During the 2020-2022 component shortage, this limitation was particularly painful. Engineers knew their parts existed somewhere; they needed help finding what to use instead.
No intelligence layer. The API returns raw inventory data. There's no ranking, no recommendation, no analysis. It can't tell you "this distributor has better pricing at your volume" or "this alternative is pin-compatible." You get data; you make decisions.
Authorized-only means incomplete visibility. This is the flip side of the platform's core strength. During supply constraints, authorized channel inventory sells out first. Parts may be available from reputable independent distributors or as excess inventory from OEMs, but none of that appears in TrustedParts. For organizations with strict authorized-only procurement policies, this is fine. For those who need to find parts wherever they are, it's a blind spot.
Designed for purchasing, not competitive analysis. The API is explicitly positioned for procurement use cases. Using it to analyze competitor pricing strategies, benchmark distributor performance, or conduct market research isn't the intended purpose and may run afoul of terms.
Who Should Use It
TrustedParts makes the most sense for organizations where supply chain integrity is either a regulatory requirement or a serious operational concern.
Defense and aerospace contractors operating under SAE AS6496 or similar standards need documented proof that components come from authorized sources. TrustedParts provides that verification programmatically, which supports compliance workflows and audit documentation.
Medical device manufacturers under FDA quality system requirements face similar sourcing scrutiny. While the regulations are structured differently than defense standards, the underlying principle -- know your supply chain -- applies equally.
Procurement teams building authorized-only workflows benefit from a free API that plugs into ERP and quoting systems. If your organization has decided that all components must come from authorized distributors, TrustedParts lets you enforce that policy at the tool level rather than relying on manual verification.
Anyone building BOM verification tools should consider TrustedParts as a data source. The batch query capability, combined with free pricing, makes it practical to add authorized-availability checks to BOM management workflows without increasing costs.
When to Look Elsewhere
TrustedParts solves a specific problem well. Several adjacent problems require different tools.
Component discovery and selection -- figuring out which part to use based on engineering requirements -- is outside TrustedParts' scope entirely. If you're in the design phase and need to evaluate options, compare specifications, or understand tradeoffs between alternatives, you need a discovery tool, not an inventory lookup.
Cross-reference and alternative finding during shortages or obsolescence events requires intelligence that TrustedParts doesn't provide. When your primary part is unavailable, knowing it's out of stock at all authorized distributors is useful information but doesn't solve the problem. You still need to find a substitute.
Multi-source visibility including independent distributors and broker inventory isn't available through TrustedParts by design. If your procurement policy allows purchasing from reputable independents when authorized sources are exhausted, you'll need additional data sources.
Datasheet-level technical specifications aren't part of what TrustedParts returns. You get product descriptions and datasheet links, but not parsed, structured specification data that would support engineering analysis or parametric comparison.
Where Zenode Fits In
TrustedParts and Zenode answer fundamentally different questions in the component workflow.
TrustedParts answers: "Where can I buy this part safely?" You have a part number. You need authorized sources. TrustedParts returns verified inventory from authorized distributors at no cost.
Zenode answers: "What part should I use?" You have engineering requirements. You need to find the right component. Zenode's Discovery engine accepts natural language queries, understands application context, and returns ranked results with explanations. When a part becomes unavailable, the Alternatives engine suggests substitutes with explained tradeoffs -- not just "similar specs" but "here's what's different and why it might or might not work for your application."
These aren't competing tools. They address different stages of the same workflow.
In practice, the combination works like this: you use Zenode to discover and select the right components during design, leveraging AI-powered search and datasheet-grounded specifications to make informed decisions. Then you use TrustedParts to verify that your selections are available from authorized distributors before committing to a design or placing orders. During production, when parts go end-of-life or face supply constraints, you return to Zenode to find intelligent alternatives, then verify authorized availability through TrustedParts again.
Discovery and selection on one side. Authorization verification on the other. Both are necessary; neither alone is sufficient.
