Octopart API

Shopping / API Key Intermediate HTTPS
Varies by plan (check documentation)

Overview

Octopart is an electronic component search engine, and its API gives you access to detailed part data including pricing from hundreds of distributors, stock availability, datasheets, and technical specifications. You query the API using GraphQL, which lets you request exactly the fields you need for BOM management, sourcing automation, or component research tools. It is an essential API for hardware engineers and procurement teams.

💡

Beginner Tip

Octopart uses GraphQL, not REST, so all requests are POST requests to a single endpoint with a JSON body containing your query. Start with a simple part search by manufacturer part number to understand the response structure before building multi-part queries.

Available Data

Octopart data via REST API
JSON-formatted response data
Requires API key authentication

Example Response

JSON Response
{
  "status": "success",
  "data": {
    "result": "Data from Octopart",
    "description": "Electronic part data for manufacturing, design, and sourcing",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Field Reference

part.name Manufacturer part number for the electronic component
part.manufacturer.name Name of the company that manufactures the component
part.short_description Brief technical description of the component function and type
part.sellers List of authorized distributors selling this component with their pricing and stock levels
part.best_datasheet.url URL to the most relevant PDF datasheet for the component
part.category.name Component category such as Resistors, Capacitors, or Microcontrollers

Implementation Example

// ⚠️ Note: This URL may be a documentation page. Check official docs for actual API endpoint.
const url = "https://octopart.com/api/v4/reference";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

401 Unauthorized The API token is missing or incorrect in the request header
Pass your API key as a token header in every POST request to the GraphQL endpoint
GraphQL field error: unknown field Your GraphQL query references a field that does not exist in the Octopart schema
Use the schema reference at octopart.com/api/v4/reference to check valid field names before writing your query
Empty results for known part The search term is too specific or uses an unofficial variant of the part number
Try shortening the part number or removing suffix characters; Octopart normalizes part numbers so minor variations may not match
