# Electronic Component Part Lookup

> Electronic Component Part Lookup is a paid API for AI agents from toolsmith-api.dassad10.workers.dev, paid per call via x402, $0.04/call, status unknown (last checked 2026-09-15).

Returns live distributor pricing, stock, lifecycle status, datasheet, specs, and drop-in alternates for an electronic component given its manufacturer part number (MPN).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability electronic-component-part-lookup-4e89c333
```

Example prompt: Can you look up live distributor stock and pricing for the component LM358MX/NOPB — I want to see price breaks across DigiKey, Mouser, and Farnell, plus the datasheet link, lifecycle status, and any drop-in alternates, priced for the US?

## When to prefer this

Use this endpoint when you need aggregated, real-time distributor stock and pricing for an electronic component across multiple distributors in a single call, avoiding the need to scrape DigiKey, Mouser, Farnell, RS, and Arrow separately. Ideal for procurement research, BOM costing, sourcing automation, or checking component availability and lifecycle status.

## Known failure modes

- Unknown or invalid MPN returns empty results or a 404-style error
- Distributor data temporarily unavailable may result in partial results for some sources
- Invalid country code may fall back to US pricing or return an error
- Rate limiting or payment failure (x402) returns a 402 Payment Required response
- Highly obscure or obsolete parts may have limited distributor coverage

## How this service works

Everything about an electronic component from its manufacturer part number: live distributor stock and price breaks across DigiKey, Mouser, Farnell, RS, Arrow and more, lifecycle status, MOQ, packaging, lead times, datasheet link, key specs and drop-in alternates. Optional country= for regional pricing. One call instead of checking each distributor. JSON response. $0.04 USDC per call, pay via x402, no API key.

## Output

A JSON object containing live stock levels and price breaks from multiple distributors (DigiKey, Mouser, Farnell, RS, Arrow, etc.), lifecycle status, MOQ, packaging type, lead times, a datasheet URL, key electrical specs, and a list of drop-in alternate part numbers for the queried MPN.
