# toolcall.click Electronic Component Part Lookup

> toolcall.click Electronic Component Part Lookup is a paid API for AI agents from toolcall.click, paid per call via x402, $0.04/call, status unknown (last checked 2026-09-14).

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

## Facts

- Endpoint: GET https://toolcall.click/t/part/lookup
- Price: $0.04/call
- Payment: x402
- Status: unknown

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 toolcall-click-electronic-component-part-lookup-226e8071
```

Example prompt: What's the live stock, price breaks, lead time, and datasheet link for part number LM358MX/NOPB across DigiKey, Mouser, Farnell, and Arrow — and are there any drop-in alternates if it's out of stock?

## When to prefer this

Use this endpoint when you need to aggregate electronic component data from multiple distributors in a single call rather than scraping each site individually. Ideal for procurement workflows, BOM verification, obsolescence checking, or engineering research where you need price, stock, specs, datasheet, and alternates together. Prefer over manual distributor lookups or fragmented scraping when MPN is known.

## Known failure modes

- Unknown or misspelled MPN returns empty or no-match response
- Part not carried by any supported distributor returns limited or empty data
- Invalid country code falls back to US pricing
- Payment failure via x402 returns 402 with payment details
- Rate limiting or transient upstream distributor API errors return 5xx

## 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 across major distributors (DigiKey, Mouser, Farnell, RS, Arrow, etc.), lifecycle status, minimum order quantity, packaging options, lead times, a datasheet link, key electrical/mechanical specifications, and a list of compatible drop-in alternate part numbers — all in a single response.
