Browse top trending components, retrieve in-depth metadata, and integrate real-time component information into your sourcing and design workflows.

**Category:** Developer Tools | **Website:** [componentsearchengine.com/](https://componentsearchengine.com/) | **Docs:** [parse.bot/marketplace/c9f0e8d5-4318-4f6b-b9b2-32c3ef898591/componentsearchengine-com-api](https://parse.bot/marketplace/c9f0e8d5-4318-4f6b-b9b2-32c3ef898591/componentsearchengine-com-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/credits/componentsearchengine/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Get component details

Fetch full details for one component identified by part number and manufacturer. Returns the component description scraped from the detail page, plus rich metadata from the suggestion API including recognized parametric values (voltage, current, power ratings, package codes) and related part suggestions from other manufacturers. The metadata block may be empty when the suggestion API has no data for the given component.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `manufacturer` | string | Yes | The manufacturer name (e.g. 'onsemi'). |
| `part_number` | string | Yes | The component part number (e.g. 'BAV99'). |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/componentsearchengine/get-component-details \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"manufacturer":"<string>","part_number":"<string>"}'
```

### Get popular components

Retrieve the most popular electronic components ranked by usage count. Each component carries part number, manufacturer, component class, 3D/ECAD availability flags, and a download count reflecting design-tool usage. The response is a flat list ordered by descending count; no pagination — a single request returns all requested items.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `limit` | integer | No | Maximum number of popular components to return. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/componentsearchengine/get-popular-components \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"limit":"<integer>"}'
```

### Search components

Full-text search over electronic components by keyword or part number. Returns paginated results (up to 25 per page) parsed from HTML search results. Each result includes part number, manufacturer, description, package category, and a direct URL to the component detail page. total_results reports the server-side hit count when available.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `page` | integer | No | Page number for pagination (1-based). |
| `query` | string | Yes | Search keyword or part number. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/componentsearchengine/search-components \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"page":"<integer>","query":"<string>"}'
```
