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/exhibitors-cphi/`
**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.

Full call contract: https://docs.paywithlocus.com/api-reference/introduction

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

## Endpoints

### Get exhibitor details

Fetch full details for a specific exhibitor by company ID. Returns contact information, employee count, address, website, stand number, country, categories, and company description. The company_id is obtained from list_exhibitors results.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `company_id` | string | Yes | The exhibitor company ID (numeric string). Obtain from list_exhibitors results. |
| `event_id` | string | No | The event ID for the target CPHI event. |
| `site_id` | string | No | The site ID for the CPHI portal. |

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

### List exhibitor names

Compile a complete list of all exhibitor company names for a given event. Returns all names in a single response without pagination. Useful for quick lookups or autocomplete without the overhead of fetching full profiles.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `event_id` | string | No | The event ID for the target CPHI event. |
| `site_id` | string | No | The site ID for the CPHI portal. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/exhibitors-cphi/list-exhibitor-names \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"event_id":"<string>","site_id":"<string>"}'
```

### List exhibitors

Fetch exhibitor profiles with pagination. Returns detailed exhibitor data including company name, website, employees, phone, address, country, stand number, categories, and description. Each page fetches full details for each exhibitor from both JSON and HTML sources; larger page sizes are slower proportionally. Offset-based: pass offset and limit to page through results manually.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `event_id` | string | No | The event ID for the target CPHI event. |
| `limit` | integer | No | Max number of exhibitors to return per page. |
| `offset` | integer | No | Starting index for pagination. |
| `site_id` | string | No | The site ID for the CPHI portal. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/exhibitors-cphi/list-exhibitors \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"event_id":"<string>","limit":"<integer>","offset":"<integer>","site_id":"<string>"}'
```
