**Category:** Developer Tools | **Website:** [instantdomainsearch.com/](https://instantdomainsearch.com/) | **Docs:** [parse.bot/marketplace/ab14e50c-5f76-4521-a6c2-6b6611bb1e1e/instantdomainsearch-com-api](https://parse.bot/marketplace/ab14e50c-5f76-4521-a6c2-6b6611bb1e1e/instantdomainsearch-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/instantdomainsearch/`
**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

### Check domains

Check the availability status of specific fully-qualified domain names. Returns availability (available, inuse, reserved, unsupported) and trust level for each domain. Useful for verifying whether particular domains are registered or available for purchase.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `domains` | string | Yes | Comma-separated list of fully-qualified domain names to check (e.g. 'example.com,example.net,mybrand.io'). |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/instantdomainsearch/check-domains \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"domains":"<string>"}'
```

### Search domains

Search domain availability for a given name across multiple TLD extensions. Returns registration status, premium pricing, and aftermarket listing information for each TLD. Results are returned in a single page; use the limit parameter to cap the number of domains checked.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `limit` | integer | No | Maximum number of results to return. |
| `query` | string | Yes | Domain name to search (without TLD extension), e.g. 'techstartup', 'myshop'. |
| `tlds` | string | No | Comma-separated list of TLD extensions to check (e.g. 'com,net,org,io,app'). When omitted, searches across 70+ popular TLDs including com, net, org, ai, io, xyz, app, shop, info, co, dev, tech, and many more. |

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