**Category:** Education | **Website:** [verbformen.com/](https://verbformen.com/) | **Docs:** [parse.bot/marketplace/0fe37274-1f87-4019-9e61-e0fd28e96eb3/verbformen-com-api](https://parse.bot/marketplace/0fe37274-1f87-4019-9e61-e0fd28e96eb3/verbformen-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/verbformen/`
**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

### Search

Search for German words by keyword and/or exact CEFR level (A1-C2). The level parameter is an exact match filter; a word only appears in results if it is classified at that specific level. Returns grammatical info, translations, IPA pronunciations, and detail URLs. Results may be empty if no words match the query at the specified level.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `level` | string | No | Exact CEFR level filter. Accepted values: A1, A2, B1, B2, C1, C2. |
| `limit` | integer | No | Maximum number of results to return. Omitting returns all matching results. |
| `query` | string | No | Search keyword or starting letter (e.g. 'haben', 'A'). Omitting returns all words at the given level. |

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