## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/parse-usito-usherbrooke-ca-api-a9fe9339/`
**Auth:** `Authorization: Bearer <LOCUS_API_KEY>`

## Endpoints

### get_all_words_for_letter

Fetches the word index for a given letter and then retrieves the full definition for each word. Combines index lookup with entry detail in one call. Use the limit parameter to cap the number of definitions fetched — omitting it returns all words for that letter (can be slow for common letters).

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `letter` | string | Yes | Single lowercase letter (a-z). |
| `limit` | integer | No | Max number of words to fetch definitions for. Omitting returns all words for that letter. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/parse-usito-usherbrooke-ca-api-a9fe9339/get_all_words_for_letter \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"letter":"<string>","limit":"<integer>"}'
```

### get_conjugation_models

Fetches the complete index of verb conjugation models available in the USITO dictionary. Each model represents a conjugation pattern that multiple verbs follow. Returns model names and slugs usable with get_verb_conjugation.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/parse-usito-usherbrooke-ca-api-a9fe9339/get_conjugation_models \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### get_verb_conjugation

Fetches the full conjugation table HTML for a given verb. If the base slug does not have a conjugation table, automatically tries the slug with '_1' suffix. Slugs from get_conjugation_models or search_words work directly. The returned HTML contains all tenses and moods in a structured table format.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `slug` | string | Yes | Verb slug (e.g. 'aimer', 'être', 'avoir'). Slugs from get_conjugation_models work directly. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/parse-usito-usherbrooke-ca-api-a9fe9339/get_verb_conjugation \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"slug":"<string>"}'
```

### get_word_entry

Fetches a word's full definition, grammatical class, phonetic transcription, and URL from its dictionary article page. The slug identifies the word uniquely and is obtained from get_word_index_by_letter or search_words.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `slug` | string | Yes | The word slug as returned by get_word_index_by_letter or search_words (e.g. 'abaca', 'chat_1', 'être_1'). |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/parse-usito-usherbrooke-ca-api-a9fe9339/get_word_entry \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"slug":"<string>"}'
```

### get_word_index_by_letter

Fetches all words/expressions starting with a given letter from the USITO dictionary index. Returns word entries with their slug, grammatical class, and gender. Pagination is handled internally — the full list for the letter is returned in one call.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `letter` | string | Yes | Single lowercase letter (a-z) to browse the dictionary index. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/parse-usito-usherbrooke-ca-api-a9fe9339/get_word_index_by_letter \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"letter":"<string>"}'
```

### search_words

Searches the USITO dictionary for words matching a query string. Returns matching entries with their slug, document type, word text, and grammatical class. Results can be used to navigate to full definitions via get_word_entry.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `query` | string | Yes | Search term (e.g. 'chat', 'aimer'). |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/parse-usito-usherbrooke-ca-api-a9fe9339/search_words \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query":"<string>"}'
```
