**Category:** Developer Tools | **Website:** [mastra.ai/models/providers](https://mastra.ai/models/providers) | **Docs:** [parse.bot/marketplace/e4c56b83-3e30-4484-92ad-0d71ffc6c8e2/mastra-ai-api](https://parse.bot/marketplace/e4c56b83-3e30-4484-92ad-0d71ffc6c8e2/mastra-ai-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/mastra/`
**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 provider models

Get detailed model information for a specific provider. Returns the provider name, description, and a list of all models with their capabilities (tools, reasoning, image, audio, video support), context window size, and pricing. The provider_slug is produced by list_providers.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `provider_slug` | string | Yes | URL slug identifying the provider (e.g. 'openai', 'anthropic', 'google'). Obtained from list_providers results. |

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

### List providers

List all AI model providers available on Mastra. Returns each provider's name, URL slug, and total model count. No pagination; all providers are returned in a single call.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/mastra/list-providers \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```
