# Serverless

> Pay-as-you-go access to Wafer models through OpenAI-compatible and Anthropic-compatible APIs.

Wafer Serverless gives you pay-as-you-go access to Wafer-hosted models through the same inference endpoint used across Wafer products. Load credits, mint an API key, and pay per token with no subscription window.

## Connection Details

|                                   |                                               |
| --------------------------------- | --------------------------------------------- |
| **OpenAI-compatible endpoint**    | `https://pass.wafer.ai/v1`                    |
| **Anthropic-compatible endpoint** | `https://pass.wafer.ai/v1/messages`           |
| **Send your API key as**          | `Authorization: Bearer <key>`                 |
| **Request-scoped ZDR**            | Add `Wafer-ZDR: required` on direct API calls |

## API Capabilities

Serverless supports request-scoped privacy and advanced completion controls:

* [API Reference](/serverless/api-reference)
* [Zero Data Retention](/serverless/zero-data-retention)
* [Tokenized Completions and Constrained Decoding](/serverless/tokenized-completions)
* [Metrics API](/serverless/metrics-api)
* [Usage API](/serverless/usage-api)

## Models

Call `GET https://pass.wafer.ai/v1/models` to see the currently public Serverless catalog. Each model card includes whether the model supports ZDR.

```bash theme={null}
curl -sS "https://pass.wafer.ai/v1/models" \
  -H "Authorization: Bearer <YOUR_WAFER_API_KEY>"
```

The public catalog only lists models that are ready for general use. Some routed models may be available by allowlist before they appear in the public catalog.
