# Your first request

Start with the public endpoints. No API key required.

## See what the deployment supports

```bash
curl https://api.andromedainfra.pro/capabilities
```

The response tells you which engines are wired, which optional features are enabled (identity, recovery), how MCP is exposed, and how many routes are available. Read this before assuming a feature is present; identity and recovery in particular are opt-in per deployment.

## Read the pricing catalogue

```bash
curl https://api.andromedainfra.pro/v1/pricing
```

This lists the operations and their costs so you can plan spend without an API key. See [Pricing catalogue](/hub/andromeda/pricing/catalogue.md).

## Fetch the API schema

```bash
curl https://api.andromedainfra.pro/openapi.json
```

The OpenAPI 3.1 document is the canonical description of every request and response. Feed it to a code generator (see [OpenAPI codegen](/hub/andromeda/sdks-and-tooling/codegen.md)) or explore it in the [OpenAPI explorer](/hub/andromeda/api-reference/openapi.md).

## Then authenticate

Once you have a key (see [Get an API key](/hub/andromeda/getting-started/api-key.md)), estimate the cost of an operation:

```bash
curl -X POST https://api.andromedainfra.pro/v1/pricing/estimate \
  -H "X-Api-Key: $ANDROMEDA_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "operations": ["ika.dkg.submit", "ika.sign.submit"] }'
```

If that returns a result, your key works. Next: [Create a dWallet](/hub/andromeda/getting-started/create-dwallet.md).
