# Product API quickstart

> Create a key, list your agents, and start work through the Darwin Product API.

## 1. Create a Darwin account

Sign in or create an account at [darwin.so](https://darwin.so). An account owns a personal agent and can hold memberships in business agents.

## 2. Create an API key

Open [Developer settings](https://darwin.so/settings?tab=developer), create a key, and select only the scopes your client needs.

<Warning>
  Darwin shows the secret once. Keep it in a server-side secret manager and never ship it in browser or mobile code.
</Warning>

```bash theme={null}
export DARWIN_API_KEY="darwin_..."
```

## 3. List accessible agents

```bash theme={null}
curl https://api.darwin.so/api/v1/agents \
  --header "Authorization: Bearer $DARWIN_API_KEY"
```

## 4. Create work

```bash theme={null}
curl https://api.darwin.so/api/v1/goals \
  --request POST \
  --header "Authorization: Bearer $DARWIN_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
    "mode": "BUY",
    "intent": "Source 12 lightweight laptops that meet our IT requirements."
  }'
```

Darwin may return clarification or approval work before execution. Clarification is free. Billable execution begins only after the customer approves a dollar-denominated goal quote and Darwin reserves its maximum authorization from the Agent Wallet.
