# Quickstart

> Get started with the Ondo Global Markets API in minutes.

## Step 1: Onboard to Ondo Global Markets

To get started, reach out to [onboarding@ondo.finance](mailto:onboarding@ondo.finance) and let the team know you're interested in API access. Then head to [app.ondo.finance](https://app.ondo.finance) to begin the onboarding process. The Ondo team will follow up with instructions to get your API keys.

## Step 2: Get Your First Price Quote

Once you have your API key, try fetching the current price for TSLAon:

```bash theme={null}
curl -X GET "https://api.gm.ondo.finance/v1/assets/prices/TSLAon" \
  -H "x-api-key: YOUR_API_KEY"
```

All requests are authenticated via the `x-api-key` header.

## Step 3: Request a Soft Quote

A soft quote provides a non-binding price estimate without impacting your trading limits — useful for displaying pricing in a UI or validating quotes before committing:

```bash theme={null}
curl -X POST "https://api.gm.ondo.finance/v1/attestations/soft" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "symbol": "TSLAon",
    "side": "buy",
    "notionalValue": "1000",
    "duration": "short"
  }'
```

## Step 4: Request a Mint Attestation

When you're ready to execute, request a binding mint attestation. This creates a signed payload that authorizes an on-chain mint:

```bash theme={null}
curl -X POST "https://api.gm.ondo.finance/v1/attestations" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "symbol": "TSLAon",
    "side": "buy",
    "notionalValue": "1000",
    "duration": "short"
  }'
```

The response includes key fields such as `attestationId`, `signature`, and `expiration` that you'll need for the on-chain transaction.

## Step 5: Submit On-Chain

Take the attestation `signature` from the response and submit it to the Ondo GM smart contract along with USDC (or another supported stablecoin) to atomically mint your tokens. See [Smart contract reference](/api-reference/smart-contracts) for more instructions on contract interaction, and [GM smart contract addresses](/addresses#ondo-global-markets) for contract addresses.
