Step 1: Onboard to Ondo Global Markets

To get started, reach out to onboarding@ondo.finance and let the team know you’re interested in API access. Then head to 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: 
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: 
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: 
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 for more instructions on contract interaction, and GM smart contract addresses for contract addresses.
