API Keys - Struct Docs

API keys are used to authenticate every request to the Struct API. Each key is scoped to an organisation and inherits its plan’s rate limits and credit allowance.

Creating an API Key

Open API Keys

Navigate to the API Keys section in your organisation’s dashboard.

Generate a key

Click Create Key, give it a descriptive name (e.g. production, staging), and confirm.

Copy your key

Your full API key is shown once at creation. Copy it and store it somewhere secure.

API keys are only displayed in full once. If you lose a key, you’ll need to revoke it and create a new one.

Using Your API Key

Include your API key in the X-API-Key header on every request.

curl https://api.struct.to/v1/polymarket/market \
  -H "X-API-Key: YOUR_API_KEY"

const response = await fetch("https://api.struct.to/v1/polymarket/market", {
  headers: {
    "X-API-Key": "YOUR_API_KEY",
  },
});

import requests

response = requests.get(
    "https://api.struct.to/v1/polymarket/market",
    headers={"X-API-Key": "YOUR_API_KEY"},
)

Managing Keys

From the API Keys page you can:

Rename a key to keep your list organised
Revoke a key to immediately disable it. Any requests using that key will return 401 Unauthorized

There is no limit on the number of API keys per organisation. Use separate keys for different environments or services so you can revoke them independently.

Security Best Practices

Never expose API keys in client-side code or public repositories
Use environment variables or a secrets manager to store keys
Rotate keys periodically by creating a new key, migrating your services, then revoking the old one
Use separate keys for production and development
