Credit Parky
The rule
The API is free, including on commercial sites, on one condition: every page that shows Parky data carries a visible link to parkypass.com. It must be on the page itself, not only inside an iframe. How you mark up the link (for example any rel attribute) is up to you.
Rendering it
Render attribution.text linked to attribution.url from the latest response or stream message (a snapshot or changes message carries that park's page), and use https://parkypass.com/ until the first one arrives.
// After each response, or each snapshot or changes message:credit.href = data.attribution.url; // that park's or ride's page on parkypass.comcredit.textContent = data.attribution.text; // "Live data from parkypass.com"Without JavaScript, this static link is enough:
<a href="https://parkypass.com/">Live data from parkypass.com</a>The rest of the terms
Don’t resell the raw data or present it as your own feed, cache each response for at least its Cache-Control time, and keep within your limits. Parky can revoke keys that break these terms. The full text is in the Terms of Use.
