Authentication
Almost all requests require an API key, sent in thex-api-key header:
key query parameter (?key=YOUR_API_KEY) when setting headers isn’t practical — for example in RSS readers.
Get your API key from Settings → API & Monitoring in the Site Spy dashboard and use the Copy Key button to copy it to your clipboard.
Quick examples
Rate limits
Rate limits are enforced per API key. Exceeding the limit returns HTTP429. The MCP server uses the same limits.
