Frequently asked questions

No. Every endpoint reads public data and needs no login or key of your own.

Pages are 1-based. Page N returns page N, and has_more tells you whether another page exists.

Each successful request uses one Scrappa credit. Failed requests are never charged and the API never answers with HTTP 429. An upstream outage returns a retryable 503.

No. Scrappa is an independent service and is not affiliated with or endorsed by Stack Overflow. It returns public Stack Overflow data as JSON.
