Frequently asked

Does ScreenshotOne's OpenAPI spec have parameter descriptions?

No. As of August 16, 2026, the live spec at api.screenshotone.com/openapi.json defines 66 parameters, and none of them — zero — carry a description or an example value. An AI agent reading the spec has only the parameter name to go on.

How much smaller is ScreenshotOne's free tier than shotanvil's?

ScreenshotOne's free tier is 100 screenshots/mo; shotanvil's is 1,000/mo — 10x larger. Verified against ScreenshotOne's own pricing page as of August 16, 2026.

Does ScreenshotOne have a pay-per-call option with no signup?

No. Every ScreenshotOne request requires an account and an API key. shotanvil supports x402 pay-per-call with zero signup.

Can I see my remaining quota or per-call cost in the response?

With shotanvil, yes — every response carries X-Quota-Remaining and X-Cost headers. ScreenshotOne's API reference does not document an equivalent.
