GET
Serve a signed image URL
Drop the URL straight into an og:image meta tag, an <img> src, or a no-code tool — it authenticates by signature, not headers. Mint URLs with sign first. Rendering is deterministic and cached: the same URL never renders twice, and only the first render of a unique URL costs a credit.
