Serve a signed image URL
Generate
Serve a signed image URL
The OG-image primitive: a signed GET that 302s to a rendered, immutable PNG.
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.Path Parameters
Design preset slug, optionally version-pinned ("promo-bold@3")
Query Parameters
Export profile (default facebook_16x9 — 1200×630, the OG size)
Available options:
png, jpg Deterministic seed override (digits)
Account attribution — embedded and signed at mint time; do not construct manually
URL signature (from POST /sign)
Expiry timestamp (Unix ms); absent = non-expiring
Response
Redirect to the rendered image (immutable CDN URL)
