Render a saved template one or more times with different parameter values. Returns PNG images. **Multi-variant rendering (the common case):** pass `renders` as an array — each entry is the per-variant modifications. Great for "give me 3 versions of this card with different headlines" or "render this template for X, Y, Z". Up to 4 variants per call. All variants share the same template and size; only `modifications` differs per variant. Charged 4× for 4 variants etc. **Single render:** pass `renders` as a 1-element array. **Looking up the template:** pass either template_id (UUID) or template_name (case-insensitive). If you don't know which template to use, call list_templates first. **How modifications work:** - Pass values keyed by parameter name, e.g. { headline: "Launch day!", hero_image: "https://..." } - Missing parameters fall back to their defaults. Required parameters with no default and no value error out. - Text values are HTML-escaped. image_url values are fetched server-side and inlined as data URIs. - Static assets defined on the template (logos, etc.) are always included. **Failure semantics:** all-or-nothing credit charge. If any variant fails to render, the entire credit charge is refunded. Successful variants are still returned so you can see what worked.
