Sending a file

Endpoints that take an image accept any of:

multipart/form-data with the image in the file field, plus options as form fields
JSON {"url": "https://…"} pointing at a public image (private/internal addresses are refused)
JSON {"base64": "…"} (a data: URL prefix is fine)

401	`UNAUTHORIZED`	Missing or invalid `X-API-Key`
413	`TOO_LARGE`	The file is over the size limit
429	—	Plan quota or rate limit reached (see the `X-RateLimit-*` headers)
