## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability imagemeta-seo-metadata-writer-5dbcc89d -d '<json body>'
```

Example prompt: Take this product image (base64 encoded) and write the SEO metadata into it — set the title to 'Red Leather Wallet', alt to 'Close-up of a slim red leather bifold wallet', keywords to 'wallet, leather, red, slim, bifold', author to 'Jane Smith', copyright to '© 2024 Acme Co', and description to 'Premium handcrafted red leather wallet'.

## When to prefer this

Choose this endpoint when you need to embed SEO or descriptive metadata (title, alt, keywords, author, copyright, description) directly into an image file without re-encoding or degrading image quality. It is ideal for pre-publish workflows that require standards-compliant image metadata, digital asset management pipelines, or accessibility tagging. Prefer this over server-side CMS metadata fields when the metadata must travel with the image file itself.

## Known failure modes

- Invalid or malformed base64 image string — returns an error indicating the image could not be decoded
- Unsupported image format (not JPEG, PNG, or WebP) — returns an error
- HTTP 402 on first attempt with x402 payment required — agent must handle payment and retry
- Missing required fields — call may succeed with partial metadata or return a validation error
- Image too large — may time out or return a size-limit error

## How this service works

Write SEO metadata into a JPEG, PNG or WebP image and return the modified image. The picture is never re-encoded and existing metadata of the same kind is replaced, not duplicated. Paid per successful call over x402: the first attempt answers HTTP 402 with the price; a failed call is not charged.

## Output

The modified image file (JPEG, PNG, or WebP) is returned with the specified SEO metadata fields embedded directly into it. The image pixel data is never re-encoded, so there is no quality loss. Any previously existing metadata of the same types is replaced rather than duplicated.
