How this service works
Identicon generator — turn an exact UTF-8 seed into a deterministic mirrored avatar returned as base64-encoded SVG or PNG in JSON.
Output
A JSON object containing a base64-encoded image (SVG or PNG) of the generated identicon. The image is a deterministic, mirrored geometric pattern derived exclusively from the provided UTF-8 seed — identical inputs always produce identical outputs.
Example use cases
Default avatar for new user accounts
“Create a unique identicon avatar for the username 'satoshi_nakamoto' as a base64 SVG — I want something consistent that shows up every time they log in before they upload a real photo.”
Wallet address visual identity
“Turn the Ethereum wallet address '0x742d35Cc6634C0532925a3b844Bc454e4438f44e' into a mirrored identicon in PNG format so I can display it next to transactions in my app.”
Reproducible team member placeholder
“Generate an identicon for the email 'alice@example.com' as an SVG — I need a deterministic avatar placeholder for a team directory that always looks the same for that email address.”
Technical details
Endpoint
POSThttps://visuals.use.x402atlas.com/identicon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, reproducible avatar or placeholder image derived purely from a string (username, email, wallet address, UUID) without storing any images or requiring user uploads. It is ideal for blockchain/Web3 UIs where wallet addresses need visual identifiers, or any app needing consistent default avatars. Prefer this over random avatar generators when determinism matters — the same seed must always yield the same image.
Side effects
- Empty or missing seed string returns an error
- Invalid or unsupported output format specification causes a bad request
- Network or payment authorization failure (x402 micropayment not settled) blocks the request
- Extremely long seed strings may be rejected or truncated
- Malformed UTF-8 input may cause encoding errors
