# three.ws Vanity Solana Address Generator (Verifiable)

> three.ws Vanity Solana Address Generator (Verifiable) is a paid API for AI agents from three.ws, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Generates a vanity Solana wallet address matching a custom prefix/suffix pattern, with a cryptographically verifiable commitment receipt and optional ECIES-sealed private key delivery.

## 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 three-ws-vanity-solana-address-generator-verifiable-85f7d738 -d '<json body>'
```

Example prompt: Generate me a vanity Solana address that starts with 'Sol' and ends with 'x' — seal the private key to my X25519 public key 5KYBxyz123abc456def789ghi (Base58) so only I can open it, and mix in my client entropy 'a3f9b2c1d4e5' for extra proof.

## When to prefer this

Choose this endpoint when you need a Solana vanity address with cryptographic proof-of-fairness (commitment scheme) and optional secure private key delivery via ECIES. It is distinctly superior to naive vanity grinders when auditability matters — the SHA-256 commitment prevents the server from cherry-picking results. Prefer it over local grinding when you lack compute resources or need the sealed-key delivery feature. Best when the user wants a short (1-3 char) prefix/suffix pattern and needs verifiable provenance of the generated keypair.

## Known failure modes

- Pattern too long or contains invalid Base58 characters (0, O, I, l) — returns 400 error
- Combined prefix+suffix exceeds 3 characters — returns 400 validation error
- Payment not received or insufficient USDC — returns 402 Payment Required
- Grinding timeout if pattern is too rare — may return timeout or partial error
- Invalid sealTo public key format — returns 400 error
- Server-side seed commitment mismatch on retry — indicates internal error

## Output

Returns a JSON receipt containing the matched Solana Base58 public key, a SHA-256 commitment (made before grinding), the revealed server seed for commitment verification, an Ed25519 signature over the receipt, the winning candidate index, attempt count, duration, and either the raw secret key bytes or an ECIES-sealed envelope (if sealTo was provided). Also includes a verifyUrl for independent on-chain verification.
