How this service works
Make a 3D AI agent from a selfie in 60 seconds. Drop one HTML tag to embed it on any website. Agents think on IBM watsonx.ai (Granite); optionally charge per chat with built-in micropayments.
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.
Example use cases
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.”
Technical details
Endpoint
POSThttps://three.ws/api/x402/vanity-verifiableWhen to prefer
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.
Side effects
- 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
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| prefix | string | Base58 characters the address must start with. Base58 excludes 0, O, I, l. Combined with suffix, max 3 characters. |
| sealTo | string | Strongly recommended. Your 32-byte X25519 public key (Base58, Base64url, or hex). When set, the secret is ECIES-sealed to it and omitted from the response — open it client-side with the matching private key. |
| suffix | string | Base58 characters the address must end with. Combined with prefix, max 3 characters. |
| clientSeed | string | Optional. Your own entropy as hex or Base58 (any length). Mixed into the seed so the server could not have predicted the result at commit time. A fresh random one is generated and revealed in the receipt when omitted. |
| ignoreCase | string | When 1/true, match the pattern case-insensitively (faster, less specific). |
