SDK Wallet Operations
Initialize and configure the BankrClient with proper wallet setup.
Two-Wallet System
| Wallet | Purpose | Required |
|---|---|---|
Payment (privateKey) | Signs x402 micropayments ($0.01/request) | Yes |
Context (walletAddress) | Receives swapped tokens, NFTs | No (defaults to payment wallet) |
Basic Setup
import { BankrClient } from "@bankr/sdk";
const client = new BankrClient({
privateKey: process.env.BANKR_PRIVATE_KEY as `0x${string}`,
});
const result = await client.promptAndWait({
prompt: "What are my balances?",
});
Separate Wallets (Recommended)
For enhanced security, use different wallets for payments and receiving:
const client = new BankrClient({
// Hot wallet with minimal USDC for payments
privateKey: process.env.PAYMENT_WALLET_PK as `0x${string}`,
// Cold/trading wallet receives tokens
walletAddress: process.env.RECEIVING_WALLET,
});
Configuration Options
| Option | Type | Required | Description |
|---|---|---|---|
privateKey | 0x${string} | Yes | Payment wallet private key |
walletAddress | string | No | Override receiving wallet |
baseUrl | string | No | API endpoint (default: production) |
timeout | number | No | Request timeout ms (default: 600000) |
SDK Methods
| Method | Description |
|---|---|
promptAndWait() | Submit prompt and wait for result |
prompt() | Submit prompt, return immediately |
pollJob() | Poll until job completes |
getJobStatus() | Check job status once |
cancelJob() | Cancel pending/processing job |
getWalletAddress() | Get context wallet address |
Per-Request Override
// Override wallet for a single request
const result = await client.promptAndWait({
prompt: "Swap 0.1 ETH to USDC",
walletAddress: "0xDifferentWallet...",
});
Environment Setup
# Required
BANKR_PRIVATE_KEY=0x...your_payment_wallet_key...
# Optional
BANKR_WALLET_ADDRESS=0x...your_receiving_wallet...
Security Best Practices
- Never commit private keys - Use environment variables
- Minimize payment wallet balance - Keep only $1-2 USDC
- Use separate wallets - Payment (hot) vs receiving (cold)
- Rotate keys periodically - If payment wallet compromised

Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
