# Purple Flea Public Wallet
> Multi-chain HD wallet API for AI agents. Generate wallets, check balances, send, and swap across chains. No KYC. Non-custodial. Pure API.

## What This Does
AI agents create non-custodial BIP-39 HD wallets with one API key. Manage crypto across 6 chains. Cross-chain swaps via Wagyu aggregator.

## Supported Chains
- Wallet generation: Ethereum, Base, Solana, Bitcoin, Tron, Monero
- Balance check + send: Ethereum, Base, Solana, Bitcoin, Tron, Monero (XMR requires view_key for balance, spend_key for send)
- Cross-chain swaps: Ethereum, Base, BSC, Arbitrum, Solana, Bitcoin, Monero, HyperEVM

## Quick Start
```bash
# 1. Register
curl -X POST https://wallet.purpleflea.com/v1/auth/register -H "Content-Type: application/json" -d '{}'

# 2. Create HD wallet (mnemonic shown ONCE — save it securely)
curl -X POST https://wallet.purpleflea.com/v1/wallet/create \
  -H "Authorization: Bearer pk_live_..."

# 3. Check balance (Base USDC)
curl "https://wallet.purpleflea.com/v1/wallet/balance/0xYourAddress?chain=base" \
  -H "Authorization: Bearer pk_live_..."

# 4. Get deposit address for your wallet
curl "https://wallet.purpleflea.com/v1/wallet/deposit-address?chain=base" \
  -H "Authorization: Bearer pk_live_..."

# 5. Cross-chain swap quote (Base USDC → Solana USDC)
curl "https://wallet.purpleflea.com/v1/wallet/swap/quote?from_chain=base&to_chain=solana&from_token=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&to_token=EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v&amount=50" \
  -H "Authorization: Bearer pk_live_..."

# 6. Execute swap
curl -X POST https://wallet.purpleflea.com/v1/wallet/swap \
  -H "Authorization: Bearer pk_live_..." \
  -H "Content-Type: application/json" \
  -d '{"from_chain":"base","to_chain":"solana","from_token":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","to_token":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","amount":"50","to_address":"YourSolAddress"}'
```
