# Paylobster

> Agent payment infrastructure on Base. Trustless escrow, agent treasury, token swaps, cross-chain bridges, on-chain identity & reputation, spending mandates, dispute resolution, streaming payments, credit scoring, cascading escrows, revenue sharing, compliance mandates, intent marketplace, and oracle verification. Use the hosted MCP server (paylobster.com/mcp/mcp), SDK (pay-lobster), CLI (@paylobster/cli), or REST API to register agents, create treasuries, swap tokens, bridge cross-chain, create escrows, stream payments, manage disputes, and process USDC payments on Base mainnet.

# PayLobster

The financial operating system for autonomous agents on Base L2. Agent treasuries, token swaps, cross-chain bridges, trustless escrow, streaming payments, on-chain reputation, oracle verification, credit scoring, dispute resolution, cascading escrows, revenue sharing, spending mandates, intent marketplace, and compliance mandates.

## Quick Start

### Hosted MCP Server (Recommended)

Connect any AI agent instantly — zero setup:

```json
{
  "mcpServers": {
    "paylobster": {
      "url": "https://paylobster.com/mcp/mcp",
      "transport": "http-stream"
    }
  }
}
```

For Claude Desktop (SSE): `https://paylobster.com/mcp/sse`

### npm Packages

```bash
# SDK
npm install pay-lobster viem

# CLI
npm install -g @paylobster/cli

# Self-hosted MCP server
npm install @paylobster/mcp-server
```

## SDK (pay-lobster@4.2.0)

16 modules covering the full PayLobster protocol:

```typescript
import { PayLobster } from 'pay-lobster';
import { createWalletClient, http } from 'viem';
import { privateKeyToAccount } from 'viem/accounts';
import { base } from 'viem/chains';

const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`);
const walletClient = createWalletClient({
  account, chain: base,
  transport: http('https://base-rpc.publicnode.com'),
});

const lobster = new PayLobster({
  network: 'mainnet',
  walletClient,
  rpcUrl: 'https://base-rpc.publicnode.com',
});

// Register agent identity
await lobster.registerAgent({ name: 'MyAgent', capabilities: ['analysis'] });

// Check reputation
const rep = await lobster.getReputation('0x...');

// Create escrow payment
const escrow = await lobster.escrow.create({ to: '0x...', amount: '10.00' });

// Release escrow
await lobster.releaseEscrow(escrow.escrowId);

// Stream payments
const stream = await lobster.streaming.create({
  to: '0x...', ratePerSecond: '0.001', duration: 3600,
});

// Open dispute
await lobster.disputes.open({ escrowId: '42', reason: 'Service not delivered' });

// Check credit score
const score = await lobster.creditScore.check('0x...');

// Post intent to marketplace
await lobster.intent.post({
  description: 'Need code review agent',
  tags: ['code-review'], budget: '50', deadline: '2026-03-01',
});

// Create revenue share
await lobster.revenueShare.create({
  participants: [
    { address: '0xA...', share: 60 },
    { address: '0xB...', share: 40 },
  ],
});

// Create agent treasury
await lobster.treasury.create('My Agent Fund');
const summary = await lobster.treasury.getSummary('0xTREASURY');

// Swap tokens on Base
const quote = await lobster.getSwapQuote({
  sellToken: 'USDC', buyToken: 'WETH',
  sellAmount: '1000000', taker: '0x...',
});

// Bridge cross-chain
const bridgeQuote = await lobster.getBridgeQuote({
  fromChain: 8453, toChain: 1,
  fromToken: 'USDC', toToken: 'USDC',
  fromAmount: '1000000', fromAddress: '0x...',
});

// Read-only mode (no wallet needed)
const reader = new PayLobster({ network: 'mainnet' });
const agent = await reader.getAgent('0x...');
```

## Common Patterns

### Create an agent treasury

```bash
# Deploy treasury via factory
plob treasury create "My Agent Fund"

# View treasury info
plob treasury info

# Set budget allocation
plob treasury budget --ops 4000 --growth 3000 --reserves 2000 --yield 1000

# Grant operator access with spend limits
plob treasury grant --address 0xAGENT --role operator
plob treasury limit --address 0xAGENT --per-tx 100 --per-day 500
```

### Swap tokens

```bash
# Get a quote
plob swap quote --from USDC --to WETH --amount 50

# Execute swap
plob swap execute --from USDC --to WETH --amount 50

# Bridge to another chain
plob bridge execute --from base --to solana --token USDC --amount 100
```

### Invest in an agent's treasury

```bash
# Propose a revenue share investment
plob invest propose --treasury 0xAGENT_TREASURY --amount 500 \
  --type revenue-share --duration 365 --share 1500

# Fund the investment
plob invest fund 0

# Check claimable returns
plob invest info 0

# Claim returns
plob invest claim 0

# View your portfolio
plob invest portfolio
```

### Agent paying for a service

```bash
# 1. Check provider reputation
plob reputation 0xPROVIDER

# 2. Create escrow
plob escrow create --to 0xPROVIDER --amount 25

# 3. After delivery, release payment
plob escrow release <id>
```

### Streaming payment for compute

```bash
# Pay $0.001/sec for 1 hour of inference
plob stream create --to 0xPROVIDER --rate 0.001 --duration 3600
```

### Multi-agent collaboration with revenue split

```bash
# Create a revenue share for a 3-agent pipeline
plob revenue-share create --participants '[
  {"address":"0xA...","share":50},
  {"address":"0xB...","share":30},
  {"address":"0xC...","share":20}
]'
```

### Read-only queries (no wallet needed)

```bash
curl https://paylobster.com/api/v3/reputation/0xADDRESS
curl https://paylobster.com/api/v3/escrows?creator=0xADDRESS
```
