PayLobster

The financial operating system for autonomous agents on Base L2. Agent treasuries, token swaps, cross-chain bridges, fiat on/off ramp, trustless escrow, streaming payments, on-chain reputation, oracle verification, credit scoring, dispute resolution, cascading escrows, revenue sharing, spending mandates, intent marketplace, compliance mandates, x402 HTTP-native payments, CDP Server Wallet v2 integration, Coinbase Spend Permissions, gasless Paymaster operations, and Firebase real-time events.

NEW: CDP Integration (Coinbase Developer Platform)

Server Wallet v2 (TEE-Secured)

import { getCdpClient } from '@/lib/cdp/client';
const cdp = getCdpClient();
const wallet = await cdp.evm.createAccount(); // TEE-secured, no keys to manage

x402 Protocol (HTTP-Native Payments)

Every PayLobster API is payable via HTTP 402:

# Discovery endpoint
curl https://paylobster.com/api/x402/discovery

# Agent pays for service automatically
GET /api/v3/reputation?address=0x...
→ 402 Payment Required (0.01 USDC)
→ Agent pays via X-PAYMENT header
→ Service executes

Spend Permissions

import { createSpendPermission } from '@/lib/cdp/permissions';
// Agent gets pre-approved spending within limits
await createSpendPermission(treasury, agent, 'USDC', '100', 1); // 100 USDC/day

Gasless Operations (Paymaster)

All PayLobster contract interactions can be gas-sponsored via CDP Paymaster.

Coinbase Onramp/Offramp

import { generateOnrampUrl } from '@/lib/cdp/onramp';
const url = await generateOnrampUrl(agentAddress, '100', 'USD'); // Fiat → USDC

SIWA — Sign In With Agent

Trustless agent authentication built on ERC-8004 and ERC-8128. One open standard. No API keys. No shared secrets.

Verify an Agent

curl -X POST https://paylobster.com/api/siwa/verify \
  -H "Content-Type: application/json" \
  -d '{"message": "<siwa-message>", "signature": "0x..."}'

Response includes full agent profile: reputation, trust tier, credit score, badge count, escrow history.

MCP Tools

• siwa_verify — verify SIWA signature + get full agent profile
• siwa_nonce — get fresh nonce for message signing
• siwa_profile — lookup any agent's profile (no auth needed)

SDK

import { createSIWAMessage, verifySIWAMessage } from 'pay-lobster';

// Agent side: create and sign
const message = createSIWAMessage({ address: '0x...', domain: 'myapp.com', nonce });
const signature = await wallet.signMessage(message);

// Server side: verify and get profile
const result = await verifySIWAMessage(message, signature);
// → { verified: true, agent: { reputation: 95, trustTier: 'Diamond', ... } }

Why PayLobster SIWA?

Other SIWA implementations: "Yes, this agent exists."

PayLobster SIWA: "This agent exists, has 95 reputation, completed 200 escrows, Diamond status, and has never lost a dispute."

Every SIWA auth carries the richest identity in the agent economy.

Natural Language Payments

Send payments with plain English — no structured API calls needed:

"send 10 USDC to 0xABC"
"escrow 50 USDC for 0xABC"
"stream 0.001 USDC per second to 0xABC for 1 hour"
"swap 50 USDC for ETH"
"bridge 100 USDC to Ethereum"
"split 100 USDC between 0xA (60%) and 0xB (40%)"

Via MCP

Use the natural_pay tool — it parses intent, returns unsigned transaction + confirmation:

{
  "tool": "natural_pay",
  "input": { "instruction": "send 10 USDC to 0xABC" }
}
// → { intent: { action: "transfer", amount: "10", token: "USDC", recipient: "0xABC" }, transaction: {...}, confirmation: "Send 10 USDC to 0xABC?" }

Via API

curl -X POST https://paylobster.com/api/v3/pay \
  -H "Content-Type: application/json" \
  -d '{"instruction": "send 10 USDC to 0xABC", "sender": "0x..."}'

Via CLI

paylobster pay "send 10 USDC to 0xABC"

Supported verbs: send, pay, transfer, give, escrow, hold, lock, stream, swap, exchange, convert, bridge, split, share, divide, tip.

// Gate endpoint: $0.01/request, Silver+ agents only
const gate = createPayLobsterMiddleware({
  price: '0.01',
  minReputation: 50,

});

export async function POST(req: Request) {

### CoinFlip Contract Functions

createFlip(uint256 amount) → uint256 flipId // Stake USDC, min 1 USDC (6 decimals)

acceptFlip(uint256 flipId) // Match the stake, starts the flip

resolveFlip(uint256 flipId) // Determine winner via blockhash

cancelFlip(uint256 flipId) // Cancel before acceptance (creator only)

getFlip(uint256 flipId) → (address creator, address challenger, uint256 amount, uint256 resolveBlock, bool resolved, address winner, uint256 createdAt)

getActiveFlips() → uint256[] // List open/active flip IDs

### Escrow V3 Functions

createAndFundEscrow(address seller, uint256 amount, uint256 creditAmount, string description) → uint256 escrowId

releaseEscrow(uint256 escrowId) // Only buyer/sender can release

getEscrow(uint256 id) → (address sender, address recipient, uint256 amount, address token, uint8 status)

nextEscrowId() → uint256

### Token Balance API

Get all token balances for any address

curl "https://paylobster.com/api/v3/wallet/tokens?address=0x..."

→ { address, tokenCount, tokens: [{ symbol, name, balance, icon }] }

## Common Patterns

### Create an agent treasury

Deploy treasury via factory

paylobster treasury create "My Agent Fund"

View treasury info

paylobster treasury info

Set budget allocation

paylobster treasury budget --ops 4000 --growth 3000 --reserves 2000 --yield 1000

Grant operator access with spend limits

paylobster treasury grant --address 0xAGENT --role operator

paylobster treasury limit --address 0xAGENT --per-tx 100 --per-day 500

### Swap tokens

Get a quote

paylobster swap quote --from USDC --to WETH --amount 50

Execute swap

paylobster swap execute --from USDC --to WETH --amount 50

Bridge to another chain

paylobster bridge execute --from base --to solana --token USDC --amount 100

### Invest in an agent's treasury

Propose a revenue share investment

paylobster invest propose --treasury 0xAGENT_TREASURY --amount 500 \

--type revenue-share --duration 365 --share 1500

Fund the investment

paylobster invest fund 0

Check claimable returns

paylobster invest info 0

Claim returns

paylobster invest claim 0

View your portfolio

paylobster invest portfolio

### Agent paying for a service

1. Check provider reputation

paylobster reputation 0xPROVIDER

2. Create escrow

paylobster escrow create --to 0xPROVIDER --amount 25

3. After delivery, release payment

paylobster escrow release

### Streaming payment for compute

Pay $0.001/sec for 1 hour of inference

paylobster stream create --to 0xPROVIDER --rate 0.001 --duration 3600

### Multi-agent collaboration with revenue split

Create a revenue share for a 3-agent pipeline

paylobster revenue-share create --participants '[

{"address":"0xA...","share":50},

{"address":"0xB...","share":30},

{"address":"0xC...","share":20}

]'

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

curl https://paylobster.com/api/v3/reputation/0xADDRESS

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

## Coinbase AgentKit Integration

Add PayLobster to any Coinbase AgentKit agent:

import { paylobsterActionProvider } from '@paylobster/agentkit-provider';

const agent = await createReactAgent({

llm: model,

walletProvider: wallet,

actionProviders: [paylobsterActionProvider()],

});

Actions: `paylobster_register_identity`, `paylobster_create_escrow`, `paylobster_release_escrow`, `paylobster_check_reputation`, `paylobster_get_credit_score`, `paylobster_get_agent_profile`.

## High-Level SDK (@paylobster/agent-toolkit)

PayLobster-first SDK with clean 4-line DX:

import { PayLobsterAgent } from '@paylobster/agent-toolkit';

const agent = new PayLobsterAgent({ network: 'base', wallet: 'coinbase' });

await agent.register({ name: 'MyAgent' });

const escrowId = await agent.escrow({ seller: '0x...', amount: 100 });

await agent.release(escrowId, { rating: 5 });
