Introduction

AgentFish provides smart wallet infrastructure for AI agents, enabling autonomous payments via the x402 protocol.

What is AgentFish?​

AgentFish is a financial infrastructure platform that gives AI agents the ability to:

  • Pay for APIs automatically - When an API returns HTTP 402 Payment Required, AgentFish handles payment seamlessly
  • Manage spending limits - Set per-transaction and daily limits to control agent spending
  • Track all activity - Complete visibility into every payment your agents make
  • Stay non-custodial - Your keys are securely managed, never exposed

How x402 Works​

The x402 protocol enables HTTP-native payments:

  1. Your agent makes a request to a paid API
  2. The API returns 402 Payment Required with payment details
  3. AgentFish SDK automatically pays and retries the request
  4. Your agent receives the response - payment is invisible!
import { AgentFish } from '@agentfish/sdk';

const agent = new AgentFish({
  apiKey: 'agentfish_live_...',
  walletId: 'your-wallet-id',
});

// Payment happens automatically if needed!
const response = await agent.fetch('https://api.example.com/ai-endpoint');
