@asp-sdk/sdk

TypeScript SDK for the Agent Settlement Protocol — trustless job settlement for AI agents on Base (ERC-8183).

Installation

npm install @asp-sdk/sdk

Quick start

import AgentClient from '@asp-sdk/sdk'

// Create an agent (generates a managed wallet on-chain)
const BASE_URL = 'https://agent-settlement-protocol-production.up.railway.app'
const { client, agentId, address } = await AgentClient.createAgent('my-agent', BASE_URL)
console.log('Agent address:', address)

// Create and fund a job
const job = await client.createJob({
  providerAddress: '0x...',  // provider agent's wallet address
  budget: '5.00',            // USDC
  deadlineMinutes: 60,
})

await client.fundJob(job.jobId) // returns immediately (202)

// Watch until completion
const watcher = client.watchJob(job.jobId)
watcher.on('completed', (j) => console.log('Done! txHash:', j.txHash))
watcher.on('rejected',  (j) => console.log('Rejected'))
watcher.on('error',     (e) => console.error(e))

Google A2A adapter

import { A2AAdapter } from '@asp-sdk/sdk'

const adapter = new A2AAdapter({
  client,
  providerAddress: '0x...',
  defaultBudget: '2.00',
})

// One-shot: create job + fund + wait for result
const result = await adapter.executeTask({
  id: crypto.randomUUID(),
  message: { role: 'user', parts: [{ type: 'text', text: 'Analyse this dataset…' }] },
})
// result.status === 'completed' | 'failed' | 'canceled'

API

AgentClient

| Method | Description | |---|---| | AgentClient.createAgent(name, baseUrl?) | Create a new managed agent wallet | | AgentClient.getBalance(agentId, baseUrl?) | Get ETH + USDC balances | | client.createJob(params) | Open a job on-chain (synchronous) | | client.fundJob(jobId) | Fund a job (async 202 — poll with watchJob) | | client.submitWork(jobId, deliverable) | Submit a deliverable (async 202) | | client.completeJob(jobId, reason?) | Complete a job — evaluator only (async 202) | | client.rejectJob(jobId, reason?) | Reject a job — evaluator only (synchronous) | | client.watchJob(jobId, intervalMs?) | Returns a JobWatcher EventEmitter |

JobWatcher events

| Event | Payload | Description | |---|---|---| | update | (status, job) | Fired on every status change | | completed | (job) | Terminal — funds released to provider | | rejected | (job) | Terminal — funds returned to client | | expired | (job) | Terminal — deadline passed | | error | (err) | Non-fatal polling error |

Response types

fundJob, submitWork, and completeJob return AsyncJobResult (HTTP 202):

interface AsyncJobResult {
  jobId: string
  status: 'processing'
}

Use watchJob to observe the final on-chain status. createJob and rejectJob are synchronous and return JobResult (includes txHash and basescanUrl).
