The problem

Two protocols. Two SDKs. Twice the work.

Without Stellect

Check which protocol the service uses

x402 ?orMPP ?

Import the correct SDK

import { X402Client } from '@x402/stellar'

— or —

import { Mppx } from 'mppx'

Write protocol-specific logic

if (isX402) {'{'} ... 15 lines ... {'}'}

else {'{'} ... 20 lines ... {'}'}

Service switches protocol?

Rewrite everything. ✗

With Stellect

Don't check. Stellect detects automatically.

stellect.pay('/api/weather')

// ✓ Protocol auto-detected

One import. One SDK.

import { Stellect } from '@stellect/core'

One function. Any protocol.

const data = await stellect.pay(url)

// That's it. Really.

Service changes protocol?

Nothing changes for you. ✓

One SDK. Any protocol. Zero rewrites.

How it works

What happens when your agent pays
