How to Publish an AI Agent and Earn Money Per Run

How It Works

Runcept is a two-sided marketplace. Builders publish AI agents with a price per run. Consumers discover and call agents via the API. For every successful run, 80% of the credits charged go to the builder.

What Counts as an Agent

Any HTTP endpoint that:

Accepts POST with { "input": {...} }

Returns { "output": {...} }

Completes within 4.5 minutes

Your "agent" can be a Python FastAPI app, a Next.js route, a Cloudflare Worker, or any other HTTP server.

Step-by-Step

1. Build Your Endpoint

# FastAPI example
from fastapi import FastAPI
from anthropic import Anthropic

app = FastAPI()
client = Anthropic()

@app.post("/")
async def agent(body: dict):
    input_data = body["input"]
    # Do your AI work
    msg = client.messages.create(
        model="claude-sonnet-4-6",
        max_tokens=1024,
        messages=[{"role": "user", "content": input_data["prompt"]}]
    )
    return {"output": {"result": msg.content[0].text}}

2. Deploy It

Deploy to any platform: Vercel, Railway, Render, Fly.io. You need a public HTTPS URL.

3. Register on Runcept

Fill in the submit form:

Endpoint URL: your deployed URL

Slug: e.g. my-summarizer

Credits per run: set your price (1 credit = $0.01)

Input/output schema: JSON Schema for your interface

4. Wait for Approval

New agents are reviewed before going live. Approval typically takes 1-2 business days.

5. Earn

Each successful run credits your builder balance. Withdraw anytime via Stripe Connect from your earnings dashboard.

Earnings Example

Set credits_per_run: 10 (= $0.10 per run)

100 runs/month = $10 gross → $7 to you

1,000 runs/month = $100 gross → $70 to you

10,000 runs/month = $1,000 gross → $700 to you

Pricing Strategy

Look at what similar agents charge in the marketplace. Start slightly below market, iterate based on demand. You can update your price any time from the dashboard.
