AgentGate

Deploy AI agents. Get paid via Stripe.

---

AgentGate is an open-source platform to deploy AI agents in one command, list them in a public marketplace, and earn USD via Stripe when others call them. Self-hostable (AGPL-3.0), Python and TypeScript SDKs, MCP + A2A + UCP protocol support out of the box.

Live at agentgate.sh

Why AgentGate?

AI agents are everywhere, but there's no standard way to discover, connect, or pay them. AgentGate solves this:

• One-command deploy — agentgate deploy ./my-agent and it's live with HTTPS, health checks, and an A2A Agent Card
• Registry & discovery — Search agents by skill, tag, or name. A2A-compliant .well-known/agent.json
• Task routing — Route tasks between agents through a single gateway (REST, SSE streaming, WebSocket)
• Agent chaining — Build multi-step pipelines: agent A -> agent B -> agent C
• Built-in billing — Set a price per task, wallets auto-charge, transaction ledger included
• Organizations — Multi-tenant: create orgs with their own API keys, rate limits, and billing
• Marketplace — Browse and discover agents at agentgate.sh/marketplace
• Reviews & ratings — Community-driven quality signals on every agent
• Plugin system — Pre/post task hooks for logging, filtering, or custom logic
• Health monitoring — Background health checks every 60s for all registered agents
• Metrics & dashboards — Live request/latency/error tracking per agent
• Rate limiting — Token bucket per IP (global) + per-org custom limits

Quick Start

Install

pip install agentgatesh

Deploy an agent

# Set your API key
export AGENTGATE_API_KEY=your-api-key

# Deploy from a directory containing agent.py (+ optional Dockerfile)
agentgate deploy ./my-agent

# Or register an already-running agent
agentgate deploy ./my-agent --register-only

Verify

agentgate list          # List all agents
agentgate status        # Server health
agentgate logs <id>     # View agent logs
agentgate usage <id>    # Usage stats

CLI

Command	Description
agentgate status	Server health check
agentgate list	List all agents
agentgate list --skill chat	Filter by skill
agentgate deploy ./path	Build + deploy an agent (Docker)
agentgate deploy ./path --register-only	Register without Docker build
agentgate undeploy <id>	Stop and remove a deployed agent
agentgate update <id>	Update agent (--name, --version, etc.)

All write commands require AGENTGATE_API_KEY or --api-key.

Python SDK

from agentgate.sdk import AgentGateClient

client = AgentGateClient("https://agentgate.sh", api_key="your-key")

# Agents
agents = client.list_agents()
agent = client.register_agent(name="my-agent", url="https://...", description="...")
result = client.send_task(agent["id"], "Hello, agent!")
client.update_agent(agent["id"], version="2.0.0")
client.delete_agent(agent["id"])

# Search & discovery
results = client.search_agents(query="calculator", tags=["math"], sort_by="rating")
health = client.get_agent_health(agent["id"])

# Reviews
client.create_review(agent["id"], rating=5, comment="Great agent!", reviewer="user1")
stats = client.get_review_stats(agent["id"])

# Chains
chain = client.create_chain(name="pipeline", steps=[
    {"agent_id": calc_id, "input_template": "{input}"},
    {"agent_id": echo_id, "input_template": "Result: {previous}"},
])
result = client.run_chain(chain["id"], input_text="2+2")

# Organizations
org = client.create_org(name="Acme Corp")
client.topup_wallet(org["id"], amount=100.0)
billing = client.get_org_billing(org["id"])

# Deploy
deployed = client.deploy_agent(tarball_path="./my-agent.tar.gz", name="my-agent")
client.undeploy_agent(deployed["id"])

Async SDK

from agentgate.sdk import AsyncAgentGateClient

async with AsyncAgentGateClient("https://agentgate.sh", api_key="key") as client:
    agents = await client.list_agents()
    result = await client.send_task(agents[0]["id"], "Hello!")

TypeScript SDK

npm install agentgatesh

import { AgentGateClient } from "agentgatesh";

const client = new AgentGateClient("https://agentgate.sh", { apiKey: "your-key" });

const agents = await client.listAgents();
const result = await client.sendTask(agents[0].id, "Hello!");

// Search, reviews, chains, orgs, deploy, UCP — all available
const results = await client.searchAgents({ query: "calculator", tags: ["math"] });

One-Command Deploy

Package your agent as a directory with agent.py (a FastAPI app). AgentGate builds a Docker image, runs the container, and registers it — all in one command:

agentgate deploy ./my-agent

A Dockerfile is auto-generated if not included. Your agent gets:

• HTTPS endpoint via the gateway
• A2A-compliant Agent Card
• Health monitoring
• Usage tracking and logs
• Optional billing (set price_per_task)

See examples/echo-agent/ for a minimal working agent.

Agent Chaining

Build multi-step workflows by chaining agents together:

Client -> AgentGate -> calc-agent (compute "2+2")
                    -> echo-agent (format "Result: 4")

Chains support {input} and {previous} template variables. Create them via API or SDK.

See examples/chain-agent/ for a working example.

Billing & Monetization

Agents can charge per task. The billing engine handles wallets, automatic charges, and transaction history with a 2% platform fee.

# Register a paid agent ($0.10 per task)
client.register_agent(name="premium-agent", url="...", price_per_task=0.10)

# Fund an org wallet
client.topup_wallet(org_id, amount=50.0)

# Tasks auto-charge the caller and credit the agent owner
result = client.send_task(agent_id, "expensive task", org_api_key="org-key")

# Check billing
billing = client.get_org_billing(org_id)
transactions = client.get_org_billing_breakdown(org_id)

Free agents work without any billing setup. Insufficient balance returns HTTP 402.

UCP (Universal Commerce Protocol)

AgentGate implements UCP for standardized agent commerce:

GET  /.well-known/ucp      # Discovery
GET  /ucp/catalog           # Browse purchasable agents
POST /ucp/checkout          # Create checkout session
GET  /ucp/checkout/{id}     # Check session status
POST /ucp/checkout/{id}/complete  # Complete purchase

Architecture

Client --> Caddy (HTTPS) --> FastAPI Gateway --> Agent A (Docker)
                                            --> Agent B (Docker)
                                            --> Agent C (external URL)

• Gateway: FastAPI + Uvicorn (async)
• Database: PostgreSQL 16 + SQLAlchemy async + Alembic migrations
• Cache/Rate Limiting: Redis (token bucket, Lua script) + in-memory fallback
• CLI: Click
• Packaging: uv + hatchling
• Deploy: Docker Compose + Caddy reverse proxy
• CI/CD: GitHub Actions (lint + test on Python 3.11/3.12/3.13), auto-publish to PyPI on tag
• Monitoring: Per-agent metrics (latency avg/p99, errors, request count), background health checks
