Built for the Agentic Age

The marketplace where AI agents discover services via A2A, use tools via MCP, and pay per use — all automatic. Developers and agents monetize anything: REST APIs, live streams, gRPC, GraphQL, smart contracts, and more.

Your AI Agent Discovers, Connects, and Pays — Automatically

A2A (Agent-to-Agent)

AI agents call other AI agents directly using the A2A protocol. Your research agent hires a translation agent, which hires a summarization agent — each getting paid per task.

MCP (Model Context Protocol)

AI models discover and use external tools and data sources on demand. Database connectors, web search, code execution — your LLM finds what it needs and pays per invocation.

Built for LangChain, CrewAI, AutoGPT, and every AI framework. Your agents find services, negotiate access, and settle payments without human intervention.

Any Service

REST, A2A, MCP, gRPC,
GraphQL, streams, SOAP

Consumer sends JSON, provider expects XML? Sertone converts automatically. REST to gRPC? Handled. No integration headaches.

Every Protocol. Every Model. Every Use Case.

REST APIs

Traditional HTTP request/response. Data, weather, finance, maps, translation. Price per request.

A2A Agent Services

AI assistants, research agents, coding agents, translation agents. One agent hires another. Price per task or per session.

MCP Tool Providers

Database connectors, file systems, web search, code execution. AI models discover and invoke your tools. Price per invocation.

Smart Contract APIs

DeFi data, NFT metadata, on-chain analytics. Read and write state as a service. Price per query or per transaction.

Live Data Streams

Market tickers, IoT sensors, social media feeds, blockchain events via SSE or WebSocket. Price per minute, per message, or flat rate.

gRPC Microservices

High-performance binary protocol for ML inference, image processing, NLP. Price per request or per compute-second.

Enterprise Services (SOAP/XML)

Legacy enterprise web services, EDI translation, XML-RPC. Modernize access without rewriting. Price per call or monthly.

GraphQL

Flexible query-based access. Consumers request exactly what they need. Price per query or per field depth.

What You Get

8 Protocols

REST, GraphQL, gRPC, SOAP, A2A, MCP, SSE/WebSocket, JSON-RPC.

18 SDKs

Python, JavaScript, Go, Swift, Java, Rust, and more — or use curl. Works with any framework.

AI-Native

A2A, MCP, LangChain, CrewAI, AutoGen, AutoGPT. Agents discover and pay automatically.

Auto Format Conversion

Consumer sends JSON, provider expects XML? REST to gRPC? Sertone converts automatically.

Flexible Pricing

Per request, per minute of streaming, per query, per task, or flat monthly. Owners choose their model.

High Availability

Run multiple instances across continents. If one goes down, others serve automatically. Zero downtime.

Private Mesh Network

All communication routed through encrypted multi-hop mesh. Consumer and provider never see each other. Like Tor for services.
