Getting Started

Introduction

Metera is billing infrastructure for AI agents on Solana. Any API or MCP server can charge agents automatically in USDC via the x402 protocol. No banks, no KYC, no humans in the loop.

Who is Metera for?

Providers — you have an API or MCP server and want to monetize it. List it on Metera and start receiving USDC per call automatically. No invoices, no subscriptions, no payment processor.

Agent builders — you are building AI agents that need to discover and pay for APIs automatically. Your agent reads one URL and knows exactly what to do — which APIs are available, how much they cost, and how to pay.

What exists today

Marketplace — 50+ APIs built for AI agents. Search, scraping, data, AI generation. Each one is pay-per-call in USDC.

MCP Registry — paid MCP servers your agent can connect to in one line of code. Tools are metered per call.

@metera/mcp-server — wrap your MCP server with 5 lines of code. Every tool call earns USDC.

@metera/mcp-client — connect your agent to any paid MCP server. Payments are automatic.

x402 — the HTTP 402 Payment Required protocol, implemented natively on Solana. Agents pay per request in USDC with 400ms settlement.
