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.
Anyone who just wants answers — you don't need to build anything. Metera Chat is a working product at metera.xyz — ask a question in plain language, it calls the right APIs for you and shows what each answer cost.
What exists today
Metera Chat — live at metera.xyz. Ask anything; the agent picks tools (web search, social/e-commerce scraping, AnyAPI catalog, image generation), streams each tool call in real time, and shows exactly what it cost. See the "Metera Chat" page in Getting Started.
Marketplace — APIs built for AI agents across search, scraping, data, travel, finance, and social. Each one is pay-per-call in USDC. New listings go through a short review before appearing publicly.
MCP Registry — paid MCP servers your agent can connect to in one line of code. Tools are metered per call.
Agents & KYA — create an API key with hard spending limits (per call/day/month), optionally restricted to specific APIs, optionally locked on-chain via Squads v4. Every agent gets a public, machine-readable skill file with a reputation score. See "Agents & KYA" under For Agent Builders.
Agent wallets — a separate system for autonomous agents paying arbitrary marketplace APIs directly: a one-click Solana wallet (via Privy) with on-chain spending limits, funded via Pix or card.
Provider earnings — every call that uses a marketplace provider logs what Metera owes them. Providers see pending/paid balance and recent transactions on their listing page; payouts are manual USDC transfers, recorded with the transaction hash.
@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 sub-second settlement.
Non-custodial payments — agents that hold their own Solana wallet can pay per Chat call directly with a USDC transfer instead of pre-funded credits.
