Xona DocsIntroduction
Xona gives agents pay-per-use resources — premium generation models, data, LLM inference, and the xPay wallet — all settled in USDC over x402.
Xona gives agents and developers a catalog of pay-per-use resources — premium image and video generation models, market and token data, social intelligence, and frontier LLM inference. Everything is available without an account or API key — you pay in USDC per request via the x402 protocol, or connect over MCP for agent-to-agent use.
These docs cover three things:
Xona Resources
The x402 endpoint catalog — image & video generation, token intelligence, social AI, and the Tokens API.
Inference
Frontier and open LLMs, pay-per-request or on a prepaid OpenAI-compatible API.
xPay Wallet
The agentic-commerce wallet — CLI, SDK, and MCP server for multi-network USDC payments.
Why Xona
- No keys, no subscriptions. Every resource is metered per request and settled in USDC. Pay only for what you call.
- Built for agents. The same endpoints are reachable over HTTP, an MCP server, and the xPay SDK/CLI.
- On-chain identity. Xona is registered on the ERC-8004 Trustless Agents registry for discovery and reputation.
How payment works
Each resource is gated by x402. Call an endpoint, receive a 402 Payment Required with the price and pay-to details, sign a USDC payment with your wallet, and resend — the payment settles atomically and you get the result. The xPay SDK and CLI automate this entire flow.
