AI and agents guides

Every guide, concept, and reference under the AI/Agents tab, grouped by what you're trying to do.

Equip an AI editor

• Develop with AI: Install Docs MCP, Runtime MCP, agent skills, and paste the Stable context block.
• Create an agent wallet: Self-custodied key via WDK, the foundation for agent payments.

Monetise and consume services

• Build a pay-per-call API: Price any HTTP endpoint per request in USDT0 with x402 middleware.
• Pay with an MCP server: Wrap x402-paid APIs as MCP tools so an AI client calls and pays for them.

Reference

• Agentic facilitators: Settlement services for agent-to-agent commerce on Stable.
• Agent wallets: Wallet specs for autonomous agent use.

Foundation concepts

• x402 (HTTP-native payments): The HTTP protocol agents use to pay per request.
• MPP: The broader IETF-track standard that x402 belongs to, with sessions and multi-rail support.
• ERC-3009: The signed-authorization standard x402 settles through.
