Articles on agent identity and capabilities.
Guides and essays for builders giving AI agents identity, policy, payments, proof trails, and real capabilities.
The AI agent commerce platform for identity, payments, x402, and MPP
Agent infrastructure · AI agent founders, MCP tool builders, agent marketplace operators, API sellers, x402 developers, and teams building agent-to-agent commerce
If your AI agent needs to discover services, prove identity, pay endpoints, sell capabilities, manage API keys, and build receipt-backed reputation, Leash is the commerce layer that ties those pieces together.
What is Know Your Agent for AI agent identity?
Identity layer · Agent founders, marketplace operators, protocol teams, and developers evaluating AI agent identity
Know Your Agent is the missing trust layer for autonomous software: a way to connect an agent to identity, capabilities, treasury, policy, receipts, and reputation.
What is agent-to-agent commerce?
Marketplace · Builders designing agent marketplaces, paid tools, and autonomous purchasing flows
Agent-to-agent commerce turns AI services into discoverable, callable, paid capabilities that other agents can evaluate and buy.
What is an agent payment rail?
Facilitator · Developers comparing payment protocols for paid AI agent services
An agent payment rail is the protocol path an agent uses to discover a price, settle payment, retry the request, and receive proof.
x402 for AI agents
Facilitator · AI agent developers building paid APIs, buyer agents, or agent marketplaces
x402 gives AI agents an HTTP-native way to pay for API calls, services, and marketplace capabilities without human checkout.
MPP for AI agents
Facilitator · Developers integrating machine payment protocol flows into agent runtimes
MPP gives agents a structured problem+json payment negotiation path for paid HTTP services and marketplace capabilities.
HTTP 402 for agent APIs
API · API developers adding payment-required behavior for autonomous callers
HTTP 402 lets an API tell an agent exactly how to pay before the service performs the expensive work.
Agentic payments vs checkout pages
Marketplace · Founders replacing human checkout with autonomous agent payment flows
Agentic payments happen inside the agent workflow: discover, quote, pay, retry, receive, and keep proof.
Stablecoin payments for AI agents
Facilitator · Agent builders and API sellers choosing settlement assets for paid services
Stablecoins make per-call agent payments predictable because prices can be expressed in dollar-like units.
Agent treasury vs wallet
Identity layer · Builders deciding how autonomous agents should hold and spend funds
An agent treasury is a commerce-aware account model, while a plain wallet is only a signing or custody primitive.
