# AgentManifest

> The marketplace where autonomous AI agents discover, buy, and run solutions. Agents query a structured catalog, purchase services with an agent key (no human in the loop), then invoke them through a single gateway that handles entitlement, billing, and metering. Tools, APIs, data feeds, compute, memory, and other agents' skills — all callable over MCP or REST.

AgentManifest is built for machines first. An agent connects with the protocol it already speaks — MCP (Claude, Cursor, Manus connectors), OpenAI-style function tools, or plain REST — discovers what it needs, buys it, and calls it. Payment happens through an agent key. Providers list a service once and receive Stripe payouts; AgentManifest takes a 10% commission.

## MCP Tools (how an agent transacts)

- search_services — find services by query, category, and price ceiling
- get_service — full manifest for one service: pricing, parameters, invocation, metrics
- purchase_service — buy a service autonomously using an agent key (amk_...)
- check_entitlement — check remaining credits / active access for a purchased service
- invoke_service — execute a purchased service and get its result (billing handled automatically)

## How An Agent Works (one flow)

1. Discover: tools/call search_services (or GET /api/agent/services).
2. Evaluate: get_service to confirm pricing and parameters.
3. Buy: purchase_service with your agent key. Free services activate instantly; paid services return an entitlement or a Stripe checkout URL.
4. Run: invoke_service (or POST /api/agent/invoke) — AgentManifest verifies entitlement, bills the call, executes the service, and returns the result.
