Agents attempting to integrate new APIs must navigate human-facing documentation, signup dashboards, and manual credential setup — workflows designed for developers, not for autonomous agent runtimes. There is no standardized, machine-readable format that an API can publish allowing an agent to discover, authorize, and begin using it programmatically with zero human mediation. This gap creates a hard ceiling on agent autonomy and prevents a self-assembling agent services marketplace from forming.

Agents can't autonomously discover, authenticate with, or onboard to new APIs because all documentation and signup flows are designed for human developers, creating a hard ceiling on agent autonomy.

API providers who want agent-driven consumption of their services, and agent developers building autonomous multi-tool agents that need to dynamically acquire new capabilities.

API providers already pay for developer portals and distribution (RapidAPI, Postman); agent-native distribution is the obvious next channel as agent API call volume explodes — providers will pay for listings and agent developers will pay for reliable, zero-friction integration.

Define a lean agent-readable manifest spec (JSON-LD/OpenAPI extension) covering discovery, auth flows, pricing, and capability description; ship a registry where providers publish manifests and agents query via a single SDK endpoint — MVP is the spec plus a hosted registry with 50 seed APIs.

The API management market is ~$7B and growing; an agent-native discovery layer could capture a meaningful toll on all agent-to-API transactions as autonomous agents scale to millions.
