Sigil: Auth and payments for agents
Scoped credentials with built-in permissions, budgets, and expiration. Delegate them to sub-agents. Revoke them instantly. Built on HTTP 402, not a proprietary platform.

API keys are identity theft
Your agent uses a key created by a human, scoped by a human, with no concept of the software entity wielding it. The agent isn't authenticated; the developer is, by proxy.
OAuth assumes a browser
The entire OAuth flow is designed around redirects, login screens, and consent dialogs. Autonomous agents have no browser and no human clicking "Allow."
Delegation doesn't exist
When an orchestrator spawns a sub-agent, it can't create a scoped child credential on the fly. You either share the same key or build custom infrastructure.
