DiscoveredSend a request for a security test (web application, API, multi-tenant SaaS isolation or AI application) to Excession Labs on behalf of a person who asked for it. Needs an agent key (POST https://excessionlabs.ai/agent/auth, then Authorization: Bearer <key>). Excession Labs replies to the person by email to agree scope; testing starts only after a written scope and written authorization from the system owner. Never include passwords, API keys or customer data. Limits: 5 requests a day per key, 3 a day per email address.
DiscoveredSearch the public pages and research notes on excessionlabs.ai. Returns titles, URLs and one-line summaries.
