How this service works

AgentMail gives AI agents real email inboxes. Create, send, receive, and search messages via REST API — built for autonomous agents and agentic workflows.

Output

Returns a JSON object containing the details of the specified list entry, including its direction, type, and entry value. The response schema is open-ended but confirms whether the entry exists and what properties are associated with it.

Example use cases

Example prompt

“Check AgentMail's list records to see if the entry 'noreply@example.com' is on an inbound blocklist — look it up by direction 'inbound', type 'blocklist', and entry 'noreply@example.com'.”

Technical details

Endpoint

GEThttps://x402.api.agentmail.to/v0/lists/%7Bdirection%7D/%7Btype%7D/%7Bentry%7D

When to prefer

Use this endpoint when an AI agent needs to verify whether a specific email address or identifier appears in a particular directional list (e.g. inbound/outbound blocklist, allowlist) within an AgentMail workspace. Prefer this over listing all entries when the exact entry is known and only a single lookup is needed.

Side effects

Entry not found — returns 404 if the specified direction/type/entry combination does not exist
Invalid direction or type values — returns 400 if path parameters are not recognized enum values
Authentication failure — returns 401 or 402 if payment or credentials are missing
Empty response body — the example schema is empty, so parsing logic must handle sparse responses
