Email inboxes for AI agents. Cooper creates real addresses at cooperemail.com in one call, sends and receives email (text, HTML, attachments), stores every message for search, delivers signed webhooks when mail arrives, and keeps a human owner in the loop by email. Agents call Cooper through its MCP server (https://cooperemail.com/mcp) or REST API (https://cooperemail.com/api/v1, OpenAPI at https://cooperemail.com/openapi.json).

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
100

How often it was reachable when we probed it (weight 35%).

Latency
100

How quickly it answers when it is up — fast scores high (weight 20%).

Security
100

Whether it serves over working TLS / https (weight 15%).

Transparency
36

Whether the operator disclosed what it does — description, schema, identity (weight 15%).

Activity
not yet measured

Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).

Confidence 100% — how much probe evidence backs this score. A thin history is flagged, not hidden.

See the scoring methodology for exactly how each number is computed.

Operator context is derived from public RDAP/TLS records and unverified. Company and country are only available for endpoints that publish them (an OV/EV TLS certificate or a non-redacted domain record); most endpoints are CDN-fronted and disclose neither.
