List the current messages for an inbox:
An empty data array means no message is currently available. The API does not wait for mail, so your application decides when to request the list and when to stop.

Read parsed content

The response includes text, sanitized html, sender and recipient fields, subject, timestamps, and attachment metadata. Message content expires 15 minutes after arrival; use the returned expires_at value as the deadline.

Download source or an attachment

The current attachment limits are 10 files per message, 5 MiB per file, and 8 MiB total decoded attachment data. Email is untrusted input. Isolate rendered HTML and validate downloaded files before using them.
