# PayWeave Mail – List Inbox Messages

> PayWeave Mail – List Inbox Messages is a paid API for AI agents from mail.payweave.services, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Retrieves a paginated list of messages in a disposable email inbox identified by a slug, returning metadata like sender, subject, timestamp, and message size.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability payweave-mail-list-inbox-messages-d303031c
```

Example prompt: Check the PayWeave Mail inbox called 'agent-verify-42' and list all the messages that have arrived — I need to see what emails came in, including who sent them and their subjects.

## When to prefer this

Use this endpoint when an AI agent needs to poll or check a disposable/temporary email inbox for incoming messages — especially in automated workflows where an agent creates a throwaway email address, triggers a signup or verification flow elsewhere, and then needs to list received emails to extract a confirmation link or code. Prefer this over persistent email providers when privacy, disposability, and pay-per-use micropayment pricing are priorities.

## Known failure modes

- Unknown or expired inbox slug returns 404 not found
- Missing or invalid x402 payment header returns 402 payment required
- Rate limit exceeded returns 429
- Malformed slug format returns 400 bad request
- Empty inbox returns 200 with empty messages array and null cursor

## How this service works

Disposable email inboxes for agents — create, receive, read, and send. Pay per call.

## Output

Returns a JSON object with a 'messages' array (each item containing id, from, subject, received_at, and size fields) and a nullable 'cursor' string for paginating through additional messages.
