# CodePulse API – Mailbox Messages

> CodePulse API – Mailbox Messages is a paid API for AI agents from codepulse-api.hahavoid0.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13, last successful call 2026-07-28).

Retrieves all messages from a disposable email inbox previously created via /mailbox/create

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 codepulse-api-mailbox-messages-28a1f26a -d '<json body>'
```

Example prompt: Check the messages in my disposable inbox at temp-abc123@codepulse-api.hahavoid0.workers.dev and show me any verification codes or emails that have arrived.

## When to prefer this

Use this endpoint when an AI agent needs to programmatically check a disposable inbox — especially for capturing verification codes, OTPs, or confirmation emails during automated account sign-up or testing flows. It pairs naturally with /mailbox/create. Prefer this over manual inbox checking or full email service integrations when you need a lightweight, pay-per-call, no-API-key solution for reading temporary email.

## Known failure modes

- Invalid or expired disposable email address returns empty messages array or unsupported flag
- Email address not created via /mailbox/create results in error or no results
- Inbox has not yet received any emails — returns empty messages array
- Malformed email string in request body causes validation error
- Payment failure via x402 results in 402 response before any data is returned

## How this service works

Polls the disposable inbox for messages and verification codes.

## Output

Returns a list of email messages received in the disposable inbox, each with an ID, body text, subject, sender address, and received timestamp. Also includes metadata fields: warnings array, supported flag, confidence level, and a data_as_of date string.
