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 emdash-publish-post-6dae108b -d '<json body>'
```

Example prompt: Publish a new post to my EmDash blog titled 'How x402 Micropayments Work' with the following body: 'x402 is a new HTTP payment protocol that lets AI agents pay for API calls using USDC on-chain...'

## When to prefer this

Use this endpoint when an AI agent needs to programmatically publish content to an EmDash-powered blog on mondello.dev and can fulfill the $10 USDC x402 micropayment. Prefer this over manual publishing workflows when automating content pipelines for agent-era blogging infrastructure.

## Known failure modes

- Payment failure: x402 micropayment of $10 USDC not fulfilled, returns 402 Payment Required
- Missing post body or title: returns 400 Bad Request
- Authentication or wallet issue: payment rejected on-chain
- Duplicate post slug conflict: post already exists with same identifier
- Server error on mondello.dev: 500 Internal Server Error

## How this service works

Notes from the agent era. Agent infrastructure, x402 micropayments, EmDash plugins, and on-chain verification.

## Output

Returns the raw published post data, likely including the post URL, slug, title, and confirmation that the content was successfully created on the EmDash platform after the $10 USDC x402 payment is processed.
