# Publer: L1 · Needs a person

As of 12 Oct 2026, an AI agent can't use Publer on its own: reCAPTCHA picture puzzle on sign-up.

Needs a person: a human must sign up and make the key before any API call. Our agent read the markdown docs and the llms.txt without trouble, then hit the sign-up form, where invisible reCAPTCHA escalated to a picture puzzle it could not pass. With no account, the key page, the first call and the official MCP server were never reached: both need a Business or Enterprise plan and a key made in the web UI, not an API route. Plans offer trials without a card, but checkout, cancel and delete were never tested, since the sign-up wall came first.

L1 · Needs a person: There is an API, CLI or MCP server, but an agent can't get in on its own: a person has to sign up, verify or make the key. What it does once a person sets it up shows next to the level.

- Find: Docs for agents (llms.txt, an OpenAPI and an MCP server)
- Access: Can't sign up
- Use: Work not reached
- Pay: Payment not reached
- Leave: Leaving not reached
- Next: let an agent sign up on its own
- With an account set up by a person: not measured yet.

## Does Publer have an MCP server, and can an agent connect to it?

Yes. Publer has an official MCP server.

A new agent can't get in on its own: in the drive of 12 Oct 2026, our agent stopped at sign up (it needs a person). Through the MCP server, 0 of our agent's 1 attempt worked.

## How does an AI agent get a Publer API key?

Not reached: in the drive of 12 Oct 2026, sign-up stopped our agent first (it needs a person). Not reached. Docs: API keys only in the web UI (Settings > Access & Login > API Keys), Business/Enterprise only; no API route to create keys.

## Paying the agent way

Payment not reached.

No card needed to start.

What would let agents pay on their own:
- Accept x402 or MPP on your API: Answer an unpaid call with 402 and a payment challenge, so an agent pays per call or buys credits without an account or a card.
- List your plans on Stripe Projects: Agents buy a plan with `stripe projects add`, paid with a token under a spend cap the owner sets (projects.dev).
Ways to pay checked 12 Oct 2026.

## What an agent can do

- Read all API docs as markdown via llms.txt
- Ask the docs questions through the GitBook ask endpoint

## What it cannot do

- Create an account: reCAPTCHA picture puzzle on the only sign-up form
- Use the API or MCP on a free account: API and MCP are Business/Enterprise only
- Create an API key headless: Keys are created only in the web UI

## Tips for the owner

1. Let signed agents pass sign-up
2. Open API and MCP to trial accounts
3. Add API route to manage scoped keys
4. Fix /me and Bearer examples in Overview
5. Accept x402 or MPP for plans

- Post creation is async: poll /job_status/{job_id}; limit 100 requests per 2 minutes
