## 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 vextorium-mastodon-followers-751b2c0c -d '<json body>'
```

Example prompt: Can you pull the top 50 followers of Gargron@mastodon.social and tell me which ones are bots and how many followers each of them has?

## When to prefer this

Use this endpoint when you need structured follower data for a specific Mastodon/fediverse account — including bot detection signals and follower counts per follower — without setting up your own Mastodon API credentials. Prefer it over direct Mastodon API access when you want a simple POST interface with per-call micropayment pricing and no OAuth setup.

## Known failure modes

- Account not found or misspelled handle returns an error or empty result
- Private/locked Mastodon accounts may not expose follower lists via the public API
- Instance-level rate limiting or federation issues may cause incomplete results
- Invalid account format (missing @ or instance) causes a validation error
- Limit parameter exceeding API or instance caps may be silently capped or return an error
