## 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 scrapemole-social-mastodon-hashtag-timeline-9a1c0e5e
```

Example prompt: Pull the 30 most recent public Mastodon posts tagged #climatechange from the mastodon.social instance so I can see what people are discussing right now.

## When to prefer this

Choose this endpoint when you need real-time public posts from the Mastodon/fediverse ecosystem filtered by hashtag, without setting up OAuth or managing accounts. It is ideal for monitoring fediverse discourse, trend detection, or data collection pipelines that need pay-per-call pricing with no subscription. Prefer it over manual API wiring when you need quick, instance-aware hashtag timelines across different Mastodon servers.

## Known failure modes

- Invalid or non-existent hashtag returns empty posts array
- Unknown or unreachable Mastodon instance causes timeout or error
- limit out of range (must be 1-40) returns validation error
- Payment failure via x402 results in no charge and no response
- Rate limits on the upstream Mastodon instance may throttle results

## How this service works

Pay-per-call public social data for agents: Telegram public channel posts; Mastodon hashtag timelines; Bluesky post search, profiles and author feeds; Hacker News full-text search and threads with comments; Lobsters hottest stories. Official public APIs only, no logins, no private data. USDC via x402, no accounts; failed calls are never charged.

Payments: x402 v2, scheme "exact", USDC on Base (eip155:8453). The payment is verified before the work and settled only when the response is 200. Terms: https://social.scrapemole.workers.dev/terms
