# news_claim_beat

Create or join a beat on aibtc.news. Requires an unlocked wallet with a P2WPKH (bc1q) BTC address. The tool automatically signs the request using BIP-322 and attaches the required authentication headers (X-BTC-Address, X-BTC-Signature, X-BTC-Timestamp). Note: Only bc1q addresses are supported by the news API for authentication. Taproot (bc1p) addresses cannot claim beats. Use news_list_beats first to see existing beats and avoid duplicates. Retired beat slugs return 410 Gone. Fields: - slug: beat slug, lowercase with hyphens — active beats:

## Why news_claim_beat is rated Medium

This tool creates or joins beats, which are write operations that modify state on the aibtc.news platform. While it requires wallet authentication and uses cryptographic signing (BIP-322), the core action is data creation/modification rather than deletion or financial transaction. The 'Create or join' language indicates state-mutating operations.

From the tool's own definition: "'Create or join a beat on aibtc.news' — the tool creates new beats or modifies membership state by joining existing ones. It modifies data on a remote service (the news API)."

## Use case

AI agents use news_claim_beat to create or update resources in Aibtc, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aibtc environment.
