How this service works
Curated Bitcoin coinbase scriptSig messages (printable ASCII only). Pool tags, BIP-comment campaigns, political statements. Window up to 7d.
Output
A curated list of printable ASCII coinbase scriptSig messages from Bitcoin blocks within the requested time window (up to 7 days), categorized by type: mining pool tags, BIP comment/campaign messages, and political statements. Each entry includes the message text and associated block metadata, parsed from the provider's own Bitcoin full node.
Example use cases
Example prompt

Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/btc-derivatives/coinbase-messagesWhen to prefer
Choose this endpoint when you need human-readable, curated coinbase scriptSig messages specifically (pool tags, BIP campaigns, political statements) sourced from a dedicated full-node parser with printable-ASCII filtering. Prefer it over raw blockchain explorers when you want pre-filtered, research-ready message data without having to parse raw binary scriptSig fields yourself.
Side effects
- Window exceeds 7-day maximum — returns error or truncated result
- No messages found in the requested window — returns empty list
- Node sync lag may cause very recent blocks to be missing
- Non-printable ASCII messages are filtered out and will not appear
- Rate limiting or payment failure via x402 protocol
