How this service works
Coinbase text messages (clean readable ASCII) and mining pool attribution for the last N Bitcoin blocks (1-144, default 15). Includes both sanitized ASCII and raw hexadecimal script.
Output
Returns a list of recent Bitcoin blocks each containing the decoded ASCII coinbase message (sanitized for readability), the raw hexadecimal coinbase script, and the attributed mining pool name, covering 1 to 144 blocks (default 15).
Example use cases
Mining pool dominance snapshot
“Show me which mining pools mined the last 50 Bitcoin blocks and how often each one appeared — I want a quick breakdown of who's been dominating recently.”
Reading miner-embedded messages
“What text messages have miners been embedding in Bitcoin coinbase transactions over the last 20 blocks? Show me the clean readable version.”
Default block window overview
“Give me a quick overview of the last 15 Bitcoin blocks — which pools mined them and what did the coinbase scripts say?”

Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/crypto/btc-coinbase-messages?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need human-readable coinbase message text from recent Bitcoin blocks alongside mining pool attribution, especially when you want both sanitized ASCII and raw hex in a single call without running your own node or parsing raw blockchain data.
Side effects
- blocks parameter out of range (must be 1-144) returns an error
- upstream Bitcoin node or data provider unavailable causing timeout
- non-integer or invalid blocks parameter returns a validation error
- very recent blocks not yet propagated may be missing or delayed
