How this service works
chainquery Bitcoin RPC: pay-per-call Bitcoin Core over x402, no API key. Active ZMQ notification endpoints from chainquery's independent full node. Bitcoin Core getzmqnotifications.
Output
An array of ZMQ notification objects, each containing the notification type (e.g. 'pubrawblock', 'pubrawtx'), the ZMQ address (e.g. 'tcp://0.0.0.0:28332'), and the configured high-water mark. This tells you what ZeroMQ topics the Bitcoin Core node is actively broadcasting and where to connect to subscribe to them.
Example use cases
Example prompt
“What ZMQ notification endpoints are currently active on the chainquery Bitcoin full node? I want to know which topics like rawblock or rawtx are being published and their addresses.”
Technical details
Endpoint
GEThttps://x402.chainquery.com/v1/rpc/getzmqnotificationsWhen to prefer
Use this endpoint when you need to discover the live ZMQ notification configuration of an independent Bitcoin full node without setting up your own node or managing API keys. It is the right choice when building a ZMQ subscriber and you need to programmatically find the correct addresses and topics, or when monitoring whether ZMQ is correctly configured on this specific chainquery node.
Side effects
- Node temporarily unavailable: returns HTTP 5xx or RPC error
- Payment not processed: returns HTTP 402 requiring x402 payment
- Invalid request format: returns 400 if method or type fields are malformed
- ZMQ not configured: result array may be empty if node has no ZMQ endpoints active
