How this service works
Recent beacon slots, including the ones no block was proposed for. PulseChain (chain id 369). $0.003 USDC per call.
Output
A paginated list of recent beacon chain slots on PulseChain (chain id 369), each entry indicating the slot number, whether a block was proposed, and related metadata. Missed slots (where no validator submitted a block) are included, making it possible to identify gaps in block production.
Example use cases
Missed slot monitoring dashboard
“Show me the most recent 50 beacon slots on PulseChain and flag which ones had no block proposed — I want to track missed slot frequency.”
Validator performance investigation
“Fetch recent PulseChain beacon slots and include the missed ones so I can see if there's been an uptick in validators skipping their proposals lately.”
Paginated slot history review
“Get me the next page of recent PulseChain beacon slots starting from cursor position 'abc123', limit 25, and include missed slots too.”

Endpoint
GEThttps://x402.pulsescanner.io/v2/slots?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need beacon slot-level data for PulseChain specifically, including visibility into missed/empty slots. It is ideal for monitoring consensus-layer health, auditing validator proposal rates, or building dashboards that track slot production over time. Prefer this over block-level endpoints when you need to see gaps (missed slots) in the chain history, not just confirmed blocks.
Side effects
- Invalid cursor value returns an error or empty result
- Unsupported query parameters cause a 400 bad request
- Payment not attached or insufficient causes a 402 Payment Required response
- Rate limiting or upstream node issues may cause temporary 503 errors
- Requesting a very large limit may be capped or return partial results
