# Read throughput

## Buy

GET https://keespecs.xyz/api/pulse. No query. 0.01 USDC. Free while payments are down (rate-limited). The dashboard shows the same numbers for free.

## Which number is live

- feed.last60sTps is operations on blocks from the last minute. If feed.last60sPartial is true, this page of blocks is shorter than a minute and the rate can read low.
- feed.last60sBlocksPerSec is blocks in that same minute, divided by 60. It is not operations per second.
- ledger.lifetimeTps is total transactions divided by seconds since 22 Sep 2025. It is not the live rate.
- feed.busiestSecond is the busiest one-second bucket in this page of blocks. It is not a network record.
- ledger.transactionCount and ledger.blockCount are totals. Poll them if you need a change over time.
- If feed is null, recent blocks did not load. last60sTps is then absent. Do not treat that as zero.
- The design target is 10 million tx/s. A 2025 stress test reached 11,122,116 tx/s. Neither is live.

## Settlement time

- GET https://keespecs.xyz/api/settlement. No query. 0.01 USDC. Free while payments are down (rate-limited).
- medianMs and p95Ms are the median of the per-representative medians and p95s, in milliseconds. Only representatives with at least 100 samples in the window are included.
- samples is the settlement times inside the window, not the lifetime histogram. asOf is when this copy was read. windowS is the window length in seconds. reps lists each representative.
- source is how many representatives answered. worstRepP95Ms is the slowest included representative. repsOk is how many cleared 100 samples.
- A p95 over 5 seconds is one slow window. Settlement fails only after two slow windows at least 5 minutes apart. note is one slow window when the first one is slow.
