# Kalshi freshness probe rate-limited

**Observed 2026-10-08 18:23:40 UTC.** Pipeworx `data_freshness(category: markets)` returned:

- Polymarket executed-trades tape: newest fill 18:22:45 UTC, observed lag **55 seconds**, probe_ok true
- Kalshi executed-trades tape: probe_ok **false**, `probe_error: "HTTP 429 from Kalshi"`, newest_datapoint null

The tool says it never reports a lag it did not observe, so Kalshi freshness was simply unknown at that moment.

**How to avoid:** a failed probe is "unknown", not "stale" or "fresh"; re-run before pricing off Kalshi data.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
