HTTP status: 404 · Title: “Market not found”

​
When it fires

The market id (a UUID) you passed doesn’t match any market. Returned by GET /v1/markets/{id}, GET /v1/markets/{id}/predictions, GET /v1/markets/{id}/quote, POST /v1/trades, POST /v1/trades/{id}/confirm and POST /v1/redemptions.

​
Why it happens

  • A typo in the market id.
  • Cross-environment confusion: a staging market id sent to production, or the reverse. Markets don’t exist across environments.
  • A placeholder id copied from documentation rather than a real one.
  • Redemptions only: the market exists but has not been created on-chain yet, so there is nothing to redeem against. POST /v1/redemptions reports this as MARKET_NOT_FOUND.

​
How to fix

  • Look up real market ids with GET /v1/markets (filterable by status).
  • Cache the id once you have it; a market’s id never changes.
  • If you expect the market to exist (for example you saw it in the Kash web app), confirm you are calling the same environment.
