HTTP status: 422 · Title: “Market not quotable”

​
When it fires

GET /v1/markets/{id}/quote asked the market’s on-chain program for a price and it refused: it cannot price this request in its current on-chain state. A typical cause is market state that makes the pricing maths fail (for example a division by zero). This is the market’s own, deterministic answer. Sending the same request again gets the same answer until the market’s on-chain state changes.

​
Why it is not a 503

DEPENDENCY_UNAVAILABLE (503) means the API could not read the chain at all (a timeout, a transport error, a provider rate limit), so retrying can help. MARKET_NOT_QUOTABLE means the read succeeded and the market refused, so retrying cannot help. That makes it a 4xx.

​
How to fix

  • Don’t retry the same quote in a loop.
  • Check the market with GET /v1/markets/{id}. If it does not accept trades, you get MARKET_NOT_TRADEABLE instead.
  • Try a different outcomeIndex or amount; a refusal can be specific to one request.
  • If a tradeable market refuses every quote, report it to Kash support with the requestId.
