HTTP status: 409 · Title: “Position not claimable”

​
When it fires

POST /v1/redemptions was called for a (marketId, outcomeIndex) that is not currently claimable for your account. Claimability is decided by the same rule the Kash web app uses, so any claim the API accepts can be redeemed.

​
Why it happens

  • The outcome did not win. On a resolved market only the winning outcome is redeemable. Losing-outcome tokens can still show an on-chain balance but are worthless.
  • No refund for that outcome. On a cancelled market, only outcomes with a non-zero refund price are refundable.
  • The market was redeemed automatically. It resolved before self-service redemption was available, so winning positions were redeemed to holders’ self-custodial wallets without a claim.
  • Already redeemed. The position has been redeemed, or a redemption is in progress.
  • A previous claim failed. An earlier claim for this exact position ended as failed, and a new claim cannot be created through the API for it. The detail says so explicitly.

​
How to fix

  • Redeem the winning outcome index. On a cancelled market, redeem an outcome you hold that carries a refund.
  • If the market was redeemed automatically, your USDC is already in your self-custodial wallet; check GET /v1/portfolio.
  • If a claim is in progress (not failed), repeating the request returns 200 with the original claim rather than this error.
  • If a previous claim failed, contact ZeroID support so the failed request can be retried.
