Authorizations

X-Kairos-Partner-Id

string

header

required

Wallet API partner id, issued by Kairos together with the partner's base URL. Identifies the partner (tenant) on every /v3 call; sent instead of an API key. Letters, digits and ._:-, at most 64 characters, case-insensitive. A partner id issued for an individual account cannot be sent this way — that account sends its API key triple instead.

Headers

X-Kairos-Wallet-Api

enum<string>

required

Wallet API contract version. Send 2 — the multi-venue contract this reference documents. Without the header (or with any other value) /v3/actions and /v3/wallets/* serve the original Polymarket-only contract, which ignores venue prefixes, expiresAt and setup.venues, omits chainId, venue and fallbackRequests from steps, refuses orders on a wallet that is not set up (409), and returns snake_case order and position rows.

Available options:

2

Path Parameters

string<uuid>

required

Action id returned by POST /v3/actions.

Response

The current step.

The current step of an action. Every response from /v3/actions and /v3/actions/{id} is one of these.

string<uuid>

required

Action id. One id for the whole action, across venues.

type

enum<string>

required

Available options:

setup,

order,

cancel,

login

status

enum<string>

required

needs_signature — run request and answer; working — poll; done — read result; failed — read error and errorCode.

Available options:

needs_signature,

working,

done,

failed

request

object | null

required

What the wallet must run. Non-null only while needs_signature.

Show child attributes

Example:

{
  "method": "personal_sign",
  "params": [
    "0x6b6169726f732e7472616465207761…",
    "0x8ba1f109551bD432803012645Ac136ddd64DBA72"
  ]
}

description

string | null

required

Text to show with the wallet prompt (e.g. Confirm this Hyperliquid order), or progress text while working.

chainId

string | null

required

EIP-155 chain id (hex) the wallet must be on to answer — 0x89 Polygon, 0x38 BNB Chain, 0xa4b1 Arbitrum One (0x66eee Arbitrum Sepolia on Hyperliquid testnet). null for personal_sign and when nothing is asked.

Example:

"0x38"

venue

enum<string> | null

required

Venue of the current prompt; null when finished and on cancels.

Available options:

polymarket,

predictfun,

hyperliquid

result

object

required

Outcome on done (and the provisional outcome of a held order). Shape depends on type.

Option 1
Option 2
Option 3
Option 4

}

error

string | null

required

Why the action failed; non-null on failed.

fallbackRequests

object[]

Present with wallet_sendCalls requests only — the same calls as individual eth_sendTransaction requests, for wallets without EIP-5792. Send them in order and answer with {"result": ["0xhash", …]}.

Show child attributes

expiresAtMs

integer<int64>

Last accepted millisecond (Unix ms) for answering this prompt. Answers after it fail the action with SIGNATURE_EXPIRED.

Example:

1793130772999

holdUntilMs

integer<int64>

On a working order the venue is still matching — poll again after this time (Unix ms). result then holds a provisional outcome with final: false.

errorCode

enum<string>

Machine-readable reason on a failed step; the key is omitted when the failure has no code. Codes may be added; treat an unknown code as a failure whose order was not placed.

Code	Meaning	Order placed?
`NO_MATCH`	An immediate order (FOK/FAK/IOC) found nothing to match.	No
`VENUE_REJECTED`	The venue refused the order.	No
`ORDER_OUTCOME_UNKNOWN`	The submission's outcome is unknown. Read the wallet's orders before placing again.	Maybe
`CANCEL_OUTCOME_UNKNOWN`	Some venue may have cancelled. Read the wallet's orders.	Maybe
`SIGNATURE_EXPIRED`	The signing window closed before a signature was accepted. Nothing was sent.	No
`CLIENT_ORDER_ID_CONFLICT`	The `clientOrderId` names an order with different terms.	No
`HYPERLIQUID_AGENT_MISSING`	Hyperliquid no longer lists this wallet's trading approval. Run `setup` again.	No

Available options:

NO_MATCH,

VENUE_REJECTED,

ORDER_OUTCOME_UNKNOWN,

CANCEL_OUTCOME_UNKNOWN,

SIGNATURE_EXPIRED,

CLIENT_ORDER_ID_CONFLICT,

HYPERLIQUID_AGENT_MISSING
