OKX polls this endpoint every second to retrieve supported pairs, the maker address, and independent price levels for the requested chain.
Request URL#
GET
https://your-api-endpoint.com/OKXDEX/rfq/pricingRequest parameters#
| Parameter | Type | Required | Description |
|---|---|---|---|
| chainIndex | String | Yes | Unique chain identifier; Solana is fixed to 501. |
Response parameters#
| Field | Type | Description |
|---|---|---|
| code | String | 0 on success. |
| msg | String | Empty on success; reason on failure. |
| data.chainIndex | String | Unique chain identifier. |
| data.levelData[] | Array | List of supported pair/depth entries. |
| .takerTokenAddress | String | Mint address of the token sold by the taker. |
| .makerTokenAddress | String | Mint address of the token bought by the taker. |
| .makerAddress | String | MM wallet used by OKX to build calldata and derive Solana ATAs. |
| .levels | Array | Independent, non-cumulative [amount, rate] entries. amount is the taker-token quantity; rate is the taker-to-maker exchange rate. |
| .minTakerAmount | String | Minimum accepted taker quantity. Omitted, null, or 0 means no minimum. Use the same unit as levels[][0]. |
Price-level rule:
levelsare independent, incremental depth entries. Each level represents only its own executable quantity and rate; do not carry prior-level quantity into later levels.
