Exchange Information

Type: NONE · Weight: 10

Status: Implemented.

GET /api/v3/exchangeInfo

Every active spot market with its trading filters, plus the rate-limit ceilings the gateway is enforcing for the standard tier. Not signed; takes no parameters (any query parameters, including symbol, are ignored and the full list is returned).

Read this at startup and derive order sizing from it. Only minNotional is enforced at order entry (for wallet-funded accounts, -1013); tickSize, stepSize and minQty are the market's published increments and are not validated by the gateway or trading service — round to them client-side.

Field	Type	Notes
`timezone`	string	Always `"UTC"`.
`serverTime`	number	Unix ms.
`rateLimits[]`	array	The enforced `standard`-tier ceilings (see Rate limits). `ext-mm` and `house` keys have higher ceilings than advertised here, never lower.
`symbols[].symbol`	string	Uppercase, hyphenated. Use verbatim in every other endpoint.
`symbols[].status`	string	Always `"TRADING"` for listed markets; delisted markets are omitted.
`symbols[].baseAsset`, `quoteAsset`	string	Asset names as recorded in the market registry. May contain a dot (`USDC.B`) even though the symbol does not. Casing follows the registry row and can differ from the `/api/v3/account` asset list for some markets (`CETH` here versus `cETH` in `account`); join the two case-insensitively.
`symbols[].orderTypes`	array	`LIMIT`, `MARKET`.
`filters[PRICE_FILTER].tickSize`	string	Price increment. Not validated at order entry.
`filters[LOT_SIZE].stepSize`, `minQty`	string	Quantity increment and minimum; the two are always equal. Not validated at order entry.
`filters[NOTIONAL].minNotional`	string	Minimum `price × quantity` in quote asset, enforced at order entry for wallet-funded accounts (`-1013`). `"0"` when no minimum is configured.

Errors

HTTP	code	When
`500`	`-1000`	Market registry unavailable.
`429`	`-1003`	Per-IP public weight exhausted.

Differences from Binance

Not present: baseAssetPrecision, quotePrecision, quoteAssetPrecision, baseCommissionPrecision, quoteCommissionPrecision, permissions, icebergAllowed, ocoAllowed, defaultSelfTradePreventionMode, exchangeFilters, and the PRICE_FILTER.minPrice/maxPrice, LOT_SIZE.maxQty, PERCENT_PRICE, MAX_NUM_ORDERS, MARKET_LOT_SIZE filters. Derive decimal precision from tickSize and stepSize.
rateLimits has no RAW_REQUESTS entry; per-IP limits are documented in Basic Information rather than advertised here.
Fees are not part of this payload; see On-chain Settlement for the schedule.
