KyberSwapAggregator_EVMAPIs_v2.10.0.yaml

Note on integration: clientID

In order to continuously improve the KyberSwap Aggregator, our APIs implement a client identifier field that enables us to understand how the APIs are being utilized. A stricter rate limit will be applied if a clientId is not provided. As a developer integrating with our APIs, please preferably use the same clientID (i.e. company name or your app name) for:

• [V1] Get Swap Route

  • Header: x-client-id

• [V1] Post Swap Route For Encoded Data

  • Header: x-client-id

This will enable us to serve you better as we continuously strive to improve our Aggregator API. For integrators who have previously integrated with our Legacy API, we highly encourage migrating to the Latest APIs to ensure access to the latest features as well as improved service quality and efficiency.

Example

• [V1] GET /routes

  • Header

    • x-client-id: MyAwesomeApp

• [V1] POST /route/build

  • Header

    • x-client-id: MyAwesomeApp

EVM swap APIs

If you're just getting started with the KyberSwap Aggregator, you can refer to our Execute A Swap With The Aggregator API dev guide for information and code samples on how to query and execute swaps at superior rates. Note that there is also a KyberSwap Widget option for integrators who require a simple minimal-code implementation. For existing integrators, please refer to Upgrading To APIv1 for further details on the motivation behind the upgrade as well as the relevant changes to swap flow and parameters.

To support more performant queries and the use of RFQ liquidity sources, KyberSwap highly encourages all integrators to implement the latest API [V1] version. While both versions of the API remains backwards compatible, only the [V1] APIs will continue to receive updates and can make use of RFQ liquidity sources, and hence developers are highly encouraged to implement the latest [V1] APIs to avoid any disruptions as the non-versioned API will eventually be deprecated.

API statuses and support

KyberSwap APIs uses the following statuses to minimize version miscommunications and ensure an uninterrupted service for the end user:

• Latest: API is functional and supported. This is the recommended version for all integrators (new and existing).

• Legacy: API remains functional with support for bugs only. No new feature updates.

• Deprecated: API is no longer functional and is not supported.

For all developers, it is highly recommended that you refer to the API with the Latest tag to ensure access to the latest features as well as improved service quality and efficiency. APIs which are planned to be sunset will be tagged Legacy during the transition period and thereafter moved to Deprecated.

The KyberSwap Docs will continue to maintain information regarding Legacy and Deprecated APIs.

Chain identifiers

The Aggregator APIs require a chain name to be included in the path when calling the APIs:

• Ethereum (ChainID: 1) -> ethereum

• BSC (ChainID: 56) -> bsc

• Arbitrum (ChainID: 42161) -> arbitrum

• Polygon PoS (ChainID: 137) -> polygon

• Optimism (ChainID: 10) -> optimism

• Avalanche (ChainID: 43114) -> avalanche

• Base (ChainID: 8453) -> base

• zkSync Era (ChainID: 324) -> zksync

• Fantom (ChainID: 250) -> fantom

• Linea (ChainID: 59144) -> linea

• Scroll (ChainID: 534352) -> scroll

• Mantle (ChainID: 5000) -> mantle

• Blast (ChainID: 81457) -> blast

• Sonic (ChainID: 146) -> sonic

• Berachain (ChainID: 80094) -> berachain

• Ronin (ChainID: 2020) -> ronin

Latest

[V1] Get Swap Route

get

Find the best route to swap from tokenIn to tokenOut, supporting all liquidity sources including RFQ. Use this API to get a route preview before confirming the swap. The route returned can then be combined with transaction specific params in the POST API payload to get the encoded data for submission to the KyberSwap router contract. Refer to Supported Exchanges And Networks for the full list of supported networks.

Path parameters

chainstringrequired

Chain name. Full list of supported chains available in Docs.

Example: ethereum

Query parameters

tokenInstringrequired

Address of the input token 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE in case of native token

tokenOutstringrequired

Address of the output token 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE in case of native token

amountInstringrequired

Amount of the input token (in wei)

includedSourcesstringoptional

DEX IDs included in the route, separated by comma

excludedSourcesstringoptional

DEX IDs excluded from the route, separated by comma

onlyScalableSourcesbooleanoptional

Exclude unscalable sources and only use sources that accept scaling input amounts

onlySinglePathbooleanoptional

Determines whether to only return single-path route

gasIncludebooleanoptional

Determines whether gas costs are accounted for when searching for best route

gasPricestringoptional

Custom gas price in wei used when searching for the best swap route. Use result from eth_gasPrice otherwise

feeAmountstringoptional

Fee amount to be collected
if isInBps = true, feeAmount is the percentage of fees to take with base unit = 10000, i.e feeAmount = 10 and isInBps = true then fee = 0.1% if isInBps = false, feeAmount is the amount of token to take as fee, i.e feeAmount = 10 and isInBps = 'false' then fee = 10 token weis

chargeFeeBystring · enumoptional

Indicates that the API client wants to charge fee by input token (currency_in) or output token (currency_out). Default is empty whereby no fee is charged.

Available options:

isInBpsbooleanoptional

if true, fee is taken in bps of the amount in/out, instead of absolute wei value

feeReceiverstringoptional

The API client's wallet address to receive fee (if chargeFeeBy is not empty)

Header parameters

X-Client-Idstringrequired

ClientID of the party calling the API. Provide a value to identify your client and avoid getting rate limited. If an even higher rate limit is needed, contact bd.

Example: MyAwesomeApp

slippageTolerancenumberoptional

This is the amount of slippage the user can accept for his trade. The unit is bps (1/100 of 1%). The value is in ranges [0, 2000], with 10 meaning 0.1%, and 0.1 meaning 0.001%. If no value is provided, slippageTolerance will be set to 0.

ignoreCappedSlippagebooleanoptional

If true, the slippage tolerance can be any value. Please use with caution.

enableGasEstimationbooleanoptional

If true, call eth_gasEstimate to get gas estimation for the transaction. Also helps to detect any potential reverts.

sourcestringoptional

The source of the swap to be recorded on-chain. You should use (and it defaults to be) the same value as the x-client-id in the header, unless you want to track separate sources.

referralstringoptional

Referral info to include in the swap transaction's ClientData event.

KyberSwap positive slippage surplus collection

For every swap executed by the KyberSwap Aggregator, users will be able to see an estimated output amount based on the current price as well as a minimum received that takes into account the max slippage setting. KyberSwap Aggregator will always strive to execute swaps at the estimated output amount and revert the transaction if the minimum received amount is not achieved.

In the event that the market moves in favor of the trade which results in a surplus of tokens above the estimated output amount (i.e positive slippage), this surplus will initially accrue to KyberSwap. Surplus sharing programs will be explored as the KyberSwap ecosystem grows to be more self-sufficient. Critically, traders will always get the estimated output amount as long as the swap is executed at or above the current rate.

Note that this surplus is different from fees as it only applies in cases where the executed swap rate is better than the estimated rate at point of transaction confirmation. Please refer to slippage for more information.
