Quote API

We highly recommand using Mayan SDK for integration as it simplfies the integration process.

Before performing a swap we need find the best route and get the swap rate for the token pair using quote API.

API Reference

Swagger UI

Example:

The request to get the quote for swapping BNB tokens from BNB Smart Chain (BSC) to receive USDC tokens on Solana would be like this:

Request:

curl -X 'GET' 'https://price-api.mayan.finance/v3/quote?solanaProgram=FC4eXxkyrMPTjiYUpp4EAnkmwMbQyZ6NDCh1kfLn6vsf&forwarderAddress=0x0654874eb7F59C6f5b39931FC45dC45337c967c3&amountIn=100&fromToken=0xb97ef9ef8734c71904d8002f8b6bc66dd9c48a6e&fromChain=avalanche&toToken=0x0000000000000000000000000000000000000000&toChain=solana&slippageBps=300&referrer=7HN4qCvG2dP5oagZRxj2dTGPhksgRnKCaLPjtjKEr1Ho&gasDrop=0&gasless=true'

List of request parameters:

Parameter	Type	Required	Description
solanaProgram	String	Yes	Mayan Wormhole Swap program address
amountIn64	String	Yes	is the token amount encoded in base units (smallest denomination), 1000000 USDC equals 1 USDC
fromToken	String	Yes	Token address of input token
fromChain	String	Yes	Wormhole chain ID of source network
toToken	String	Yes	Token address of output Token
toChain	String	Yes	Wormhole chain ID of destination network
slippageBps	Number	Yes	Maximum slippage in bps, If the output token amount exceeds the slippage the swap will refund, (Max=100)
referrer	String	No	Referrer address that receives the referrer fee
referrerBps	Number	No	Default is 0, The expected basis points the integrator intends to earn through the referral program
gasDrop	Number	No	Default is 0. the amount of gas drop that must be delivered to user on delivered on destination network
fullList	Boolean	No	Default is false, enables returning all available quote options instead of the default limited (fastest and best-return) results
destinationAddress	String	No	Helps provide a more accurate quote, for example by checking whether the Solana ATA exists.
apiKey	String	No	Defined an API that prevents the rate-limit-exceeded error on a per-IP basis.

Response:

The quote service returns an array of quotes. By default, it includes at most two items: the first is the fastest option, and the second is the best-return quote. If the fastest option also provides the best return, only one quote is returned.

It is possible to set the fullList request parameter to true to retrieve all available quote options. In this case, more than two items may be returned, and no sorting is applied. Interfaces can apply their own sorting logic by considering the etaSeconds and expectedAmountOut fields in each item.

Supported Tokens

Mayan is an intent-based protocol and supports any token as input or output, provided there is sufficient liquidity on the source or destination chains. We also maintain an approved, whitelisted token list for convenience:

Swagger UI

Example:

curl -X 'GET' \
  'https://price-api.mayan.finance/v3/tokens?chain=solana' \
  -H 'accept: application/json'

To get the aggregated list of tokens from all chains remove chain from in the query .

Supported Chains

GET sia.mayan.finance/v10/init

Returns configuration for every supported chain, including whether it can be used as a origin or destination** **chain.

Example:

curl -X 'GET' \
  'https://sia.mayan.finance/v10/init' \
  -H 'accept: application/json'

This endpoint provides a JSON response containing a comprehensive list of all chains supported by the platform. Each chain entry includes detailed metadata such as the chain’s name, chain ID, and other relevant attributes.

Two key fields indicate the chain’s functionality within the platform:

• originActive: Specifies whether the chain is supported as a source chain.
• destinationActive: Specifies whether the chain is supported as a destination chain.

Use this endpoint to determine compatibility and availability of specific chains for your operations.

API Key:

Currently, API access is provided manually. Integrators who wish to obtain an API key should send a request email to [e-mail]. After receiving the request, our team will review it and contact you to complete the process. Once approved, we will generate an API key and send it to you via email so you can start using the API
