DEX Aggregator - XOXNO Docs

Use the Aggregator to quote MultiversX swaps and, when sender is present, receive transaction data your wallet can sign.

Use This When

Need	Use
Price a swap before the user signs	`GET /api/v1/quote` with `amountIn` or `amountOut`
Build transaction data for a wallet flow	Add `sender` to the quote request
Check token decimals and minimum input	`GET /api/v1/pair-config` before quoting
Detect a same-token arbitrage cycle	Set `from` and `to` to the same token

Need	Use instead
You need account, nonce, or transaction status data	Gateway
You already signed the transaction and only need propagation	Relayer broadcast
You need Stellar routes or a Stellar `TransactionEnvelope`	Stellar Aggregator

No API key is required; per-IP rate limits apply.

Validate the pair

Call /api/v1/pair-config to confirm supported: true, read token decimals, and check minAmountIn.

Quote the route

Call /api/v1/quote with exactly one amount field: amountIn for forward quotes or amountOut for reverse quotes.

Request transaction data

Pass sender when the user is ready to sign. The response can include a full transaction object and encoded txData.

Sign and broadcast

Sign the returned transaction with the user’s wallet, then broadcast it through the wallet, Gateway, or Relayer.

Action	Limit or behavior
Any request	100 requests per second per IP
Quote freshness	Quotes use the latest pool snapshot available to the service
Liquidity sources	xExchange, AshSwap, JEX, OneDex
Transaction data	Do not reuse `txData` across quote requests
Amount format	Use integer strings in the token’s smallest unit

Token decimals vary by asset. Convert from human-readable amount to smallest unit before quoting, and verify decimals with /api/v1/pair-config.

Endpoint	Method	Job
`/api/v1/quote`	`GET`	Quote a route and optionally return transaction data
`/api/v1/pair-config`	`GET`	Validate support and return decimal metadata
`/health`	`GET`	Check service health

Validate a pair, fetch a quote, and inspect the transaction fields.

Required params, response fields, errors, and executable examples.

Confirm token support, decimals, and minimum input.

Wire quotes into a signing and broadcast flow.
