Handling Quote Errors

When calling the /quote/v2 endpoint, various errors may be returned depending on request conditions, user input, or internal routing logic. This guide outlines the possible error codes, their meanings, and how to handle them.

Looking for errors that occur after a request is submitted? See Handling Execution Errors for fill and refund failure reasons.

Expected Errors

These are known validation and routing issues that developers should gracefully handle in their integrations:

Error Code	Description
`AMOUNT_TOO_HIGH`	The requested quote amount exceeds the maximum configured for the selected token pair. Reduce the amount (or split into smaller quotes) and retry.
`AMOUNT_TOO_LOW`	The amount provided is below the minimum threshold required for a quote.
`CHAIN_DISABLED`	The origin or destination chain is currently disabled or unsupported.
`EXTRA_TXS_NOT_SUPPORTED`	Extra transactions are not supported for this trade type.
`FORBIDDEN`	User does not have the required role or permission.
`INSUFFICIENT_FUNDS`	The user’s wallet does not have enough balance to perform the swap.
`INSUFFICIENT_LIQUIDITY`	There is not enough liquidity available to complete the swap.
`INVALID_ADDRESS`	The provided user or recipient address is not valid for the target chain.
`INVALID_EXTRA_TXS`	The total value of extra transactions exceeds the intended output.
`INVALID_GAS_LIMIT_FOR_DEPOSIT_SPECIFIED_TXS`	Deposit-specified transactions require a supported trade type and a configured gas limit. See the call execution guide.
`INVALID_INPUT_CURRENCY`	The provided input currency address is invalid or not supported.
`INVALID_OUTPUT_CURRENCY`	The provided output currency address is invalid or not supported.
`INVALID_RECIPIENT`	The provided `recipient` resolves to a supported token contract and cannot receive funds. Use a wallet address.
`INVALID_SLIPPAGE_TOLERANCE`	`slippageTolerance` (or `latePaymentSlippageTolerance`) is not an integer string in the range `0`–`10000` basis points.
`NO_INTERNAL_SWAP_ROUTES_FOUND`	No valid swap route exists internally for the selected token pair.
`NO_QUOTES`	No available quotes for the given parameters.
`NO_SWAP_ROUTES_FOUND`	No route was found to fulfill the quote request with the given parameters.
`PRICE_FETCH_FAILED`	The upstream price feed is temporarily unavailable. Retry with backoff.
`REQUEST_TIMED_OUT`	An upstream RPC provider timed out before returning a result.
`ROUTE_TEMPORARILY_RESTRICTED`	This route is temporarily restricted due to high traffic or throttling.
`RPC_HTTP_ERROR`	An upstream RPC provider returned a transient infrastructure error.
`SANCTIONED_CURRENCY`	The token involved in the transaction is on a sanctions list.
`SANCTIONED_WALLET_ADDRESS`	The sender or recipient wallet address is sanctioned or blacklisted.
`SERVICE_UNAVAILABLE`	Relay is experiencing a transient infrastructure issue. Retry with backoff.
`SOLANA_TX_TOO_LARGE`	The compiled Solana deposit transaction exceeds Solana’s 1232-byte wire limit and cannot be signed or broadcast. The response `message` reports the measured size and how many bytes it lands over. For ways to reduce this error, see Solana Support.
`SWAP_IMPACT_TOO_HIGH`	The swap’s price impact exceeds acceptable thresholds. See Overriding Price Impact Protection.
`UNAUTHORIZED`	The user is not authenticated or lacks valid authorization.
`UNAUTHORIZED_QUOTE`	The quote request includes a `referrer` but no valid `x-api-key` header.
`UNSUPPORTED_CHAIN`	The specified chain is not supported by the platform.
`UNSUPPORTED_CURRENCY`	The specified currency is not supported for input or output, or the token pair cannot be priced.
`UNSUPPORTED_EXECUTION_TYPE`	The execution type used is not supported for fee estimation or execution.
`UNSUPPORTED_ROUTE`	The swap route combination is not supported.
`USER_RECIPIENT_MISMATCH`	User and recipient addresses must match for this type of swap.

PRICE_FETCH_FAILED, REQUEST_TIMED_OUT, RPC_HTTP_ERROR, and SERVICE_UNAVAILABLE all indicate transient upstream infrastructure issues, not problems with your request. PRICE_FETCH_FAILED and SERVICE_UNAVAILABLE are returned with HTTP 503; REQUEST_TIMED_OUT and RPC_HTTP_ERROR are returned when upstream RPCs are classified as transient. Retry with backoff before surfacing a failure to the user.

Overriding Price Impact Protection

Relay rejects a quote with SWAP_IMPACT_TOO_HIGH when the swap’s price impact exceeds its protection threshold. The guard protects users from receiving far less than the reference value of their input, but it also blocks swaps where high impact is genuine and expected — most commonly newly launched or thin-liquidity tokens. To accept the impact and receive the quote anyway, pass overridePriceImpact in the quote request:

{
  "user": "0x03508bB71268BBA25ECaCC8F620e01866650532c",
  "originChainId": 8453,
  "originCurrency": "0x0000000000000000000000000000000000000000",
  "destinationChainId": 8453,
  "destinationCurrency": "0x833589fcd6edb6e08f4c7c32d4f71b54bda02913",
  "tradeType": "EXACT_INPUT",
  "amount": "10000000000000000",
  "overridePriceImpact": true
}

With the override enabled, the quoted output can be far below the reference value of the input. Surface details.totalImpact from the quote response in your UI and require explicit user confirmation before execution. The override only bypasses the impact check — it does not help when no route is returned at all (NO_SWAP_ROUTES_FOUND).

Unexpected Errors

These indicate infrastructure or downstream failures and are not common:

Error Code	Description
`DESTINATION_TX_FAILED`	The relay transaction reverted on the destination chain.
`ERC20_ROUTER_ADDRESS_NOT_FOUND`	The router contract for a token could not be located.
`UNKNOWN_ERROR`	An unclassified or unexpected error occurred.
`SWAP_QUOTE_FAILED`	Failed to calculate a quote, possibly due to third-party pricing failure.
`PERMIT_FAILED`	Permit signature validation failed for token approvals.
