If not set, all liquidity protocols will be used<br>e.g.: <code>&#x26;protocols=</code><br><code>default: all protocols can be used</code></td></tr><tr><td><code>gasPrice</code></td><td>string</td><td>VulpeFI takes in account gas expenses to determine exchange route. It is important to use the same gas price<br>on the quote and swap methods<br>gas price set in wei: <code>12.5 GWEI</code> set as <code>12500000000</code><br><code>default: "fast" from the network</code></td></tr><tr><td><code>complexityLevel</code></td><td>string</td><td>maximum number of token-connectors to be used in a transaction. The more is used — the longer route estimation will take, the more complex route might be as a result. If not set, two token-connectors might be used<br><code>min: 0;</code> <code>max: 3;</code> <code>default: 2</code></td></tr><tr><td><code>connectorTokens</code></td><td>string</td><td>token-connectors can be specified via this parameter. The more is set — the longer route estimation will take. If not set, default token-connectors will be used. If token you want to exchange doesn't have a pool with one of the default token-connectors, this parameter will help find the route; should be the same for a quote and swap e.g.:<br><code>&#x26;connectorTokens=0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, 0x...xxx example</code><br><code>default: list of default token-connectors</code></td></tr><tr><td><code>gasLimit</code></td><td>integer</td><td>maximum amount of gas for a swap;<br>should be the same for a quote and swap<br><code>default: 11500000;</code> <code>max: 11500000;</code></td></tr><tr><td><code>mainRouteParts</code></td><td>integer</td><td>limit maximum number of main route parts;<br>should be the same for a quote and swap<br><code>default: 20;</code> <code>max: 50;</code></td></tr><tr><td><code>parts</code></td><td>integer</td><td>limit maximum number of parts each main route part can be split into; should be the same for a quote and swap<br><code>default: 20;</code> <code>max: 100;</code></td></tr></tbody></table>
