+  also contains metadata (they can, however, be excluded by setting <code>excludeMetadata</code>

+
+  <li>If not specified, the API returns balances for all supported types of tokens
+  (fungible tokens, nft, multitokens), but you can also choose to filter specific
+  <code>tokenTypes</code>.</li>
+
+  <li>For Tezos blockchain, the API returns balance of any tokens including native
+  token (XTZ) for specified wallet addresses. Following query parameters won''t have

+
+  <ul>
+
+  <li>To improve response times and obtain specific data, it is recommended to use
+  proper filtering techniques. Please provide a chain name and a combination of filters
+  that will accomplish this (at least block range or contract addresses must be specified).</li>
+
+  <li>It is possible to specify multiple contract addresses at once by passing them
+  as a comma separated string.</li>
+
+  <li>If block range is not specified, the API attempts to go through all available
+  blocks, which may result in a timeout error.</li>
+
+  <li>It is recommended to filter only one specific type of events, which comes with
+  built-in decoding for all the supported types.</li>
+
+  <li>It is, however, also possible to filter by signature hashes, which can be passed
+  together as a comma separated string.</li>
+
+  </ul>
+
+  <p>As noted above, aside from general info and hashed event data, the API also decodes
+  them for you in case you filter by one of the following supported event types:</p>
+
+  <ul>
+
+  <li><code>tokenTransfer</code>: All transfers of fungible tokens (including stablecoins)
+  and NFTs as per ERC-20 and ERC-721 standard.</li>
+
+  <li><code>multitokenTransfer</code>: All transfers of multitokens (both single transfers
+  and batch transfers) as per ERC-1155 standard.</li>
+
+  <li><code>stablecoinTransfer</code>: Refers to the transfer of specific stablecoins
+  on the mainnet. Typically, the top 10 to 16 stablecoins on each chain according
+  to CoinMarketCap are included. If the <code>contractAddresses</code> parameter is
+  also used in the filter combination, any tokens specified in it will also be included
+  in the list.</li>
+
+  <li><code>uniswapTrade</code>: Provides all swap events that occur on both Uniswap
+  V2 and V3. In some cases, it may not be possible to map the swapped amounts to specific
+  tokens. As a result, certain decoded data such as token amounts might be missing
+  or in the original big number format. This will be indicated by the response parameter
+  <code>partiallyRaw: true</code>.</li>

+
+  <li>Celo - celo / celo-testnet</li>
+
+  <li>Ethereum - ethereum / ethereum-sepolia</li>

+
+  <li>Horizen EON - eon-mainnet</li>
+
+  <li>Chiliz - chiliz-mainnet</li>
+
+  </ul>
+
+  <p>To get started:</p>
+
+  <ul>
+
+  <li>Provide a chain name, token address and comma-separated list of IDs. Our API
+  will return relevant metadata about each specified token, including its name, description,
+  image, and more.</li>
+
+  <li>Aside from the metadata information, the response also contains token types
+  and metadata url minted in each token.</li>
