All Moralis plans have generous limits on the number of requests you can make. How many included compute units you have depends on the plan you have, check the pricing page for more details.
​

In most cases, one request to the Web3API counts as one request towards your monthly quota (also called the Base). However, some API requests are very computationally heavy and therefore count as several compute units.

See the page Compute Units for details about requests and how they are calculated.
​
​Note: for exact rate limit values the endpoint <https://deep-index.moralis.io/api/v2/info/endpointWeights> can be used.

Note: /nft/{address}/{token_id}/metadata/resync has a billing cost of 5 and a rate limit cost of 25, meaning that you can call it only once per second with a free plan and twice a second with a Pro plan
