Frequently Asked Questions:

Why is the ‘balance’ value so large in my response?
The balance fields are denominated in Wei. To get the standard unit in Eth, do the following calculation: balance/10^contractDecimal
What is the current API rate limits?
Free tier: 4 requests per second.
Paid tier(hasn't enabled yet): 50 requests per second.
What do the following error codes mean?
404: Page Unavailable - The API server cannot find the requested API resource. Check your request endpoint.
406: Address Will Predictably Timeout - The API returns this error for addresses where requests will likely timeout due to, as an example, too many transactions associated with the address.
429: Too Many Requests - The client has surpassed its rate limit. This may also be indicated by the server 503: Network Error.
500: Request Timeout - This error response is given when the query will take longer than approximately 90 seconds.
503: Network Error - The API server cannot handle the request at the time, which might be due to a high number of concurrent requests or if a server is momentarily down. Retry your request in a couple minutes or reduce the number of concurrent requests.
507: Insufficient Storage - The API server is unreachable to new queries as the backlog of existing queries is full. We are likely aware of the issue and reviewing the queries consuming the resources.
562: Failed to connect to upstream third-party service - The API server can’t reach the external server where the data is hosted at the moment. This is intentionally done in order to avoid returning erroneous data.
How do I fix the CORS header ‘Access-Control-Allow-Origin’ missing error?
CORS is an HTTP header-based mechanism that allows a server to indicate any origins (domain, scheme, or port) other than its own from which a browser should permit loading resources. If you are running your app locally on localhost, you may run into this error when trying to make API calls.
One workaround is to use this extension.
Why is the logo_url sometimes missing in the response of Balances endpoint?
We fetch the logos from the Trust Wallet repository. If your logo is not available there, the token balances endpoint will not be able to fetch it.
Use the Trust Wallet Assets web app to add your token and corresponding logo.
Why does the call to Get token balances for address sometimes timeout when using the nft=true option?
Timouts using the nft=trueoption are likely due to corresponding timeouts with an external service call made by our API to fetch the NFT metadata. You can confirm this by making the same call and setting no-nft-fetch=trueand see if that returns successfully.
