Map over the Meld token list

Oct 13, 2025 by pynkocean.com 83 views

Description

When working with the Meld API, it's essential to have accurate and reliable price information for Meld tokens. However, the current implementation of the Meld API does not include a coingeckoId as a definition for a token. This limitation can lead to a significant number of failures when calling the getPrice API from ratios, resulting in the individual price lookup fallback instead of utilizing batch requests. To overcome this issue, we need to map over the Meld token list and call our getCoingeckoId() method. This approach will provide better price information for each token and reduce the number of calls we need to make to the getPrice API.

Understanding the Problem

The Meld API returns a list of tokens, but it does not include a coingeckoId as a definition for a token. This means that when we call the getPrice API from ratios, we have to pass either the token's symbol or contractAddress. However, this approach can lead to a significant number of failures, triggering the individual price lookup fallback instead of utilizing batch requests. This can result in a slower and less efficient price lookup process.

The Solution: Using getCoingeckoId Method

To address this issue, we need to map over the Meld token list and call our getCoingeckoId() method. This method will provide us with the coingeckoId for each token, which we can then use to call the getPrice API from ratios. By using the getCoingeckoId() method, we can reduce the number of calls we need to make to the getPrice API and improve the overall efficiency of the price lookup process.

Benefits of Using getCoingeckoId Method

Using the getCoingeckoId() method has several benefits, including:

Improved price accuracy: By using the coingeckoId for each token, we can ensure that we have accurate and reliable price information.
Reduced number of calls: By mapping over the Meld token list and calling the getCoingeckoId() method, we can reduce the number of calls we need to make to the getPrice API.
Faster price lookup: By utilizing batch requests and reducing the number of calls, we can improve the overall efficiency of the price lookup process.

Implementation

To implement the getCoingeckoId() method, we need to follow these steps:

Map over the Meld token list: We need to map over the Meld token list and call the getCoingeckoId() method for each token.
Get the coingeckoId: We need to get the coingeckoId for each token using the getCoingeckoId() method.
Use the coingeckoId to call the getPrice API: We need to use the coingeckoId to call the getPrice API from ratios.

Example Code

Here is an example of how we can implement the getCoingeckoId() method:

const meldTokens = await meldApi.getTokens();
const coingeckoIds = await Promise.all(
  meldTokens.map(async (token) => {
    const coingeckoId = await getCoingeckoId(token.symbol);
    return coingeckoId;
  })
);

In this example, we first get the list of Meld tokens using the meldApi.getTokens() method. We then map over the list of tokens and call the getCoingeckoId() method for each token. The getCoingeckoId() method returns the coingeckoId for each token, which we then store in the coingeckoIds array.

Conclusion

Q: What is the problem with the current implementation of the Meld API?

A: The current implementation of the Meld API does not include a coingeckoId as a definition for a token. This means that when we call the getPrice API from ratios, we have to pass either the token's symbol or contractAddress. However, this approach can lead to a significant number of failures, triggering the individual price lookup fallback instead of utilizing batch requests.

Q: Why is it important to use the getCoingeckoId method?

A: Using the getCoingeckoId() method is essential to improve the price lookup process for Meld tokens. By mapping over the Meld token list and calling the getCoingeckoId() method, we can reduce the number of calls we need to make to the getPrice API and improve the overall efficiency of the price lookup process. We can also ensure that we have accurate and reliable price information for each token.

Q: How does the getCoingeckoId method work?

A: The getCoingeckoId() method takes a token's symbol as input and returns the corresponding coingeckoId. This coingeckoId can then be used to call the getPrice API from ratios.

Q: What are the benefits of using the getCoingeckoId method?

A: The benefits of using the getCoingeckoId() method include:

Improved price accuracy: By using the coingeckoId for each token, we can ensure that we have accurate and reliable price information.
Reduced number of calls: By mapping over the Meld token list and calling the getCoingeckoId() method, we can reduce the number of calls we need to make to the getPrice API.
Faster price lookup: By utilizing batch requests and reducing the number of calls, we can improve the overall efficiency of the price lookup process.

Q: How can I implement the getCoingeckoId method in my code?

A: To implement the getCoingeckoId() method, you can follow these steps:

Map over the Meld token list: You need to map over the Meld token list and call the getCoingeckoId() method for each token.
Get the coingeckoId: You need to get the coingeckoId for each token using the getCoingeckoId() method.
Use the coingeckoId to call the getPrice API: You need to use the coingeckoId to call the getPrice API from ratios.

Q: What is the example code for implementing the getCoingeckoId method?

A: Here is an example of how you can implement the getCoingeckoId() method:

const meldTokens = await meldApi.getTokens();
const coingeckoIds = await Promise.all(
  meldTokens.map(async (token) => {
    const coingeckoId = await getCoingeckoId(token.symbol);
    return coingeckoId;
  })
);

Q: Can I use the getCoingeckoId method with other APIs?

A: Yes, you can use the getCoingeckoId() method with other APIs that support the coingeckoId parameter. This will allow you to utilize the benefits of the getCoingeckoId() method with other APIs as well.

Q: What are the potential issues with using the getCoingeckoId method?

A: Some potential issues with using the getCoingeckoId() method include:

API rate limits: If you are making a large number of calls to the getCoingeckoId() method, you may hit the API rate limits and experience errors.
Token not found: If the token is not found in the getCoingeckoId() method, you may experience errors.
CoingeckoId not available: If the coingeckoId is not available for a token, you may experience errors.

Q: How can I troubleshoot issues with the getCoingeckoId method?

A: To troubleshoot issues with the getCoingeckoId() method, you can:

Check the API documentation: Make sure you are using the correct API endpoint and parameters.
Check the token symbol: Make sure the token symbol is correct and matches the token in the getCoingeckoId() method.
Check the coingeckoId: Make sure the coingeckoId is available for the token.
Check the API rate limits: Make sure you are not hitting the API rate limits.
