Data Details

• logo: Returns a string URL or null if no branding is available.

• Supported URL Keys: website, telegram, twitter, discord, facebook, instagram, reddit, tiktok, github.

Use Cases

1. Project Directories: Fetch the dataset to render a browsable catalog of uDegen-verified assets with full branding and social links.

2. Instant Search: Load the dataset client-side to enable per-keystroke filtering and autocomplete without repeated API latency.

3. Portfolio Enrichment: Match user wallet addresses against our list to display rich metadata (logos, names) for verified holdings.

4. Community Bots: Integration for Telegram/Discord bots to display social links for verified projects upon user command.

Example Integration (TypeScript)

TypeScript

type CoinUrls = Partial<{
  website: string; telegram: string; twitter: string;
  discord: string; facebook: string; instagram: string;
  reddit: string; tiktok: string; github: string;
}>;

type Coin = {
  network: string;
  address: string;
  name: string;
  symbol: string;
  logo: string | null;
  urls?: CoinUrls;
};

type CoinsResponse =
  | { success: true; data: Coin[] }
  | { success: false; error: string; };

async function fetchListedCoins(): Promise<Coin[]> {
  const res = await fetch("https://udegen.io/api/coins");
  const json: CoinsResponse = await res.json();

  if (!json.success) throw new Error(json.error);

  return json.data;
}

Technical Implementation Notes

• Clean URL Data: Our backend uses a Zod transform to strip out null or empty URL fields. If a key like twitter exists in the response, you are guaranteed a valid URL string.

• Cache Strategy: The system uses the Redis key coins:listed. The first request after the 1-hour TTL triggers a database repopulation.

• Payload Considerations: Currently, this endpoint returns the entire verified dataset. Future versions may include pagination as the list of uDegen-verified projects grows.
