TypeScript (@stellar/stellar-sdk)

import { Horizon } from '@stellar/stellar-sdk';

const server = new Horizon.Server('https://pubnet.stellarchain.io');

try {
  const res = await server.ledgers().limit(10).call();
} catch (err: any) {
  const problem = err?.response?.data;
  if (problem?.type === 'https://orion.stellarchain.io/horizon-errors/invalid_accounts_params') {
    console.error('[invalid_accounts_params] HTTP 400:', problem.detail, problem.extras);
  }
}

Go (horizonclient)

client := &horizonclient.Client{
    HorizonURL: "https://pubnet.stellarchain.io",
}
_, err := client.Root()
if hErr := horizonclient.GetError(err); hErr != nil {
    if hErr.Problem.Status == 400 {
        log.Printf("Problem (%s): %s - extras=%v", hErr.Problem.Type, hErr.Problem.Detail, hErr.Problem.Extras)
    }
}

cURL Diagnostic

curl -i -s "https://pubnet.stellarchain.io/" \
  -H "Accept: application/hal+json"

Common Root Causes

• Calling GET /accounts with no filter parameters.
• Calling GET /accounts with multiple conflicting filter parameters simultaneously (e.g. both signer and asset).
