Data Requested Is Before Recorded History (before_history)

HTTP 410Horizon RFC 7807 ProblemCode: before_history

Type URI: https://orion.stellarchain.io/horizon-errors/before_history

The requested ledger or cursor predates the earliest ledger retained by this instance.

Quick Fix & Resolution

On https://pubnet.stellarchain.io, full history is retained back to genesis (history_elder_ledger: 3) in Cloudflare R2 Parquet storage. Ensure ledger sequence is >= 3.

Response Payload & SDK Handling

RFC 7807 JSON Response

{
  "type": "https://orion.stellarchain.io/horizon-errors/before_history",
  "title": "Data Requested Is Before Recorded History",
  "status": 410,
  "detail": "This horizon instance is configured to only track a portion of the stellar network's latest history. This request is asking for results prior to the recorded history known to this horizon instance."
}

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/before_history') {
    console.error('[before_history] HTTP 410:', 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 == 410 {
        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

• Requesting a ledger sequence prior to the node's history_elder_ledger.
• Supplying a paging cursor that points to a ledger prior to recorded history.
