## Network Support | Network | HTTPS | WSS | | - | - | - | | Pubnet: Horizon (90 day history) & Stellar RPC (60 day history) | ✅ | ❌ | | Testnet: Horizon (full history since the latest testnet reset) & Stellar RPC (7 day history) | ✅ | ❌ | | Pubnet Archive: Horizon only (1 year history) | ✅ | ❌ | | Pubnet RPC v2 (Beta): Stellar RPC only (full history from ledger 2) | ✅ | ❌ | > **History retention:** Horizon on Pubnet lets you query the most recent 90 days of history, and the Pubnet Archive endpoint extends this to 1 year (the archive endpoint serves Horizon only; Stellar RPC is not available on it). Stellar RPC (formerly Soroban) serves the most recent 60 days of history on Pubnet and the most recent 7 days on Testnet. Pubnet RPC v2 (Beta) serves Stellar RPC with full Pubnet history, back to ledger 2 in September 2015. Horizon on Testnet serves full history back to the most recent Stellar testnet reset; the Stellar Development Foundation periodically resets testnet, and history restarts from each reset. ## Stellar RPC v2 (Beta) Stellar RPC v2 is the Stellar Development Foundation's full-history version of Stellar RPC. It serves every Pubnet ledger since ledger 2, so `getTransaction`, `getTransactions`, `getLedgers` and `getEvents` can read any Pubnet ledger. To use it, create an endpoint and select the **Pubnet RPC v2 (Beta)** network. Your endpoint URL is `https://pubnet.stellar.validationcloud.io/v1/`. A Pubnet RPC v2 key only works on that URL, and a Pubnet key only works on `mainnet.stellar.validationcloud.io`. Stellar RPC v2 is compatible with existing Stellar RPC clients. No method, parameter or response field was removed. The differences are: * **Full history.** Requests for old ledgers succeed instead of returning an out-of-range error. * **`getHealth`** returns `ledgerRetentionWindow: 0` because the node keeps full history. Use `oldestLedger` to find the oldest ledger served. * **`getLedgers`** returns at most 20 ledgers per page, with a default of 5. Stellar RPC on Pubnet and Testnet allows up to 200, with a default of 50. A `limit` above 20 returns an error. * **New method:** [queryEvents](/nodeapi/stellar/stellar-rpc-formerly-soroban-api/queryevents) adds newest-first ordering, positional topic filters and stateless cursors. * **No Horizon.** Pubnet RPC v2 serves Stellar RPC only. For Horizon, use a Pubnet or Pubnet Archive endpoint. Stellar RPC v2 is in beta. The Stellar Development Foundation's full list of changes is [here](https://github.com/stellar/stellar-rpc/blob/archive-node-beta/docs/API-CHANGES-BETA.md). ### Stellar SSE Streaming We recently introduced an updated Compute Unit (CU) model for **Server-Sent Events (SSE)** streaming on Stellar Horizon API endpoints. SSE allows developers to receive real-time updates without the need for continuous polling. **Pricing Model** SSE-enabled Stellar endpoints use a two-part pricing structure: * **Base cost per request:** 20 CUs (same as standard Stellar endpoints) * **Data streaming cost:** 1 CU per KB of data streamed to the client This differs from standard Stellar endpoints, which only charge the base request cost and do not include any data-based pricing. **Compute Unit Calculation** ``` Total CUs = (20 × number of requests) + (1 × response size in KB) ``` ``` Total CUs = (cu_amount × requests) + ((response_size_bytes / 1024) × cu_per_kb) ``` **Key Difference** * **Standard endpoints:** Fixed cost per request (no data-based charges) * **SSE endpoints:** Base request cost plus variable cost based on streamed data volume ## Getting Started Send a request to check that your endpoint works. Replace `` with the key from your endpoint in the [Validation Cloud app](https://app.validationcloud.io/node). ```bash title="mainnet" theme={"theme":{"light":"github-light","dark":"github-dark-default"}} curl https://mainnet.stellar.validationcloud.io/v1/ \ -X POST \ -H "Content-Type: application/json" \ -d '{"jsonrpc": "2.0", "id": 8675309, "method": "getHealth"}' ``` ```bash title="testnet" theme={"theme":{"light":"github-light","dark":"github-dark-default"}} curl https://testnet.stellar.validationcloud.io/v1/ \ -X POST \ -H "Content-Type: application/json" \ -d '{"jsonrpc": "2.0", "id": 8675309, "method": "getHealth"}' ``` ## Compute Units ### SSE Streaming Endpoints Certain Stellar Horizon endpoints support **Server-Sent Events (SSE)**, allowing clients to receive real-time updates instead of polling. > **Compute Units:** When used in streaming mode, these endpoints are charged at **20 CUs per request** plus **1 CU per KB of data streamed**. The following endpoints support SSE streaming: *** **Top-level endpoints** * GET /ledgers * GET /transactions * GET /operations * GET /payments * GET /effects * GET /trades *** **Account-specific endpoints** * GET /accounts/\{account\_id}/transactions * GET /accounts/\{account\_id}/operations * GET /accounts/\{account\_id}/payments * GET /accounts/\{account\_id}/effects * GET /accounts/\{account\_id}/trades * GET /accounts/\{account\_id}/offers *** **Ledger-specific endpoints** * GET /ledgers/\{ledger\_sequence}/transactions * GET /ledgers/\{ledger\_sequence}/operations * GET /ledgers/\{ledger\_sequence}/payments * GET /ledgers/\{ledger\_sequence}/effects *** **Liquidity pool endpoints** * GET /liquidity\_pools/\{liquidity\_pool\_id}/effects * GET /liquidity\_pools/\{liquidity\_pool\_id}/trades * GET /liquidity\_pools/\{liquidity\_pool\_id}/transactions * GET /liquidity\_pools/\{liquidity\_pool\_id}/operations *** **Transaction & operation endpoints** * GET /operations/\{operation\_id}/effects * GET /transactions/\{transaction\_id}/operations * GET /transactions/\{transaction\_id}/effects *** **Offer endpoints** * GET /offers/\{offer\_id}/trades *** **Claimable balance endpoints** * GET /claimable\_balances/\{claimable\_balance\_id}/transactions * GET /claimable\_balances/\{claimable\_balance\_id}/operations ###
