HTTP Endpoints

The server starts a plaintext HTTP listener on httpPort (no TLS) and serves server-info, the resource manifest and resource file endpoints. The listener lives in src/network/CNetworkManager.cpp (HTTPServerThread); the launcher fetches this before GTA connects, while the in-game client receives the same manifest over the encrypted session.

Request Handling

Routing is by path only. The HTTP method is parsed but does not change behavior — any supported method on the same path returns the same response (there is no separate HEAD/OPTIONS handling and no 405 response).

Situation	Response
Malformed request line or oversized headers	400 Bad Request
Advertised resource file found	200 OK (application/octet-stream)
Resource file not in the advertised list	404 Not Found
Any other path	200 OK with the server-info JSON

JSON and file responses carry an Access-Control-Allow-Origin: * header.

Endpoints

Path	Purpose
/resources/manifest.json	Resource manifest with file hashes and resource config
/resources/files/<resource>/<path>	Client-accessible resource file
/assets/<resource>/<path>	Asset-pack file
/stream/<resource>/<path>	Stream file for dlc/rpf resources
any other path (/, /server-info.json, unknown)	Server-info JSON (fallback)

There is no dedicated route for /server-info.json: server-info is the fallback response for any path that does not match the manifest or resource-file routes. As a result /, /server-info.json and unknown paths all return the same server-info JSON rather than a 404.

server-info.json

The server-info JSON is built inline in HTTPServerThread and contains exactly these fields:

Field	Type	Value
name	string	server display name
players	number	admitted player count
maxPlayers	number	player cap
gamemode	string	gamemode name
protocol	number	protocol version (11)
build	number	client build version (10000)
gtaBuild	number	supported GTA build (3788)
channel	string	release channel/branch
minClientBuild	number	minimum accepted client build
useEarlyAuth	bool	early-auth enabled
earlyAuthUrl	string	early-auth URL
useCloudAuth	bool	cloud-auth enabled

There is no serverId, identityMode, host/port, connection/queue counts, password state, tags, language, tick rate or streaming distance — only the fields listed above are exposed.

resources/manifest.json

The manifest is built in CResourceManager::BuildManifestJson and served as a string. An empty manifest is returned as {"schema":1,"files":[],"totalFiles":0,"totalBytes":0,"resources":[]}.

Top-level fields:

• schema — schema version (1)
• files — flat list of client-accessible files
• totalFiles, totalBytes — counts across all files
• resources — list of resources with config

Each files[] entry: resource, path, url, size, stream (bool), sha256 and an optional enc (encryption marker for encrypted-at-rest files).

Each resources[] entry: name, type, clientType, assetsBase, streamBase, an optional clientMain, plus the arrays exports, dependencies, clientFiles, dataFiles ({path, type}) and a config object.

The manifest does not contain an engine version, protocol, server name or gamemode — those values live in the server-info JSON, not the manifest.
