specters 2.0.0

Python bindings for Specter HTTP client with TLS/HTTP2/HTTP3 fingerprint control

Specter

Python bindings for the Specter HTTP client - an HTTP client that accurately replicates Chrome's TLS and HTTP/2 behavior.

Installation

pip install specters

Features

• HTTP/1.1, HTTP/2, and HTTP/3 support
• Chrome 142 TLS fingerprint (BoringSSL)
• Chrome HTTP/2 fingerprint (SETTINGS, pseudo-header order, GREASE)
• Async/await interface
• Cookie jar with Netscape format support

Usage

import asyncio
from specter import Client, FingerprintProfile

async def main():
    client = Client(fingerprint=FingerprintProfile.Chrome142)

    response = await client.get("https://example.com")
    print(f"Status: {response.status}")
    print(f"Body: {response.text()}")

asyncio.run(main())

Force HTTP version

from specter import HttpVersion

# HTTP/2 only
response = await client.get(url, version=HttpVersion.Http2)

# HTTP/3 with fallback
response = await client.get(url, version=HttpVersion.Http3)

Custom headers and cookies

from specter import CookieJar

jar = CookieJar()
await jar.load_from_file("cookies.txt")

response = await client.get(url, cookies=jar)
jar.store_from_headers(response.headers, url)

await jar.save_to_file("cookies.txt")
