Sylvia API

What it does

Sylvia API is a stateless gateway to Reddit data, offering up to 480 requests per minute free — 4.8x the official Reddit API rate limit. It provides full recursive comment threads, live firehose, historical data access, and customizable JSON response formats. No OAuth approval is needed; users get an API key in 30 seconds and pay only for successful requests ($0.0005/standard, $0.05/live).

Key Features

• High rate limits: 480 req/min free, scalable to 2,400 req/min on paid plans.
• No OAuth: Single API key header, no app registration or user auth.
• Pay per success: Only HTTP 200 OK responses are billed; failed requests are free.
• Full comment tree resolution: Recursive thread depth, not truncated at 500 items.
• Historical data access: Full archive via ?t= parameter (all, year, month, etc.).
• Custom response templates: Define your own JSON schema via dashboard and reference with ?format=custom(name).
• Multiple output formats: Default, Reddit-compatible, minimal, NDJSON, CSV, custom.
• SDKs: JavaScript, Python, Rust, plus an MCP server for AI agents.
• Crypto payments: USDT, BTC, LTC, BNB accepted; zero KYC.

Who it is for

• AI/ML researchers needing bulk training data with full thread context.
• Market analysts tracking brand sentiment and competitor mentions in real time.
• Marketing teams doing social listening at scale across subreddits.
• Journalists and investigators following breaking stories with live firehose.
• Academic researchers collecting large text corpora for social science or linguistics.
• Content creators spotting trending topics before they peak.

Why it matters

Reddit's official API caps at 100 req/min, requires OAuth approval, and silently drops requests under load. Sylvia eliminates these pain points with a simple key-based access, higher rate limits, and a transparent pay-per-success model. It enables scalable Reddit data extraction for AI training, market intelligence, and research without the overhead of managing scraping infrastructure or dealing with API limitations.

Brand and naming

The name "Sylvia" suggests a sleek, efficient alternative — a helper that cuts through bureaucracy. The tagline "Reddit data without the API drama" positions it as a developer-friendly, no-nonsense solution. The brand emphasizes speed, simplicity, and reliability, with a focus on removing friction (no OAuth, instant key, crypto payments).
