Community Provider: openbb-adanos — Stock Sentiment from Reddit, X/Twitter & Polymarket

[alexander-schneider]

Summary

We've built a community provider extension for OpenBB that adds stock sentiment data from three social/prediction market sources:

• Reddit — 50+ stock subreddits (r/wallstreetbets, r/stocks, r/investing, ...)
• X/Twitter — Tweet-level sentiment analysis
• Polymarket — Prediction market prices, liquidity, and trade activity

PyPI: openbb-adanos
GitHub: adanos-software/openbb-adanos
API Docs: api.adanos.org/docs

Installation

pip install openbb-adanos

from openbb import obb
obb.user.credentials.adanos_api_key = "sk_live_..."

Free API keys available at adanos.org/reddit-stock-sentiment#api (250 req/month free tier).

Fetchers

Model	Description	Example
StockSentiment	Sentiment for a single stock	obb.equity.sentiment("AAPL", source="reddit", provider="adanos")
SentimentTrending	Trending stocks by buzz score	obb.equity.sentiment.trending(source="x", limit=20, provider="adanos")
SentimentCompare	Compare up to 10 stocks	obb.equity.sentiment.compare(symbols="AAPL,TSLA,MSFT", provider="adanos")

Data Fields

Each response includes: buzz_score (0-100), sentiment_score (-1.0 to +1.0), total_mentions, trend (rising/falling/stable), bullish_pct, bearish_pct, and more.

Technical Details

• Built with the standard OpenBB TET (Transform-Extract-Transform) pattern
• Three static Fetcher classes, one HTTP client, no heavy dependencies
• Registered via openbb_provider_extension entry point — auto-discovered on install
• 15 unit tests covering all three fetchers

Why This is Useful

OpenBB currently has limited social sentiment coverage (some via Finnhub). This provider fills the gap with:

• Reddit-native sentiment — VADER + RoBERTa ONNX ensemble, not just keyword counting
• Cross-platform validation — X trending stocks flagged if also trending on Reddit
• Polymarket integration — prediction market odds as a sentiment signal
• Buzz scoring — composite score combining mentions, sentiment, engagement, diversity, and trend

We'd love feedback on the implementation and would be happy to adapt it to better fit the OpenBB ecosystem.

@alexander-schneider, thanks for the share. Are you sure that you have actually installed, compiled, and ran the code? There is nothing in your codebase that would actually generate these endpoints.

I re-tested this locally and you were right to question it.

The old state was not good enough: the extension was registered, but the OpenBB-generated package code was breaking on the router annotations, so the generated obb.adanos.* routes were not actually usable in a clean local install.

I fixed that locally, rebuilt OpenBB, and then verified it against a local Adanos API instance.

What I tested successfully:

• obb.adanos.reddit.health()
• obb.adanos.reddit.trending(days=2, limit=2)

What the screenshot shows:

• the obb.adanos namespace exists
• the generated sub-namespaces are available: news, polymarket, reddit, x
• the OpenBB route metadata is real (/adanos/reddit/health, /adanos/reddit/trending)
• the commands return actual data locally

One small note: on a fresh local dev stack, trending() has no rows by default, so I seeded two sample tickers in the local dev database just to make the end-to-end verification visible.
