How this service works
Hourly crypto news-sentiment readings for a ticker (e.g. BTC, ETH), recorded live at the top of every UTC hour and never backfilled. Each row: observed_at, average_compound (-1 to 1), sample_size, Fear & Greed value, matcher and the top 3 headlines behind it (title, link). Query start/end as ISO 8601; default last 7 days, max 30 days per call. See /archive for symbols and coverage.
Output
A JSON object containing the requested symbol, start/end timestamps, total row count, and an array of hourly rows. Each row includes: observed_at (ISO 8601 timestamp), average_compound sentiment score (-1 to 1), sample_size, fear_greed_value (integer), matcher identifier, effective_sample_size, unweighted_compound_72h, newest_headline_age_hours, and a drivers array of up to 5 top headlines with title, source, link, published timestamp, score, weight, and effect fields.
Example use cases
Crypto crash post-mortem analysis
“Show me the hour-by-hour sentiment readings for BTC from 2024-11-01 to 2024-11-07 — I want to see how the compound score and Fear & Greed values moved during that week, and which headlines were driving the swings.”
ETH trading signal research
“Get me the last 7 days of hourly sentiment data for ETH, including the average compound scores and sample sizes, so I can see if sentiment is trending bullish or bearish heading into this weekend.”
Multi-day SOL sentiment dashboard
“Fetch hourly sentiment history for SOL between 2025-03-01T00:00:00Z and 2025-03-30T23:00:00Z — I need the compound sentiment scores, Fear & Greed values, and the top driving headlines for each reading.”
Technical details
Endpoint
GEThttps://crypto-sentiment-x402.onrender.com/history/:symbol?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a time-series of hourly sentiment readings for a specific crypto ticker over a historical window (up to 30 days). It is ideal for trend analysis, backtesting sentiment-based signals, or correlating news sentiment with price action. Prefer this over real-time-only endpoints when you need multiple hours or days of context rather than a single current reading. Note that data is never backfilled, so coverage starts from when the service began logging.
Side effects
- Unsupported ticker symbol — symbol not in /archive coverage returns empty rows or error
- Date range exceeding 30 days returns an error or truncated results
- Invalid ISO 8601 datetime format for start/end causes a 400 error
- No data available for a symbol during the requested window (service only records live, never backfills)
- Payment failure or missing x402 payment header causes 402 Payment Required
- Render.com cold start may cause first-request latency spike or timeout
