How this service works
Get real-time market sentiment signals via x402 M2M API. Signed x402 call. 0.03 USDC on Base.
Output
Returns a JSON object with ok:true, niche 'market_sentiment', a result block containing overall_sentiment (enum: very_bearish, bearish, neutral, bullish, very_bullish), a normalized score in [-1,1], per-component breakdown (Fear & Greed, top-25 24h price momentum ex-stables, DeFiLlama global TVL trend) with individual signal values, and a receipt block containing the Ed25519 signature for verification.
Example use cases
Pre-trade market condition check
“Before my trading bot places its next BTC position, pull the current composite crypto market sentiment — I need the overall_sentiment label, the score, and all three component signals so it can decide whether conditions are favorable.”
Daily DeFi portfolio risk briefing
“Give me today's market sentiment reading across Fear & Greed, top-25 token momentum, and global DeFi TVL trend so I can assess whether to reduce risk exposure in my DeFi portfolio.”
Automated sentiment-gated trade alert
“Check the current market sentiment right now and if the score is below -0.5 (bearish territory), alert me with the full breakdown so I know whether to pause my automated buy orders.”
Technical details
Endpoint
POSThttps://market-sentiment.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need a single signed, deterministic composite crypto market sentiment reading that fuses macro sentiment (Fear & Greed), price momentum (top-25 ex-stables), and DeFi liquidity trend (TVL) into one normalized verdict — ideal for trading bots, risk gates, or portfolio managers that need a low-latency, keyless, verifiable signal without stitching together three separate APIs themselves.
Side effects
- Upstream data source unavailable (Fear & Greed API or DeFiLlama down) — may return error or stale signal
- Payment failure via x402 — 402 response if USDC payment on Base is not completed
- Invalid request format — returns error if POST body is malformed
- Network timeout if any of the three live data sources are slow to respond
