How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a market_volatility field containing the volatility assessment or signal, along with any warnings about data quality or scope limitations, an evidence_scope indicating the assessment is based on caller-supplied data, and a full receipt with payment confirmation, execution IDs, latency, and a result hash for verification.
Example use cases
Crypto market volatility check
“Based on this situation — ETH is swinging 8% daily, derivatives open interest is surging, and sentiment is extremely fearful — can you give me a volatility assessment for the current crypto market?”
Pre-trade risk assessment
“Before I execute this large equity position, can you analyze whether the market is in a high-volatility regime given that the VIX just spiked to 35 and there's a Fed announcement tomorrow?”
Portfolio rebalancing decision support
“I'm trying to decide whether to rebalance my portfolio today. Can you assess market volatility given that tech stocks have been swinging 5-7% daily and macro uncertainty is elevated?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/market_volatility/invokeWhen to prefer
Choose this endpoint when you need a quick, pay-per-call volatility signal derived from a natural language or structured description of market conditions, and you are operating in an agent-native, x402-payment-capable environment. Prefer this over traditional financial data APIs when you don't have access to real-time market feeds but can describe market conditions in text, or when you need a lightweight volatility judgment rather than full quantitative modeling.
Side effects
- Empty or too-short input string (below 2 chars) causes validation failure
- Input exceeds 65536 character limit causing rejection
- Malformed JSON request body returns error
- Payment failure via x402 protocol results in 402 response and no computation
- Ambiguous or nonsensical market description may produce low-confidence or warned output
