TradeOS VPIN Microstructure Stress

x402

TradeOS VPIN Microstructure Stress is a paid API for AI agents from tradeos.tech, paid per call via x402, $0.12/call, status unknown (last checked 2026-09-15).

Returns VPIN-based order-flow stress metrics and crash-pressure context for use as a pre-trade risk filter in crypto trading systems.

How this service works

Check order-flow and crash-pressure stress before a bot or analyst acts. Returns active stress symbols, stress levels, how fast stress is changing, crash-pressure level, alert level, VPIN flow-risk v2 state, time-to-stress context, and recent VPIN shock incident evidence showing first seen, later low, drawdown, and minutes to low.

Output

A JSON object containing the VPIN score, microstructure stress level, crash-pressure context, order-flow imbalance indicators, reasons/explanations, freshness metadata, and safety boundaries — all ready to plug into a pre-trade risk filter.

Example use cases

Example prompt

“Check the VPIN microstructure stress and crash-pressure context for ETH right now — I need to decide whether to let my trading bot proceed with a large order or hold off.”

Technical details

Endpoint

POSThttps://tradeos.tech/x402/v1/intelligence/tradeos-vpin-stress

When to prefer

Choose this endpoint when you need VPIN-specific order-flow microstructure stress and crash-pressure signals — distinct from general market regime or token risk endpoints — specifically for gating pre-trade decisions in bots or screeners. Prefer it over the bundled intelligence endpoints when VPIN is the only signal needed to minimize cost ($0.12/call) and latency.

Side effects

Unknown or unsupported token symbol returns 404 or empty result
Stale market data causes freshness warning in response
Malformed request body returns 400 validation error
Service unavailable or upstream data feed outage returns 503
Insufficient USDC balance causes x402 payment failure
