How this service works
Classify a signal against optional upper and lower thresholds — call when classifying a signal against upper/lower thresholds. Use on caller-supplied ticks/returns when agents need signal prep without a licensed live market feed (ottoai-class demand, first-party transform). Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web se…
Output
A deterministic JSON object indicating which zone the input value falls into relative to the supplied thresholds — e.g. whether the value is below the lower threshold, above the upper threshold, or within the defined range. No upstream data fetching occurs; the result is computed locally and statelessly from the caller-supplied inputs.
Example use cases
Overbought/oversold signal tagging
“I have an RSI-like value of 72.5 computed from my own tick data — classify it against a lower bound of 30 and an upper bound of 70 so I know if it's overbought, oversold, or neutral.”
Anomaly detection on computed metrics
“My pipeline just produced an error rate of 0.012 — classify that against a lower threshold of 0.001 and upper threshold of 0.01 so I can flag whether it's within normal range or breaching the upper limit.”
Portfolio rebalance trigger check
“Check whether my momentum score of -0.15 breaches either the lower threshold of -0.10 or the upper threshold of 0.10, so I can decide if a rebalance trigger fires.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/signal-thresholdWhen to prefer
Choose this endpoint when you need fast, stateless, deterministic threshold classification of a numeric signal you already have in hand — particularly when you do not have access to a live market data feed and want a cheap ($0.003 USDC) first-party transform with no input retention. Ideal for signal prep pipelines, backtesting logic, or any agent workflow that computes its own tick or return values and needs boundary classification without calling an external data provider.
Side effects
- Missing required 'value' field returns a validation error
- Non-numeric value type causes a schema rejection
- Upper threshold lower than lower threshold may produce unexpected or inverted zone classification
- Payment failure via x402 results in a 402 response before computation occurs
