Pass two metric_ids (typically same factor at different windows, e.g. VOL_RV_7D vs VOL_RV_30D) and a threshold. Fires on the delta z(a) − z(b). Same institutional envelope. Applies across every factor family: TR, VOL, FLOW, FUT, OB, CORR. Backtests run over the CRYPTYX 200+ tracked digital assets — BTC, ETH, SOL, top-cap + long-tail coverage.","url":"https://cryptyx.ai/api/triggers/z-differential?utm_source=zero.xyz","method":"GET","headers":{},"bodySchema":{"type":"object","$schema":"https://json-schema.org/draft/2020-12/schema","required":["input"],"properties":{"input":{"type":"object","required":["type","method"],"properties":{"type":{"type":"string","const":"http"},"method":{"enum":["GET"],"type":"string"},"queryParams":{"type":"object","required":["asset","metric_a_id","metric_b_id","operator","threshold"],"properties":{"asset":{"type":"string","description":"Asset symbol (uppercased server-side)."},"horizon":{"type":"string","description":"'7d', '14d' (default), or '30d'."},"operator":{"type":"string","description":"One of 'gt', 'lt', 'gte', 'lte', 'abs_gt'."},"threshold":{"type":"number","description":"Threshold on z(a) − z(b). e.g. 1.0 for a one-sigma differential."},"metric_a_id":{"type":"string","description":"First metric ID (short window), e.g. 'VOL_RV_7D'."},"metric_b_id":{"type":"string","description":"Second metric ID (long window), e.g. 'VOL_RV_30D'."}}}},"additionalProperties":false},"output":{"type":"object","required":["type"],"properties":{"type":{"type":"string"},"example":{"type":"object"}}}}},"responseSchema":null,"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.05","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.05/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.05","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.05","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_asj6ZLHWKH2ZYyBNUcnj_","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.05","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Fires a trigger signal when the z-score differential between two metrics (e.g. short-window vs long-window realized volatility) crosses a user-defined threshold for a given crypto asset.","exampleAgentPrompt":"Check CRYPTYX for BTC — fire a trigger if the z-score of VOL_RV_7D minus the z-score of VOL_RV_30D is greater than 1.5 over a 14-day horizon.","exampleUseCases":[{"title":"Volatility regime crossover alert for BTC","prompt":"Tell me if BTC is in a short-term volatility spike — fire the CRYPTYX z-differential trigger when the 7-day realized vol z-score exceeds the 30-day realized vol z-score by more than 1 sigma over a 14-day horizon."},{"title":"ETH flow factor divergence detection","prompt":"Check CRYPTYX for ETH: trigger a signal if the z-score of FLOW_7D minus the z-score of FLOW_30D is above 2.0, using operator 'gt' and a 30-day horizon."},{"title":"Altcoin momentum crossover screening","prompt":"For SOL, use the CRYPTYX z-differential trigger to check if the short-window momentum factor z-score has crossed below the long-window z-score by more than 1.2 — use 'lt' operator with a 14-day horizon."}],"resultDescription":"Returns whether the trigger fired (true/false) based on whether z(metric_a) − z(metric_b) satisfies the operator and threshold condition for the specified asset and horizon, along with the computed differential value and context metadata.","failureModes":["Invalid or unrecognized metric_id returns an error indicating the metric is not tracked","Unsupported asset symbol results in a 400-level error","Invalid operator string (not in allowed enum) causes a validation error","Threshold not a number causes schema validation failure","Horizon value outside allowed set ('7d','14d','30d') returns an error","Insufficient historical data for a long-tail asset may result in a null or low-confidence trigger result"],"whenToPreferThis":"Use this endpoint when you need to detect crossover or divergence events between two CRYPTYX factor metrics at different windows for a specific digital asset — especially for volatility, flow, order book, correlation, or futures factor families.
