How this service works
Crypto Market Data Integrity Attestation for agents and trading systems. Validate caller-supplied crypto market observations for causal timing, freshness, gaps, sequencing, identity consistency, and cryptographic record hashes. Returns deterministic PASS/FAIL, safe_to_use, named checks, and attestation identity. Use before analytics, research, or trading workflows. No market data acquisition or redistribution; no trade recommendation.
Output
Returns a deterministic PASS or FAIL verdict, a safe_to_use boolean, individual named check results (e.g. freshness, receive lag, sequencing, identity consistency, hash verification), and an attestation identity for auditability. No market data is redistributed or acquired.
Example use cases
Pre-trade data freshness check
“Before placing any trades, validate my ETH/USDT order book observations from dataset 'ethusdt-live' — require them to be no older than 3000ms, max receive lag 1500ms, sequencing enforced, identity consistency on, and clock skew up to 250ms. Tell me if it's safe to use.”
Analytics pipeline data quality gate
“I'm about to kick off a crypto market analytics run on dataset 'multi-asset-2024-q1'. Attest these 50 observations for freshness (max age 60000ms), receive lag under 5000ms, expected interval of 1000ms with 200ms tolerance, and flag any identity inconsistencies or hash mismatches.”
Detect sequencing gaps in live feed
“Can you check my crypto market data feed 'coinbase-btc-feed' for any sequence gaps or out-of-order events? Use a policy with max age 10000ms, max receive lag 3000ms, require sequence enabled, identity consistency required, and allowed future clock skew of 500ms.”
Technical details
Endpoint
POSThttps://api.tradebot.devs.surf/v1/market-data-attestation?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, auditable integrity check on caller-supplied crypto market data before downstream analytics, research, or trading workflows — especially when you need named, per-check results for causal timing, freshness, sequencing, and cryptographic hash verification. Prefer this over generic data validators when working specifically with time-series financial market observations that require strict sequencing and identity consistency guarantees.
Side effects
- FAIL returned when any observation exceeds max_age_ms or max_receive_lag_ms thresholds
- FAIL on sequence gaps or out-of-order sequence numbers when require_sequence is true
- FAIL on identity label inconsistencies when require_identity_consistency is true
- FAIL on payload_sha256 mismatch if hashes are supplied
- FAIL when event_time_ms is in the future beyond allowed_future_clock_skew_ms
- Invalid input schema (missing required fields like event_time_ms or received_time_ms) returns a 4xx error
- Exceeding 512 observations per request results in a validation error
