Signal reference

Every DataSig signal documented. Parameters, action vocabulary, pricing tiers, and example responses. All signals return a named action your agent can act on directly -- not a raw number to interpret.

Tariff and Sourcing Signal

Monitors Federal Register, USTR, and CBP HTS Schedule for tariff changes affecting a specific HTS code and country of origin. Returns an action signal updated continuously from live government data sources.

Blank Sailing Predictor

Status: returns INSUFFICIENT_DATA. No verified carrier schedule source exists yet, so the probability model does not run and every lane gates to INSUFFICIENT_DATA with agent_action: CHECK_CARRIER_DIRECTLY. That response is served free ($0.00) and is never settled. Read the x-datasig-data-quality header on the 402 (available or insufficient) before paying. Everything below describes the model as it will behave once a schedule source is live.

Predicts blank sailing probability for a carrier and trade lane using a 5-factor model: origin congestion (30%), destination congestion (25%), historical blank rate (20%), rate change (15%), and schedule deviation (10%). Incorporates seasonal events including Chinese New Year, Golden Week, and US peak season. Updated every 6 hours across 8 trade lanes. At probability above 0.75, the $5.00 tier fires with a projected cancellation date and cost of inaction.

Common response fields

Every paid signal response includes these fields in addition to signal-specific data:

{
  // Signal-specific fields above, plus:
  "_datasig": {
    "source":     "DataSig",
    "version":    "1.0",
    "signal":     "tariff",
    "signal_hash":"a3f8b2c1...",  // provenance fingerprint
    "live_data":  true,

The _datasig block includes a provenance fingerprint -- a SHA-256 hash of the response payload. The _datasig_pricing block shows your wallet's current discount tier and progress toward the next one.

ILA Labor Sentiment Signal

Monitors NLRB filings, news sentiment, contract status, and strike authorization votes to produce a labor disruption probability score for ILA-covered US East and Gulf Coast ports. At probability above 0.65, the $5.00 tier fires with a projected disruption window, inventory buffer recommendation, cost of inaction per container, and alternative routing options.

Carrier Reliability Signal

Predicts a carrier's on-time performance for a specific trade lane over the next 30 days using a 5-factor scoring model: Sea-Intelligence baseline (30%), AISstream schedule deviation (25%), destination berth congestion (20%), blank sailing probability (15%), and Freightos FBX rate volatility (10%). At score below 50 or blank sailing probability above 0.75, the REBOOK_NOW signal fires with alternative carrier options and cost of inaction.
