Truth Bear Maritime Chokepoint Passage Chain Gauge
x402
Truth Bear Maritime Chokepoint Passage Chain Gauge is a paid API for AI agents from aeml-x402.zeabur.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).
Returns a 3-leg sequential chain reading for a maritime chokepoint (Hormuz, Suez, Panama, Malacca, etc.) covering sea state vs. operating thresholds, anchorage congestion, and realized daily transits from IMF PortWatch.

How this service works
[3-LEG] Maritime chokepoint passage chain, one chokepoint (?loc=hormuz, suez, panama, malacca and more): leading sea state against operating thresholds -> current anchorage congestion, vessels waiting -> realized realized daily transits from IMF PortWatch (confirmation gate). A sequential chain, not one reading - confidence = how many legs are lit, in order. Sources: IMF PortWatch, NOAA, Open-Meteo. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.
Output
A structured JSON object with a 'legs' field containing keyed readings for each chain leg (sea state, anchorage congestion, realized transits), each with current value, observed_at timestamp, data age in hours, and a record hash. Also includes a cross_line_narrative (descriptive, no forecast), provenance with freshness status, an optional citation block with Ed25519 signature for zero-trust verification, grade/scope disclaimers, and a confidence indicator based on how many legs returned data in order. Returns 422 with no charge if data is unavailable.
Example use cases
Suez Canal shipping delay assessment
“Check the current chokepoint chain for Suez — I need to know if sea conditions are within operating limits, how many vessels are waiting at anchor, and what the actual daily transit count looks like right now.”
Panama Canal drought impact monitoring
“What does the current 3-leg gauge say for the Panama Canal? I want sea state, congestion, and realized transits — and tell me how many legs are lit so I know how confident to be.”
Malacca Strait supply chain risk check
“Run the chokepoint passage chain for Malacca and give me the full reading — operating threshold status, anchorage backlog, and IMF PortWatch transit numbers — I'm assessing supply chain exposure.”

Endpoint
GEThttps://aeml-x402.zeabur.app/gauge/chokepoint-regionWhen to prefer
Choose this endpoint when you need a structured, multi-signal sequential chain for a specific maritime chokepoint combining sea state, congestion, and actual transit throughput in one call. Prefer it over general shipping news or AIS trackers when you want sourced, hash-verified observational data with explicit confidence scoring and provenance trails. Best for supply chain risk monitoring, logistics planning research, or geopolitical trade flow analysis at named chokepoints.
Side effects
- 422 no_charge returned when any required data source is unavailable — no billing occurs
- Partial legs lit: confidence is reduced if one or more legs return no data
- Stale data flagged via freshness field (fresh/recent/stale) in provenance
- Unknown or unsupported chokepoint code in ?loc= parameter may return error or empty legs
- Source outages at IMF PortWatch, NOAA, or Open-Meteo can degrade chain completeness
