# TruthBear Land Border Wait Chain – Single Crossing

> TruthBear Land Border Wait Chain – Single Crossing is a paid API for AI agents from api.truthbear.co, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).

Returns a 3-leg sequential signal chain (upstream pressure → current CBP wait times → realized freight delay) for a single monitored US land border crossing.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability truthbear-land-border-wait-chain-single-crossing-29689566
```

Example prompt: What does the full border wait chain look like for the Laredo World Trade crossing right now — show me the upstream pressure, current CBP wait times, and any realized freight delay, and tell me how many legs are lit?

## When to prefer this

Use this endpoint when you need a real-time, multi-signal view of a specific US land border crossing for commercial freight — combining upstream traffic pressure, live CBP lane wait times, and realized delay confirmation into one confidence-scored chain. Prefer this over raw CBP data sources when you want a structured, normalized chain signal with a confidence indicator rather than a single raw reading. Use sibling endpoint gauge/history-series for historical trend exports, or gauge/calibrated for cross-station normalized comparisons.

## Known failure modes

- 422 no_charge returned when no data is available for the requested entity — not billed
- Invalid or unrecognized entity ID returns an error; valid IDs can be fetched from GET /gauge/catalog
- Missing required 'entity' query parameter causes request failure
- Partial chain confidence if only some legs have live data (e.g. only leg 1 and 2 lit, leg 3 dark)

## How this service works

[3-LEG] Land border chain, one crossing (?entity=laredo-world-trade): leading upstream pressure - lead traffic, staffing and inspection intensity -> current current CBP border wait times by lane -> realized commercial freight delay (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: US CBP. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.

## Output

A sequential 3-leg chain result: (1) leading upstream pressure signal (lead traffic, staffing, and inspection intensity), (2) current CBP border wait times broken down by lane type, and (3) realized commercial freight delay confirmation. Each leg has a lit/unlit status; overall confidence equals the number of legs lit in order. Returns 422 with no charge if no data is available.
