# DataSig Carrier Reliability Signal

> DataSig Carrier Reliability Signal is a paid API for AI agents from datasig.ai, paid per call via x402, $1.4/call, status unknown (last checked 2026-09-15).

Returns a live carrier reliability score and booking recommendation signal for a specific carrier and trade lane between two ports.

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 datasig-carrier-reliability-signal-47d95028
```

Example prompt: What's the carrier reliability signal for MSC sailing from CNSHA to DEHAM — should I book with confidence?

## When to prefer this

Use this endpoint when an AI agent or procurement workflow needs a real-time, actionable booking recommendation for a specific carrier on a specific trade lane, rather than generic historical performance data. Prefer this over manual research or static carrier scorecards when decisions must be made quickly and dynamically as market conditions shift. Especially valuable when tariff changes, port congestion, or blank sailing risk make carrier selection time-sensitive.

## Known failure modes

- Missing required query parameters (carrier, origin, or destination) returns a 400 error
- Unknown carrier code returns empty or error response
- Invalid UN/LOCODE for origin or destination may return no data
- Payment failure via x402 micropayment results in 402 and no data returned
- Stale or unavailable signal data may return reduced confidence or partial response

## How this service works

DataSig delivers live supply chain action intelligence to AI agents via x402 micropayments. Tariff changes, port congestion, blank sailing risk, supplier distress. Pay per call in USDC on Base. No API key.

## Output

Returns a JSON object containing a booking action signal (e.g. BOOK_WITH_CONFIDENCE), the carrier code, and a numeric reliability score (0-100) representing current carrier on-time and distress performance on the requested trade lane.
