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 sitecheck-trade-energy-mississippi-barge-rates-6cc3f099
```

Example prompt: Pull the last 8 weeks of downbound grain barge rates on the Upper Mississippi — I want to see the Cincinnati, St. Louis, and Cairo-Memphis figures from the USDA BTS dataset.

## When to prefer this

Use this endpoint when you need structured weekly grain barge rate data for the Upper Mississippi River segmented by key port locations (Cincinnati, St. Louis, Cairo-Memphis) from the official USDA/BTS dataset. Ideal for logistics cost analysis, agricultural supply chain research, or historical freight benchmarking through November 2023. Not suitable if you need real-time or post-November-2023 barge rates, draft data, or lock-status information.

## Known failure modes

- Dataset is static and ends November 2023 — no data beyond that date will be returned
- Units are not stated in the source dataset, so numeric values may require domain knowledge to interpret
- Requesting more weeks than available in the dataset will return only available rows
- Invalid 'weeks' parameter values outside 1–52 may produce errors or unexpected results
- Upstream BTS data source unavailability may cause stale or failed responses

## How this service works

Pay-per-call logistics, shipping, trade and energy data tools for AI agents, from official and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger.

## Output

A JSON object containing an array of weekly rows, each with a week date, Cincinnati rate, St. Louis rate, Cairo-Memphis rate, and two additional rate columns (rate and rate1/rate3).
