# Supplied Tiered-Weight Shipping Charge - Adjacent Period Changes

> Supplied Tiered-Weight Shipping Charge - Adjacent Period Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Computes adjacent period-over-period changes in tiered-weight shipping charges given base charge, parcel weight, included weight, and extra-weight rate inputs (up to 200 records).

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 supplied-tiered-weight-shipping-charge-adjacent-period-changes-baa03e0b -d '<json body>'
```

Example prompt: Compare shipping charge changes between two adjacent periods for these records: first period has base charge $5, parcel weight 7 lbs, included weight 2 lbs, extra weight rate $1.50; second period has base charge $5.50, parcel weight 7.7 lbs, included weight 2.2 lbs, extra weight rate $1.65.

## When to prefer this

Choose this endpoint when you need to compute period-over-period changes in tiered-weight shipping charges using retail-supplied figures (base charge, parcel weight, included weight, extra weight rate) in batch up to 200 records. Prefer this over general shipping calculators when the specific requirement is adjacent period delta analysis for tiered weight pricing structures rather than a single point-in-time rate lookup or live carrier rate retrieval.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 records required for adjacent period comparison
- More than 200 rows submitted — maxItems limit exceeded, request rejected
- Invalid field types (non-numeric values for charge or weight fields) cause validation errors
- Negative values rejected — all fields require minimum 0
- Missing required fields (base_charge, parcel_weight, included_weight, extra_weight_rate) cause schema validation failure
- Payment not fulfilled via x402 protocol — endpoint returns 402 Payment Required

## How this service works

Supplied tiered-weight shipping charge - Adjacent period changes: Adjacent period changes for Supplied tiered-weight shipping charge. Supplied retail figures only, up to 200 records. No platform access, live rates or order execution. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded adjacent period changes report.

## Output

Returns a bounded report of adjacent period changes for the supplied tiered-weight shipping charge records, showing computed deltas between consecutive rows (up to 200 records).
