# Checkout Payment Failure Share – Base-100 Rebase Report

> Checkout Payment Failure Share – Base-100 Rebase Report is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Computes a Base-100 rebased index of checkout payment failure share from supplied retail payment attempt data (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 checkout-payment-failure-share-base-100-rebase-report-8285cfa3 -d '<json body>'
```

Example prompt: I have 4 rows of checkout payment data — row 1: 100 attempts, 4 failures; row 2: 110 attempts, 4.4 failures; row 3: 95 attempts, 5 failures; row 4: 120 attempts, 6 failures — can you rebase the payment failure share to a Base-100 index using row 0 as the base?

## When to prefer this

Choose this endpoint when you have raw retail checkout payment attempt and failure count data and need it normalized to a Base-100 index for trend analysis, benchmarking, or comparison — without requiring live payment gateway access, platform integration, or order execution. Ideal for offline analytics, report generation, or agent-driven data pipelines processing up to 200 periods of retail data.

## Known failure modes

- Fewer than 2 rows supplied — minimum rows requirement not met
- base_index out of range — must be between 0 and (number of rows - 1)
- payment_attempts is zero for any row — causes division-by-zero in failure share calculation
- More than 200 rows supplied — exceeds maxItems limit
- Non-numeric or missing failed_attempts or payment_attempts values
- Payment fails or USDC balance insufficient for the $0.01 per-call fee

## How this service works

Checkout payment failure share - Base-100 rebase report: Base-100 rebase report for Checkout payment failure share. 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 base-100 rebase report report.

## Output

A Base-100 rebased series representing the checkout payment failure share for each supplied row, normalized relative to the specified base_index row. The output shows how failure share moves relative to the baseline (set to 100), enabling period-over-period or scenario-over-scenario comparison of checkout payment failure rates.
