# Token Supplied Rule-Flag Fraction — Adjacent Period Changes

> Token Supplied Rule-Flag Fraction — 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 how the fraction of flagged rules among evaluated rules changes between adjacent time periods for a set of token observations.

## 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 token-supplied-rule-flag-fraction-adjacent-period-changes-4b3dec4e -d '<json body>'
```

Example prompt: Can you calculate the adjacent period changes in rule-flag fraction for these token observations: period 1 had 2 flagged out of 10 evaluated rules, period 2 had 2.2 flagged out of 11 evaluated, period 3 had 2 flagged out of 10, and period 4 had 2.2 flagged out of 11?

## When to prefer this

Choose this endpoint when you need a deterministic, period-over-period delta of the rule-flag fraction from a fixed set of token observations (up to 200 rows). It is ideal for compliance audits, drift detection, or batch reporting where a bounded calculation is sufficient and no real-time scanning or live market data is required.

## Known failure modes

- Fewer than 2 rows submitted — minimum array length not met
- evaluated_rules value of 0 — division by zero excluded via exclusiveMinimum constraint
- Row count exceeds 200 items — maxItems limit breached
- Missing required fields flagged_rules or evaluated_rules in any row — validation error
- Values outside allowed numeric range cause rejection

## How this service works

Token supplied rule-flag fraction — Adjacent period changes: Adjacent period changes for Token supplied rule-flag fraction. Supplied token observations only. Deterministic calculation or caller-threshold verdict, not a live scan, safety proof or trade recommendation. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded adjacent period changes report.

## Output

Returns a bounded report of adjacent period changes in the flagged-rule fraction (flagged_rules / evaluated_rules) across the submitted observation rows, showing how the ratio shifts between consecutive data points. The calculation is deterministic and does not constitute a live scan, safety proof, or trade recommendation.
