# Token Rule-Flag Fraction — Sequential Input-Change Attribution

> Token Rule-Flag Fraction — Sequential Input-Change Attribution is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Computes the sequential (waterfall) attribution of changes in a token's rule-flag fraction by comparing before/after flagged-rule and evaluated-rule counts.

## 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-rule-flag-fraction-sequential-input-change-attribution-6a87d4c6 -d '<json body>'
```

Example prompt: Calculate the sequential input-change attribution for a token's rule-flag fraction — before it had 2 flagged rules out of 10 evaluated, and after it has 2.2 flagged rules out of 11 evaluated. Show me the waterfall breakdown of what drove the change.

## When to prefer this

Choose this endpoint when you need a deterministic, auditable waterfall decomposition of exactly how much each input change (flagged_rules vs evaluated_rules) contributed to a shift in a token's rule-flag fraction between two states. Prefer it for compliance audits, rule-tuning analyses, or any scenario where you need a structured before/after attribution rather than a raw ratio difference.

## Known failure modes

- evaluated_rules set to 0 (excluded by exclusiveMinimum constraint) causes validation error
- flagged_rules or evaluated_rules out of allowed numeric range
- missing required before or after fields returns schema validation error
- network or payment authorization failure for the $0.01 USDC x402 charge

## How this service works

Token supplied rule-flag fraction — Sequential input-change attribution: Sequential input-change attribution 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 sequential input-change attribution report.

## Output

A deterministic sequential (waterfall) attribution report showing how changes in the before/after flagged_rules and evaluated_rules inputs each contributed to the overall change in the token rule-flag fraction. Not a live scan or safety proof — results are based purely on the supplied numbers.
