# Token Circulating Supply Fraction — Before and After Comparison

> Token Circulating Supply Fraction — Before and After Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes and compares the circulating supply fraction of a token between two points in time, returning a deterministic before/after report.

## 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-circulating-supply-fraction-before-and-after-comparison-373b1ea4 -d '<json body>'
```

Example prompt: Compare the circulating supply fraction for a token that had 1,000,000 circulating out of 2,000,000 total before, and now has 1,100,000 circulating out of 2,200,000 total after — give me a before and after breakdown of the supply fraction.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, cost-effective ($0.01 USDC) before/after comparison of circulating supply fraction from two explicit token supply snapshots you already have. Prefer it over general analytics platforms when you want a structured bounded report with no dependency on live blockchain data or external price feeds.

## Known failure modes

- total_tokens set to 0 (excluded by exclusiveMinimum) causes validation failure
- circulating_tokens exceeding total_tokens may produce fraction > 1 without explicit error
- missing required fields (total_tokens or circulating_tokens) in either before or after object causes schema rejection
- values exceeding maximum (10^16) are rejected
- non-numeric inputs are rejected

## How this service works

Token circulating supply fraction — Before and after comparison: Before and after comparison for Token circulating supply 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 before and after comparison report.

## Output

A deterministic before-and-after comparison report containing the circulating supply fraction (circulating tokens / total tokens) for both the 'before' and 'after' snapshots, the absolute and relative change between them, and a bounded verdict based on caller-supplied thresholds. Does not perform live chain scans or provide trade recommendations.
