# Token Circulating Supply Fraction — Rolling Mean Report

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

Calculates a rolling mean of the circulating supply fraction (circulating tokens / total tokens) over a sliding window across a series 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-circulating-supply-fraction-rolling-mean-report-f4edbc9a -d '<json body>'
```

Example prompt: Calculate the rolling mean of the circulating supply fraction for these 4 token snapshots — [1,000,000 circulating out of 2,000,000 total], [1,100,000 of 2,200,000], [1,000,000 of 2,000,000], [1,100,000 of 2,200,000] — using a rolling window of 2.

## When to prefer this

Choose this endpoint when you need a deterministic, bounded rolling mean of the token circulating supply fraction across a batch of up to 200 time-series observations. It is purpose-built for tokenomics smoothing use cases and is more appropriate than a generic stats API when you specifically need the circulating/total ratio averaged over a sliding window with preset configuration. At $0.01 USDC per call it is cost-effective for periodic batch analytics pipelines.

## Known failure modes

- Fewer than 2 rows provided — minimum of 2 observation rows required
- Window size larger than number of rows — rolling mean cannot be computed
- total_tokens value of 0 or negative — excluded by schema (exclusiveMinimum: 0)
- circulating_tokens exceeds schema maximum (10^16) — validation error
- More than 200 rows submitted — exceeds maxItems limit
- Missing required fields (circulating_tokens or total_tokens) in any row — schema validation failure
- Payment failure via x402 protocol — request rejected before computation

## How this service works

Token circulating supply fraction — Rolling mean report: Rolling mean report 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 rolling mean report report.

## Output

Returns a rolling mean report of the circulating supply fraction (circulating_tokens / total_tokens) computed over the specified sliding window across all supplied observation rows. The result is a deterministic statistical calculation — not a live scan, safety proof, or trade recommendation.
