# Token Circulating Market Value — Base-100 Rebase Report

> Token Circulating Market Value — 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 2026-10-13).

Computes a Base-100 rebased index series for token circulating market capitalization (price × circulating supply) across a supplied sequence of observations, anchored to a chosen base period.

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 token-circulating-market-value-base-100-rebase-report-b618fee0 -d '<json body>'
```

Example prompt: Take these 4 token snapshots — prices $2.00, $2.20, $2.00, $2.20 with circulating supplies 1,000,000, 1,100,000, 1,000,000, 1,100,000 — and give me a Base-100 rebase report for the circulating market cap, anchored to the first observation.

## When to prefer this

Choose this endpoint when you need a deterministic, normalized Base-100 index of token circulating market cap (price × supply) over a supplied historical or hypothetical series, particularly for charting relative growth, building investor reports, or comparing market cap trajectories across different periods. It is not a live market data feed, safety scanner, or trade signal — use it when you already have the raw price and supply observations and need them rebased to a reference point.

## Known failure modes

- Fewer than 2 rows supplied — API returns validation error
- base_index out of range (≥ number of rows supplied) — returns error
- price_usd or circulating_tokens ≤ 0 or missing — schema validation failure
- More than 200 rows submitted — exceeds maxItems limit
- Non-numeric values in price_usd or circulating_tokens fields — parse error
- Payment not settled (x402 protocol) — 402 Payment Required response

## How this service works

Token circulating market value — Base-100 rebase report: Base-100 rebase report for Token circulating market value. 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 base-100 rebase report report.

## Output

Returns a deterministic Base-100 rebase report: each input row's circulating market cap (price_usd × circulating_tokens) is expressed as an index value relative to the chosen base observation (set to 100), so a value of 150 means market cap is 50% higher than at the base period. Output includes the indexed series for all supplied rows.
