# Token Buy-to-Sell Activity Ratio — Benchmark Correlation

> Token Buy-to-Sell Activity Ratio — Benchmark Correlation 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 the correlation between a token's buy-to-sell activity ratio time series and a supplied benchmark series, returning a deterministic bounded report.

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-buy-to-sell-activity-ratio-benchmark-correlation-bc759dd6 -d '<json body>'
```

Example prompt: I have 4 periods of token trading data — buys of 120, 132, 120, 132 and sells of 80, 88, 80, 88 — and I want to know how closely the resulting buy-to-sell ratio correlates with benchmark values of 10, 20, 30, 40.

## When to prefer this

Choose this endpoint when you need a fast, deterministic correlation score between a token's buy-to-sell pressure ratio and a custom numeric benchmark series, especially when you already have structured buy/sell count observations and a reference signal. Prefer it over generic statistics APIs when the domain is specifically token trading activity ratios and you want a preset, bounded report at low cost ($0.01 USDC per call).

## Known failure modes

- Fewer than 2 rows or benchmark values supplied — minimum items constraint violated
- Mismatched array lengths between rows and benchmarks may produce undefined or degenerate correlation
- sell_count of exactly 0 rejected due to exclusiveMinimum constraint, causing validation error
- More than 200 rows or benchmark items supplied — maxItems constraint exceeded
- Non-numeric values in buy_count, sell_count, or benchmarks fields cause schema validation failure

## How this service works

Token buy-to-sell activity ratio — Benchmark correlation: Benchmark correlation for Token buy-to-sell activity ratio. 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 benchmark correlation report.

## Output

A bounded benchmark correlation report containing the computed correlation coefficient(s) between the derived buy-to-sell ratio series and the supplied benchmark values, produced via a deterministic calculation — not a live scan or trade recommendation.
