# Reported Burned Token Fraction — Benchmark Correlation

> Reported Burned Token Fraction — 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 the reported burned token fraction (burned/issued ratio) across a series of observations and a set of benchmark values.

## 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 reported-burned-token-fraction-benchmark-correlation-f7812c25 -d '<json body>'
```

Example prompt: Can you run a benchmark correlation on our token burn fraction? I have 4 observations — burned 100000 out of 2000000 issued, then 110000 out of 2200000, and so on — and I want to correlate that burn fraction against benchmarks of 10, 20, 30, and 40.

## When to prefer this

Use this endpoint when you need a fast, deterministic, cost-effective ($0.01 USDC) statistical correlation between a token's reported burn fraction and a set of benchmark values across multiple observations. It is particularly suited for tokenomics audits, deflationary target tracking, and investor reporting where you supply your own historical data and need a reproducible calculation without a live blockchain scan or trade recommendation.

## Known failure modes

- Fewer than 2 rows provided — minimum of 2 observation rows required
- Fewer than 2 benchmark values provided — minimum of 2 benchmarks required
- issued_tokens value of 0 — exclusiveMinimum constraint prevents division by zero
- More than 200 rows or 200 benchmarks supplied — maxItems exceeded
- burned_tokens or issued_tokens outside allowed numeric range — validation error
- Malformed row objects missing required fields burned_tokens or issued_tokens

## How this service works

Reported burned token fraction — Benchmark correlation: Benchmark correlation for Reported burned token 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 benchmark correlation report.

## Output

Returns a deterministic benchmark correlation report showing how strongly the computed burned token fraction (burned_tokens/issued_tokens ratio) across the supplied observation rows correlates with the provided benchmark series, along with a correlation coefficient and possibly a threshold-based verdict. No live scan or trading recommendation is included.
