# Token Buy Volume Fraction — Record Ranking

> Token Buy Volume Fraction — Record Ranking 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).

Ranks a set of token observations by their buy volume fraction (buy volume as a share of total volume) and returns a deterministic record ranking 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-buy-volume-fraction-record-ranking-f2a33d36 -d '<json body>'
```

Example prompt: I have 4 token trading observations — observation 1 had 60,000 buy and 40,000 sell volume, observation 2 had 66,000 buy and 44,000 sell, observation 3 had 60,000 buy and 40,000 sell, and observation 4 had 66,000 buy and 44,000 sell — can you rank them by their buy volume fraction?

## When to prefer this

Choose this endpoint when you have a set of token trading observations (2–200) with explicit buy and sell volume figures and want a deterministic, ranked report of which observations have the highest buy volume fraction. It is not a live scanner or safety checker — prefer it for batch ranking of supplied data rather than real-time market monitoring or trade signal generation.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 observations required
- More than 200 rows supplied — exceeds maxItems limit
- buy_volume or sell_volume is zero or negative — exclusiveMinimum of 0 applies
- buy_volume or sell_volume exceeds 10^16 — out of maximum bounds
- Missing required buy_volume or sell_volume fields in any row object
- Payment of 0.01 USDC not provided or x402 protocol not followed

## How this service works

Token buy volume fraction — Record ranking: Record ranking for Token buy volume 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 record ranking report.

## Output

A bounded record ranking report listing each supplied observation ranked by its buy volume fraction (buy_volume / (buy_volume + sell_volume)). The output is deterministic — given the same inputs, the same ranking is always returned. Does not constitute a trade recommendation or live market scan.
