# Token Buy-to-Sell Activity Ratio — Named Scenario Comparison

> Token Buy-to-Sell Activity Ratio — Named Scenario Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Compares a baseline token buy/sell count ratio against one or more named alternative scenarios to deterministically assess how ratio changes across each scenario.

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-named-scenario-comparison-4234c98d -d '<json body>'
```

Example prompt: Compare the buy-to-sell ratio for a token with a baseline of 120 buys and 80 sells against two scenarios: one called 'Bull Push' with 200 buys and another called 'Sell Pressure' with 150 sells.

## When to prefer this

Choose this endpoint when you need a deterministic, named comparison of how a token's buy-to-sell ratio shifts across multiple hypothetical scenarios, using supplied observation counts rather than live market data. Prefer it over single-calculation endpoints when evaluating 2–20 labeled alternatives side-by-side in a single call.

## Known failure modes

- sell_count of 0 rejected (exclusiveMinimum enforced)
- scenarios array empty or missing required label/overrides fields
- buy_count or sell_count exceeds maximum bound (10^16)
- overrides object contains no valid properties (minProperties:1 violated)
- scenario label exceeds 80 characters
- payment not fulfilled — x402 payment required before response is returned

## How this service works

Token buy-to-sell activity ratio — Named scenario comparison: Named scenario comparison 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 named scenario comparison report.

## Output

A structured report containing the computed buy-to-sell ratio for the baseline and each named scenario, with deterministic ratio values and optional threshold-based verdicts for each label — not a live market scan or trade recommendation.
