> Token Trade Depth — Target Gap Calculator is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Calculates the target gap between a token trade size and quoted liquidity depth, returning a deterministic verdict based on supplied trade and liquidity 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 token-trade-depth-target-gap-calculator-c9a56c3f -d '<json body>'
```

Example prompt: Can you calculate the target gap for a token trade of $5,000 against a quoted liquidity of $200,000, using a target threshold of 50?

## When to prefer this

Choose this endpoint when you need a fast, deterministic calculation of the gap between a token trade size and available quoted liquidity against a caller-defined target threshold — particularly useful for pre-trade checks, bot trade sizing validation, or liquidity adequacy assessment without needing live market data feeds or safety oracles.

## Known failure modes

- Missing required values (trade_usd or liquidity_usd) returns a validation error
- Zero or negative trade_usd or liquidity_usd rejected due to exclusiveMinimum constraint
- Values exceeding maximum bounds (1e16) return an out-of-range error
- Invalid JSON body returns a 400-level error
- Payment not included or insufficient results in 402 Payment Required

## How this service works

Token trade relative to quoted liquidity — Target gap calculation: Target gap calculation for Token trade relative to quoted liquidity. 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 target gap calculation report.

## Output

A bounded target gap calculation report indicating the computed gap between the trade size and quoted liquidity relative to the specified target, returning a deterministic verdict (e.g., within/outside threshold) based solely on the supplied input values — not a live scan or trade recommendation.
