# Token Bid-Ask Spread Target Gap Calculator

> Token Bid-Ask Spread 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 2026-10-13).

Calculates the target gap for a token's bid-ask spread given observed bid/ask prices and a target value, returning a deterministic 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-bid-ask-spread-target-gap-calculator-41235a54 -d '<json body>'
```

Example prompt: Calculate the bid-ask spread target gap for a token with a bid price of 0.98 and ask price of 1.02, using a target of 100.

## When to prefer this

Use this endpoint when you need a fast, cheap, deterministic calculation of the bid-ask spread target gap for a token given specific observed bid and ask prices, especially when you already have the price observations and just need the gap computed against a threshold — not for live market scanning, price discovery, or safety analysis.

## Known failure modes

- bid or ask price is zero or negative — rejected by schema minimum constraint
- ask price lower than bid price — may produce unexpected or inverted gap result
- target value outside supported range — capped at schema maximum
- missing required bid or ask values — request rejected with validation error
- payment not included or insufficient — 402 payment required response

## How this service works

Token bid-ask spread — Target gap calculation: Target gap calculation for Token bid-ask spread. 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 deterministic target gap calculation report for the token's bid-ask spread, indicating the computed gap relative to the supplied target value and optionally a threshold verdict — no live market data or trade recommendations included.
