# Token Bid-Ask Spread One-Input Sensitivity Table

> Token Bid-Ask Spread One-Input Sensitivity Table 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).

Computes a one-input sensitivity table for token bid-ask spread by varying either the ask or bid price across a set of values against a baseline quote pair.

## 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-one-input-sensitivity-table-97a017d4 -d '<json body>'
```

Example prompt: Run a one-input sensitivity table on the ask side of a token's bid-ask spread, with a baseline of ask=1.02 and bid=0.98, and test ask values of 0.90, 1.00, 1.05, 1.10, and 1.20.

## When to prefer this

Choose this endpoint when you need a fast, deterministic sensitivity analysis of token bid-ask spread across a range of ask or bid prices relative to a known baseline, without requiring live market feed data. It is ideal for pre-trade analysis, threshold-based verdict generation, or batch scenario modeling within a bounded range of up to 50 price points.

## Known failure modes

- Invalid field value (not 'ask' or 'bid') returns validation error
- Values array empty or exceeds 50 items returns schema error
- Baseline ask or bid price is zero or negative (exclusiveMinimum:0 violated) returns validation error
- Values outside the allowed numeric range return validation errors
- Malformed JSON body returns 400-level error

## How this service works

Token bid-ask spread — One-input sensitivity table: One-input sensitivity table 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 one-input sensitivity table report.

## Output

Returns a structured one-input sensitivity table showing computed bid-ask spread values for each supplied price input (ask or bid), evaluated against the provided baseline quote pair. Results are deterministic calculations based on caller-supplied token observations, not live market data or trade recommendations.
