# Token Sell Proceeds Shortfall — Target Gap Calculator

> Token Sell Proceeds Shortfall — 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 gap between expected and actual USD proceeds from a token sell, determining how far short the outcome fell from a target threshold.

## 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-sell-proceeds-shortfall-target-gap-calculator-7d5c61c3 -d '<json body>'
```

Example prompt: I sold some tokens and expected $100 USD but only got $94 USD — can you calculate the shortfall gap against my target of $100 and tell me how far short I fell?

## When to prefer this

Use this endpoint when you need a fast, deterministic computation of the USD gap between expected and actual token sell proceeds against a numeric target — especially inside automated trading workflows, post-sale reconciliation pipelines, or agent-driven portfolio audits where a structured shortfall verdict is needed without triggering a live market scan or trade signal.

## Known failure modes

- Missing required fields (expected_usd or actual_usd) returns a validation error
- expected_usd must be greater than 0 (exclusiveMinimum enforced)
- Values exceeding maximum bounds (10^16 for USD fields, 10^18 for target) may be rejected
- Non-numeric inputs cause schema validation failure
- Payment failure (insufficient USDC) results in 402 response before calculation runs

## How this service works

Token sell proceeds shortfall — Target gap calculation: Target gap calculation for Token sell proceeds shortfall. 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

Returns a bounded target gap calculation report indicating the numerical shortfall between expected and actual USD token sell proceeds, relative to the specified target threshold. The result is deterministic — not a live market scan or trade recommendation.
