# Token Sell Proceeds Shortfall — Sequential Input-Change Attribution

> Token Sell Proceeds Shortfall — Sequential Input-Change Attribution 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).

Computes a sequential (waterfall) attribution of the shortfall between expected and actual token sell proceeds across a before/after scenario 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-sell-proceeds-shortfall-sequential-input-change-attribution-73545e44 -d '<json body>'
```

Example prompt: I sold tokens and expected $110 but only got $103.40 — previously I expected $100 and got $94. Can you run a sequential input-change attribution to break down how the shortfall changed between those two scenarios?

## When to prefer this

Choose this endpoint when you need a deterministic, structured waterfall decomposition of how input changes (expected vs actual proceeds) drove a shift in token sell shortfall between two observation points. Prefer this over generic financial analytics when you have explicit before/after USD proceeds pairs and need a sequential attribution rather than a summary difference or live market data.

## Known failure modes

- expected_usd must be greater than 0 (exclusiveMinimum); zero value will be rejected
- actual_usd or expected_usd exceeding 1e16 will be rejected by schema
- Missing required fields (expected_usd or actual_usd in before/after) will cause a validation error
- Non-numeric values for any proceeds field will fail schema validation
- Payment not included or insufficient USDC will result in 402 payment required response

## How this service works

Token sell proceeds shortfall — Sequential input-change attribution: Sequential input-change attribution 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 sequential input-change attribution report.

## Output

A deterministic, bounded sequential input-change attribution report showing how changes in the expected and actual USD proceeds inputs contributed to the shift in token sell proceeds shortfall between the before and after scenarios. Output is a structured breakdown (waterfall) of each input's contribution to the delta, not a live market scan or trade recommendation.
