# Token Drawdown from Supplied Peak — Sequential Input-Change Attribution

> Token Drawdown from Supplied Peak — 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 2026-10-15).

Computes a sequential input-change attribution report for token price drawdown from a user-supplied peak price, comparing before and after scenarios deterministically.

## 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-drawdown-from-supplied-peak-sequential-input-change-attribution-86c95ad0 -d '<json body>'
```

Example prompt: For a token that previously had a peak of $2.00 and current price of $1.50, and now has a peak of $2.20 and current price of $1.65, can you run a sequential input-change attribution on the drawdown to show me what changed between those two scenarios?

## When to prefer this

Choose this endpoint when you need to deterministically compare drawdown from a user-supplied peak across two scenarios (before and after), with sequential attribution identifying which input change (peak price vs current price) drove the difference in drawdown. Prefer this over single-scenario drawdown calculators when you specifically need a before/after comparison with input-level attribution rather than a simple drawdown percentage.

## Known failure modes

- Missing required before or after objects returns a validation error
- current_price equal to or exceeding peak_price may produce zero or negative drawdown values
- Extremely large numbers near the 10^16 boundary may produce precision loss
- Non-numeric values for price fields will be rejected
- Omitting both before and after objects falls back to schema defaults, which may not reflect actual user data

## How this service works

Token drawdown from supplied peak — Sequential input-change attribution: Sequential input-change attribution for Token drawdown from supplied peak. 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 bounded sequential input-change attribution report showing how drawdown from the supplied peak differs between the before and after input scenarios, with deterministic attribution of each input variable's contribution to the change in drawdown. Does not provide live market data, trade recommendations, or safety proofs.
