# Token Circulating Supply Fraction — Sequential Input-Change Attribution

> Token Circulating Supply Fraction — 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 2026-10-12).

Computes a sequential input-change attribution (waterfall) report for the token circulating supply fraction metric, given before and after token supply observations.

## 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-circulating-supply-fraction-sequential-input-change-attribution-a3bf3850 -d '<json body>'
```

Example prompt: I had 1,000,000 circulating tokens out of 2,000,000 total before, and now I have 1,100,000 circulating out of 2,200,000 total — can you run a sequential input-change attribution on the circulating supply fraction to show how each input change contributed to the shift?

## When to prefer this

Choose this endpoint when you need to deterministically decompose why a token's circulating supply fraction changed between two points in time, attributing each input variable's contribution sequentially. Prefer it over a simple before/after comparison when you need a waterfall-style breakdown showing the marginal contribution of circulating_tokens vs total_tokens changes. Not suitable for live price data, safety audits, or trade signals.

## Known failure modes

- Missing required fields (circulating_tokens or total_tokens in before/after objects) returns a validation error
- total_tokens of zero or negative triggers exclusiveMinimum constraint violation
- Values exceeding 10^16 maximum boundary are rejected
- Malformed JSON body returns 400-level error
- Payment not included or insufficient USDC results in 402 Payment Required

## How this service works

Token circulating supply fraction — Sequential input-change attribution: Sequential input-change attribution for Token circulating supply fraction. 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 sequential input-change attribution (waterfall) report for the token circulating supply fraction, showing how changes in each input (circulating_tokens and total_tokens) sequentially contributed to the overall change in the fraction. Includes a bounded attribution breakdown, before and after fraction values, and optionally a caller-threshold verdict. No live market data, no safety proof, no trade recommendation.
