# Token Net Supply Flow Before/After Comparison

> Token Net Supply Flow Before/After Comparison 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 and compares token net supply (issued minus burned) for two time snapshots, returning a deterministic before-and-after delta report.

## 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-net-supply-flow-before-after-comparison-93858bb6 -d '<json body>'
```

Example prompt: Compare the token net supply flow for two snapshots: before had 1000 issued tokens and 400 burned, and after had 1100 issued tokens and 440 burned — show me the before-and-after report on how net supply changed.

## When to prefer this

Choose this endpoint when you need a quick, deterministic calculation of how token net supply (issued minus burned) changed between two discrete states — for example after a mint or burn event. It is purpose-built for supply-flow delta reporting on supplied token observations and returns a bounded, reproducible result for $0.01 USDC per call. Prefer it over generic analytics tools when you already have before/after token counts and need a structured comparison report rather than a live on-chain scan or trade signal.

## Known failure modes

- Missing required fields (issued_tokens or burned_tokens in either before or after object) returns a validation error
- Values exceeding the maximum (10^16) may be rejected
- Negative token values are rejected as they fall below the minimum of 0
- Malformed JSON body returns a 400-level error
- Payment failure via x402 protocol prevents execution and returns a 402 response

## How this service works

Token issued less burned supply flow — Before and after comparison: Before and after comparison for Token issued less burned supply flow. 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 before and after comparison report.

## Output

A deterministic before-and-after comparison report showing net supply (issued minus burned) for the 'before' snapshot, net supply for the 'after' snapshot, and the computed delta between the two states. No live market data or trade recommendations are included.
