# Supply Inflation Analyzer

> Supply Inflation Analyzer is a paid API for AI agents from 402.com.tr, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-27).

Measures the real annualized mint/burn rate of a token contract over a configurable time window to detect supply inflation or deflation against its advertised tokenomics.

## 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 supply-inflation-analyzer-97236ade
```

Example prompt: Check the supply inflation rate for the token at 0x1234...abcd on Base over the last 30 days — I want to know if the team is secretly minting and diluting holders.

## When to prefer this

Use this endpoint when you need on-chain evidence of actual supply behavior for a Base token — especially when a project advertises a fixed or capped supply and you want to verify that claim. It is more reliable than reading owner permissions alone (which only show capability, not usage). Prefer this over general token metadata endpoints when the key question is whether holders are being diluted by undisclosed minting.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Days parameter exceeding 45 causes a validation error
- Token with no mint/burn events in the window returns zero activity with a fixed_in_window verdict
- Network or CDP SQL data unavailability may cause a timeout or partial result
- Non-Base-network contract addresses may return no data since analysis is Base-specific

## How this service works

owner-powers says the owner CAN mint; this says whether they ARE, and how fast. A token can advertise fixed supply and quietly inflate it, diluting holders before the dump. Sums zero-address mints and burns over a window (CDP SQL) against live on-chain totalSupply, annualised. Verdict from fixed_in_window / deflationary to hyperinflation. Honest: bridges, staking and LP programs mint legitimately — flags the RATE, not intent. Not financial advice.

## Output

Returns a verdict classifying the token's supply change (e.g. fixed_in_window, deflationary, low inflation, hyperinflation), along with the sum of zero-address mints and burns over the requested window, the current on-chain totalSupply, and the annualized inflation rate as a percentage. Bridges, staking, and LP programs may legitimately cause minting — the endpoint reports the rate without inferring intent.
