# ETH Burn vs Issuance Analysis (EIP-1559)

> ETH Burn vs Issuance Analysis (EIP-1559) is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-15).

Returns ETH burned via EIP-1559 base fees versus estimated validator issuance over the last N blocks, with net supply change, USD value, and daily/yearly extrapolations.

## Facts

- Price: $0.003/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 eth-burn-vs-issuance-analysis-eip-1559-4c3411a1 -d '<json body>'
```

Example prompt: Is Ethereum currently deflationary? Check the last 200 blocks and tell me how much ETH was burned versus issued, whether the supply is shrinking, and what that works out to annually.

## When to prefer this

Use this endpoint when you need a quick, real-time snapshot of Ethereum's burn-vs-issuance dynamics over a recent window of blocks, including deflationary status and extrapolated supply trajectory. Prefer it over manual on-chain queries when you want USD valuation, daily/annual extrapolations, and the deflationary boolean all in one call without running your own Ethereum node.

## Known failure modes

- Invalid blocks value (must be integer 10–1000) returns validation error
- Ethereum node unavailability causes fetch failure
- DefiLlama pricing outage may affect USD conversion accuracy
- Requests with missing required 'blocks' field return schema validation errors

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

A JSON object containing: number of blocks analyzed, data source description, ETH burned, USD value of burn, estimated validator issuance in ETH, net supply change in ETH, whether the period is deflationary (boolean), period duration in minutes, daily extrapolation (net ETH, burned ETH, issuance ETH), and annualized net supply change as a percentage of total supply.
