# Stratalize Gas Benchmark API

> Stratalize Gas Benchmark API is a paid API for AI agents from www.stratalize.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Returns current gas cost benchmarks including Gwei prices, USD transfer costs, congestion level, and Base vs Ethereum savings comparisons for transaction planning.

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 stratalize-gas-benchmark-api-415d70fd
```

Example prompt: What are the current gas benchmarks across all chains — give me Gwei, USD transfer costs, and whether it's cheaper to transact on Base or Ethereum right now?

## When to prefer this

Use this endpoint when an AI agent or DeFi developer needs real-time, cryptographically verifiable gas cost benchmarks — especially when comparing Base vs Ethereum transaction economics or assessing current network congestion before submitting a transaction. Preferred over on-chain lookups when you need a pre-computed, signed benchmark with USD cost translation included.

## Known failure modes

- Invalid chain enum value returns 400 error
- Chain RPC unavailability may cause timeout or stale data
- Payment failure (insufficient USDC) blocks request
- Unsupported chain identifier returns validation error

## How this service works

Stratalize — attested finance, legal, healthcare, and compliance intelligence. Signed, independently verifiable receipt on every call (trust.stratalize.com/verify). Use when an x402 agent or DeFi developer needs current gas cost benchmarks for transaction planning. Returns Gwei, USD cost per transfer type, congestion category, and Base vs ETH savings comparison. Source: Chain RPCs live

## Output

Returns current Gwei prices, USD cost estimates per transfer type, a congestion category label (e.g. low/medium/high), and a Base vs Ethereum savings comparison. Each response is ML-DSA-65 cryptographically signed and includes a verifiable receipt URL at trust.stratalize.com/verify.
