## 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-fee-demand-pulse-7e95bb63
```

Example prompt: Pull the current ETH fee demand pulse from Edge Agents — I need the confidence level, a summary of findings, and the provenance so I can include it in my strategy report.

## When to prefer this

Choose this endpoint when you need a point-in-time, evidence-bounded, and cryptographically signed snapshot of Ethereum fee demand — especially when your workflow requires provenance, source attribution, or contradiction flagging for audit, compliance, or strategic decision-making. It is preferable over raw blockchain APIs or generic data feeds when you need interpretive analysis with confidence scoring rather than raw numbers, and when you need a disclaimer-compliant research artifact for presentation to boards or regulators.

## Known failure modes

- Payment not received or invalid x402 payment header — returns 402 Payment Required
- Upstream data sources temporarily unavailable — may return incomplete or stale evidence with degraded confidence
- Invalid request format — returns 400 Bad Request
- Service outage — returns 503 with no payload
- Coverage gaps acknowledged in report limitations array when specific evidence is unavailable

## How this service works

Ethereum base-fee and gas-utilisation pulse from point-in-time JSON-RPC evidence with recent fee-history context. Purpose: Measure current execution-layer fee demand using observed base fee and gas utilisation without equating fee pressure with token valuation. 5-minute freshness target; missing evidence is reported explicitly rather than invented.

## Output

A JSON object containing: a quality block with status (e.g. 'strong') and confidence level; an analysis block with asset family ('ethereum'), intent classifications, and a narrative summary of current fee demand findings; an evidence block listing assets covered, policy type, and sources; a signed provenance block; a generatedAt timestamp; schema version; and a disclaimer that this is general market research, not investment advice.
