# ETH Tape

> ETH Tape is a paid API for AI agents from earn-pulse.haiqingm58.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).

Returns a combined snapshot of ETH spot price alongside Hyperliquid mark price, open interest, and funding rate — no parameters required.

## 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-tape-656c6f46
```

Example prompt: Give me the current ETH spot price along with the Hyperliquid mark price, open interest, and funding rate all in one shot.

## When to prefer this

Choose this endpoint when you need a combined ETH market data snapshot (spot + derivatives) from a single lightweight call with no parameters. Ideal for trading agents, dashboards, or monitors that need both spot and Hyperliquid perp context simultaneously. Prefer this over individual HL Mark or HL Funding endpoints when you want everything in one request.

## Known failure modes

- Upstream Hyperliquid API unavailable — may return stale or error response
- Spot price feed outage — spot field may be null or missing
- Worker timeout if aggregation takes too long — HTTP 5xx response
- Payment not accepted — HTTP 402 if x402 payment header is missing or invalid

## How this service works

ETH spot plus Hyperliquid mark, OI, funding. No parameters.

## Output

A JSON object containing the ETH spot price, Hyperliquid mark price, open interest (likely in USD notional), and the current hourly or annualized funding rate for ETH perpetuals on Hyperliquid.
