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 mycelia-signal-eth-usd-swing-pivot-support-resistance-levels-d394e8b8
```

Example prompt: What are the current ETH/USD swing-pivot support and resistance levels, and how strong and close is price to each of them? I want a cryptographically signed result based on the last 69 days of spot history.

## When to prefer this

Choose this endpoint when you need a cryptographically attested, deterministic view of ETH/USD historical price structure — specifically swing-pivot support and resistance levels — without any forward-looking bias. It is preferable over generic charting APIs when auditability and tamper-evidence matter (e.g., in on-chain logic, agent pipelines requiring signed data, or compliance contexts). It is better than raw OHLC feeds when you need pre-computed strength and proximity metadata rather than doing your own pivot detection.

## Known failure modes

- Payment not received or x402 payment flow incomplete — endpoint returns 402 Payment Required
- Upstream spot price data unavailable — may return 503 or stale attestation
- Ed25519 signature verification fails on client side if public key is not fetched from the discovery endpoint first
- Network timeout if the deterministic computation takes longer than expected
- Invalid or missing request headers may return 400 Bad Request

## How this service works

ETH/USD swing-pivot levels (where price reversed). Deterministic price-structure attestation over 69d spot history — support, resistance, at-level with strength and proximity. Ed25519 signed. No forward-looking claim. — Ed25519 signed attestation

## Output

A deterministic, Ed25519-signed JSON attestation containing ETH/USD swing-pivot price levels identified over a 69-day spot history window, each labeled as support, resistance, or at-level, with an associated strength score (significance of the reversal) and proximity score (distance from current price). No forward-looking price predictions are included.
