## 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-sol-usd-support-resistance-levels-8116d609
```

Example prompt: What are the current SOL/USD support and resistance levels right now — with strength and proximity scores — using the 69-day historical analysis from Mycelia Signal?

## When to prefer this

Use this endpoint when you need a deterministic, cryptographically verifiable attestation of SOL/USD price structure levels — particularly when cross-method corroboration (pivot + density + round number) is required for confidence, or when you need an Ed25519-signed result for auditability or on-chain use. Prefer over generic TA APIs when you need multi-method agreement, signed outputs, or structured proximity/strength metadata rather than raw charting data.

## Known failure modes

- Payment not included or invalid x402 USDC payment — returns 402 Payment Required
- Upstream price data unavailable — may return 503 or stale data error
- Signature verification failure on client side if public key mismatch
- Rate limiting if called too frequently without proper payment flow

## How this service works

SOL/USD union of pivot+density+round with cross-method corroboration. 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 SOL/USD support and resistance price levels derived from 69 days of spot history, with each level tagged by type (support/resistance/at-level), strength score, proximity to current price, and the corroboration method (pivot, density, round number). No forward-looking or predictive claims are made.
