## 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 scriptmasterlabs-cascade-signal-api-be408965 -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need a cascade signal specifically for equity tickers and are able to pay $0.001 USDC per call via x402 on Base or via sovereign X-PAYMENT-TX on Robinhood Chain. Prefer this over generic financial data APIs when your workflow requires crypto micropayment-gated, per-call access without a traditional API subscription, or when integrating with x402-aware agent pipelines.

## Known failure modes

- 402 Payment Required — if no valid x402 payment or API key is provided, the endpoint returns HTTP 402 and the request is rejected
- Invalid or missing ticker symbol — empty or malformed symbol field may return an error or empty result
- Unknown ticker — unrecognized equity symbols may return no signal data
- Service unavailability — hosted on Render free tier, cold starts may cause timeouts
- Expired or insufficient payment — if USDC payment on Base or USDG on Robinhood Chain is not processed, access is denied

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output
