## 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 script-master-labs-x402-max-conviction-signal-df060f3f -d '<json body>'
```

Example prompt: What's the max conviction signal for NVDA right now? Pay the $0.25 per-call fee and give me the result.

## When to prefer this

Use this endpoint when you need a pre-computed, high-conviction trading signal for a specific U.S. equity ticker and are willing to pay $0.25 USDC per call via x402 on Base. Prefer this over generic data providers when you want a synthesized signal rather than raw price or fundamental data.

## Known failure modes

- Missing or invalid ticker symbol returns a 400/422 validation error
- Payment failure or insufficient USDC balance causes x402 payment rejection and no data is returned
- Unknown or non-U.S. ticker may return empty or null signal
- Service unavailability on Render infrastructure returns 503
- No output schema defined, so response structure may vary or be undocumented

## 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

A max-conviction trading signal for the requested equity ticker, indicating the strongest data-driven directional recommendation for that stock, delivered after a $0.25 USDC micropayment settled on Base via x402.
