## 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 sml-sovereign-signal-triple-lock-per-symbol-signal-lookup-a4d16523
```

Example prompt: Get me the SML Sovereign Signal Triple Lock for BTC — I'm okay paying the per-call fee.

## When to prefer this

Choose this endpoint when you need ScriptMasterLabs' proprietary 'Triple Lock' signal for a specific ticker and are willing to pay $0.05 USDC per call via the x402 protocol. Prefer this over generic market data APIs when you specifically want SML's sovereign signal product with its built-in provider verification and proof-of-delivery mechanism.

## Known failure modes

- Payment not submitted or rejected — 402 response with payment terms returned instead of signal data
- Invalid or unrecognized ticker symbol — may return empty or error response
- Payment accepted but delivery proof not confirmed — signal may not be released
- Network or provider availability issues — timeout or 5xx error
- Malformed symbol in URL path — 400 bad request

## How this service works

Pay-per-call APIs and a read-only provider check for x402 buyers. Inspect evidence and live terms before a caller-controlled payment; accept delivery with proof.

## Output

A JSON object containing live Triple Lock signal values specific to the requested symbol, returned after successful x402 payment and proof of accepted delivery. The exact signal fields are route-specific and only revealed post-payment.
