## How to call it through Zero

## When to prefer this

Use this endpoint when you need fail-to-deliver ratio data for a specific stock ticker and are operating in an x402 pay-per-call environment. Prefer this over broader financial data APIs when you specifically need FTD metrics rather than price, volume, or fundamental data.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Payment not accepted results in no data delivery (HTTP 402)
- Symbol path parameter missing causes a malformed request error
- Service may return stale or unavailable data for thinly-traded or delisted securities

## 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 the FTD ratio and associated metrics for the requested ticker symbol, returned after successful payment acceptance. The example response indicates 'SML FTD Ratio' as the product with route-specific live values delivered post-payment.
