## 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 pulsefeed-trust-dataset-bulk-x402-service-trust-data-4973b170 -d '<json body>'
```

Example prompt: Pull the full PulseFeed x402 trust dataset right now — I want every audited service's trust score, pay/avoid verdict, scam flags, and payTo change history in one shot; include dead endpoints too.

## When to prefer this

Choose this endpoint when you need trust data for many x402 services at once and want to avoid scraping or calling individual trust endpoints one by one. Ideal for builders of monitoring dashboards, trust tools, or uptime trackers that need a comprehensive snapshot of the entire x402 ecosystem. Use the per-endpoint sibling endpoints instead if you only need to vet a single service before paying.

## Known failure modes

- Payment not received or insufficient USDC — endpoint returns 402 with payment instructions
- Invalid query parameters (e.g. non-integer limit) — likely 400 bad request
- Dataset temporarily unavailable — possible 503 if upstream indexing is delayed
- Empty dataset if no x402 endpoints have been indexed yet
- Rate limiting if called too frequently without payment

## How this service works

Bulk trust data for every x402 service in one call. For builders of trust, uptime and monitoring tools: each service's full profile — 0-100 trust score and pay/avoid verdict, scam flags, receiver stability, on-chain receiver profile, plus the compounding payTo and price change history. Skip scraping hundreds of endpoints. ?all=1 includes dead ones, ?limit=N. Free preview: /status.json, /data/sample.

## Output

A JSON dataset containing every audited x402 endpoint's full trust profile: 0–100 trust score, pay/avoid verdict, scam flags, receiver stability rating, on-chain receiver profile, compounding payTo change history, and price change history. Optionally includes dead/offline endpoints (?all=1) and can be paginated (?limit=N).
