## 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 aeml-x402-trust-scorecard-bulk-export-2b726707
```

Example prompt: Pull the full trust scorecard for all x402 services — I want to see the score_total, liveness_state, lifecycle, and record_hash for all 1,601 services in the latest snapshot.

## When to prefer this

Choose this endpoint when you need a comprehensive, all-at-once bulk export of trust scores across the entire x402 service ecosystem rather than querying individual services. It is the right choice for ecosystem audits, building trust-ranked directories of x402 services, or detecting lifecycle and liveness changes at scale. Note that sub-score detail and verification fields are currently unavailable, so prefer this only when aggregate score_total and liveness_state are sufficient for your use case.

## Known failure modes

- Payment not received or invalid x402 USDC payment on Base — returns 402 Payment Required
- Upstream data unavailable — five-axis sub-scores, action_hint, and verified fields return empty or are listed in unavailable_fields
- Stale data — snapshot is from 2026-07-08 and may not reflect current service states
- Service downtime on Zeabur hosting — potential 503 or timeout responses

## How this service works

[BATCH+PROOF] Full x402 service demand roster, latest day: demand_class, calls_30d, unique_payers_30d, score_total, liveness_state, lifecycle, record_hash per service. Model demand-v1, refreshed daily from the public CDP catalogue; unique_payers_30d is a lower bound, never a sum. DEGRADED DELIVERY, see unavailable_fields - the five-axis sub-scores, action_hint, tier and verified are empty. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.

## Output

Returns a JSON object with a 'rows' array containing up to 1,601 service records, each including score_total, liveness_state, lifecycle, and record_hash fields, plus a 'count' integer. Note: five-axis sub-scores, action_hint, and verified fields are unavailable (listed in unavailable_fields) due to upstream collector stoppage. Snapshot is dated 2026-07-08 and is explicitly marked stale.
