## 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 truthbear-stablecoin-deaths-8de748f7
```

Example prompt: Pull the full stablecoin deaths dataset from TruthBear — I want the forensic snapshots of every terminated stablecoin including price, supply, collateral, termination type, confirmed death date, and days alive, and include the hash core so I can verify each record offline.

## When to prefer this

Choose this endpoint when you need a neutral, forensic, batch record of all historically terminated stablecoins for base-rate analysis, post-mortem research, academic citation, or risk modeling. It is uniquely suited for offline-verifiable audit workflows due to its record_hash infrastructure. Prefer this over live monitoring endpoints when your use case is retrospective or statistical rather than predictive.

## Known failure modes

- 422 no_charge — no matching stablecoin death data available, not billed
- Network timeout on large batch payload
- Invalid query parameter value for verifiable field
- Payment failure via x402 protocol before data is returned

## How this service works

[BATCH+PROOF] Stablecoin death samples - a neutral record: the full pre-mortem snapshot of terminated stablecoins (price, supply, collateral, redemption) plus lifecycle context (termination type, confirmed death date, days alive). Forensic depth for base-rate and post-mortem work, not a rating and not an endorsement. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. Every record carries an offline-recomputable record_hash. $0.09 per call.

## Output

A batch JSON response containing one record per terminated stablecoin, each with pre-mortem snapshots (price, supply, collateral, redemption), lifecycle context (termination type, confirmed death date, days alive), and an offline-recomputable record_hash. Optionally includes _hash_core per row for full offline verification. Returns 422 with no charge if no data is available.
