# Open Horizon ABF Stress Snapshot

> Open Horizon ABF Stress Snapshot is a paid API for AI agents from ohd-machine-x402-v2.hibiki3027.workers.dev, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-02).

Queries a DeFi lending stress-test dataset to return health-factor snapshots, liquidatable episode counts, and risk summaries for asset-backed finance positions across protocols and chains.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 open-horizon-abf-stress-snapshot-5b230075 -d '<json body>'
```

Example prompt: Pull a stress snapshot for the top 10 most at-risk USDC loan positions on Ethereum using Morpho, sorted by minimum health factor ascending, and flag any that are already liquidatable.

## When to prefer this

Use this endpoint when you need machine-verifiable DeFi lending stress data with health-factor granularity, especially for liquidation risk triage, protocol risk comparison, or automated credit-risk pipelines that require an attestable result flag. Prefer it over general blockchain data APIs when you specifically need episode-level ABF stress snapshots with rich filtering by chain, protocol, asset pair, and borrow/collateral size bucket.

## Known failure modes

- Payment not provided or insufficient USDC via x402 — request blocked before fulfillment
- Invalid enum value for sort_by or order fields — schema validation error
- Chain or protocol name not recognized in dataset — returns zero matched episodes
- limit exceeds maximum of 25 — schema rejection
- No episodes match the filter combination — summary returns zero counts

## How this service works

Agent decision products for procurement, vendor risk, API QA and public-web buy-or-skip workflows. Strict x402 payment is required before fulfillment.

## Output

Returns a JSON object containing a summary with minimum health factor, matched episode count, and liquidatable episode count, plus a machine_verifiable boolean confirming the result is cryptographically attestable. Optionally echoes back the query parameters used.
