## 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 forwardlane-dd-health-check-4d137c55
```

Example prompt: Can you quickly check whether the ForwardLane Due Diligence API is up and healthy before we kick off the full pipeline run?

## When to prefer this

Use this endpoint as a zero-cost pre-flight check before invoking any paid ForwardLane DD endpoints such as deep repo analysis or pipeline runs. Prefer this when building retry logic, monitoring integrations, or validating API reachability in automated agent workflows. Not useful for retrieving actual financial code intelligence data.

## Known failure modes

- Service unavailable (HTTP 503) if the ForwardLane backend is down or under maintenance
- Network timeout if the proxy layer is unreachable
- Unexpected non-200 response if upstream ForwardLane API is degraded
- Empty or malformed JSON if the health handler itself has an error

## How this service works

ForwardLane's Agentic APIs expose the FL Repos Intelligence platform: a code knowledge graph, financial-ontology code mappings, technical due-diligence metrics, code quality scores, security findings, and SWE-bench style evaluation tasks, all computed over 151 private financial-services repositories. Every endpoint is a synchronous read that returns JSON. This server is a pay-per-use, transparent proxy in front of ForwardLane's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. The complete verified paid surface is listed at /openapi.json, the source of truth for available operations. Each operation here carries its live price in x-payment-info. Use the operations and details here when they meet your needs. Filtered specs contain only matching operations; if you cannot find what you need here, use search or the service catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge, reserved for agents claimed by a human with a verified email.

## Output

A JSON response indicating whether the ForwardLane Due Diligence API service is operational, typically including a status field (e.g. 'ok' or 'healthy') and possibly service version or uptime metadata. Returns HTTP 200 on success with no cost incurred.
