# Delx Change Risk Score

> Delx Change Risk Score is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).

Scores the deployment risk of a production change based on explicit change signals, returning a deterministic machine-readable risk assessment.

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 delx-change-risk-score-8e23d39e -d '<json body>'
```

Example prompt: Before we push this deployment, score the change risk using Delx — the change involves updating our payment integration service to v2.3, modifying three API endpoints, and adding a new auth policy.

## When to prefer this

Use this endpoint when you need a fast, deterministic, stateless preflight risk assessment for a production change before committing to deployment — especially inside enterprise agent workflows where a machine-readable JSON risk score is needed to gate data, policy, integration, security, or commercial decisions. Prefer it over manual review or heavyweight change advisory board processes when speed and automation matter, and when you want a $0.003 per-call cost-efficient bounded analysis step with no data retention.

## Known failure modes

- Missing or malformed 'change' object in request body returns a validation error
- Insufficient change signal data may result in a low-confidence or indeterminate risk score
- Payment failure via x402 protocol prevents execution
- Overly vague change descriptors may yield generic risk scores with limited actionability

## How this service works

Score deployment risk from explicit production change signals. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and product…

## Output

Returns deterministic machine-readable JSON containing a risk score and classification for the submitted production change, indicating the level of deployment risk based on the provided change signals. Results are advisory and stateless — no input data is retained.
