# Protocol & Technology Risk Brief

> Protocol & Technology Risk Brief is a paid API for AI agents from api.x402-engine.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-18).

Generates a decision-ready, cited evidence assessment of a protocol, platform, dependency, or technology covering capabilities, limitations, unresolved risks, and conflicting claims.

## 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 protocol-technology-risk-brief-cfa6a4bb -d '<json body>'
```

Example prompt: Can you pull a technology risk brief on the Ethereum consensus layer, focusing on security and scalability risks over the last 180 days, and compare it against Solana?

## When to prefer this

Choose this endpoint when you need a cited, evidence-backed technology risk assessment with verifiable provenance — especially before adopting a new protocol, dependency, or platform in a production or regulated environment. It is particularly valuable when you need to surface conflicting claims, compare two technologies, or produce a compliance-ready artifact with a hash-bound delivery receipt. Prefer it over generic web search when you need structured, decision-ready output rather than raw search results.

## Known failure modes

- Technology name not recognized or too ambiguous — returns empty or low-confidence results
- Lookback period too short to find relevant public evidence
- Freshness threshold too strict, causing cache miss and slower response
- Conflicting claims cannot be resolved due to insufficient public data
- Version string not matched to any known release — falls back to general assessment
- Risk domains specified are outside supported taxonomy — silently ignored or error returned

## How this service works

Decision-ready public-evidence assessment of a protocol, platform, dependency or technology. Returns cited capabilities, limitations, unresolved risks, conflicting claims and a locally verifiable hash-bound delivery receipt.

## Output

A structured JSON object containing cited capabilities, known limitations, unresolved risks, conflicting claims from public evidence, a focused answer to any specific question posed, and a locally verifiable hash-bound delivery receipt confirming the integrity of the response.
