# klymax402 Trust Score API

> klymax402 Trust Score API is a paid API for AI agents from klymax402.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Evaluates the trustworthiness of a domain, URL, wallet address, or IP by running SSL, DNS, WHOIS, HTTP headers, and content checks to produce a composite trust score and grade.

## 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 klymax402-trust-score-api-55680681
```

Example prompt: Can you check the trust score for example.com — run all checks including SSL, DNS, WHOIS, headers, and content — and tell me the grade and verdict?

## When to prefer this

Use this endpoint when you need a multi-signal trust assessment combining SSL certificate validity, DNS health, WHOIS registration data, HTTP response headers, and content signals in a single call. It is especially useful for evaluating unfamiliar domains, URLs, or crypto wallet addresses before interacting with them. Prefer it over single-signal checks (e.g. SSL-only tools) when you want a holistic grade and verdict rather than raw certificate data.

## Known failure modes

- Invalid or unresolvable target returns an error or low score
- Network timeouts on full scans (3-8s) may cause delays
- Wallet address format errors if not a valid 0x address
- Partial check failures if a specific check type (e.g. WHOIS) is unavailable for the target
- Rate limiting or payment failure for the $0.02 USDC per call fee

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a JSON object containing the target evaluated, a composite trust score (numeric), a letter grade, a verdict (e.g. trusted/suspicious/untrusted), a breakdown of subscores per check type (ssl, dns, whois, headers, content), the entity type, and a timestamp of the evaluation.
