# Strale Web3 dApp Trust Check

> Strale Web3 dApp Trust Check is a paid API for AI agents from api.strale.io, paid per call via x402, $0.2808/call, status unknown (last checked 2026-10-18).

Checks a Web3 decentralized application (dApp) URL for trust signals and returns an audit record with cryptographic chain hashing.

## 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 strale-web3-dapp-trust-check-a70493cc -d '<json body>'
```

Example prompt: Can you check whether the dApp at https://uniswap.org is trustworthy and safe to connect my wallet to?

## When to prefer this

Use this endpoint when an AI agent or user needs to verify the trustworthiness of a Web3 dApp URL before interacting with it — especially before wallet connections, token approvals, or financial transactions. It is preferable to generic URL safety checkers because it is specifically designed for blockchain/dApp context with cryptographic audit records and Web3-specific trust signals across 27 countries.

## Known failure modes

- Invalid or unreachable URL returns an error or low-confidence result
- URL is not a recognized dApp and produces limited trust signals
- Payment of 0.2808 USDC required per call; insufficient funds causes rejection
- Network timeout if the dApp URL is slow or unresponsive
- Newly deployed dApps may have sparse trust history resulting in inconclusive assessments

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns a structured trust assessment for the given dApp URL, including trust signals, risk indicators, and an audit record with a cryptographic chain hash for tamper-evidence and provenance verification.
