How this service works
Check if a phone number, crypto token, or property address is trustworthy. Returns a 0-100 trust score, confidence, risk flags, and plain-English summary. Detects phone fraud, spam, robocalls, and VoIP; crypto rugpulls, honeypots, and scam tokens; property deed fraud and shady listings. One call, three asset types.
Output
A JSON object containing a numeric trust score from 0 to 100, a confidence value, one or more risk flags (e.g. 'VoIP', 'honeypot', 'deed fraud'), and a plain-English summary explaining the assessment for the queried phone number, crypto token, or property address.
Example use cases
Verify crypto token safety before investing
“Before I invest in this token, can you run a trust score on the contract address 0x2791Bca1f2de4661ED88A30C99a7a9449Aa84174 and let me know if there are any honeypot or rugpull flags I should worry about?”
Screen property addresses for deed fraud
“I'm about to make an offer on a house at 123 Oak Street, Springfield — can you trust-score that property address and flag any deed fraud risks or other red flags before I commit?”
Validate wallet addresses before transfers
“Someone's asking me to send crypto to this wallet address, but I'm not sure if it's legitimate — can you give it a trust score and tell me if there are any scam indicators or risk flags I should know about?”
Technical details
Endpoint
POSThttps://trustscore.dev/api/scoreWhen to prefer
Use this endpoint when you need a fast, single-call fraud or trust assessment for exactly one asset — a phone number, crypto token, or property address — and want a unified score with human-readable explanation. Prefer this over the bulk endpoint when checking just one item, and prefer it over raw blockchain or carrier lookup APIs when you want a pre-interpreted trust score with risk flags rather than raw data.
Side effects
- Invalid or unrecognized asset type — endpoint cannot determine which scoring model to apply
- Malformed phone number format — returns error or low-confidence result
- Unverified or very new crypto token with no on-chain history — may return low confidence score
- Property address not found in deed records — returns low confidence or error
- Rate limiting or payment failure if x402 payment is not properly attached
- Network timeout if underlying data sources are slow to respond
