How this service works
Looks up a wallet's live token/NFT approvals via the GoPlus Security API and explains them in plain language for people with no crypto background.
Output
Returns a JSON object with a 'verdict' field set to one of SAFE, CAUTION, or RISK, and an 'explanation' field containing a plain-language description of what the approval does and why it carries that risk level — written for users with no crypto background.
Example use cases
Pre-signing approval safety check
“Before I sign this approval, can you look at this token permission data and tell me in plain English if it's SAFE, a CAUTION, or a RISK — and explain what I'd actually be agreeing to?”
Auditing existing wallet approvals
“I want to review my current wallet approvals — can you analyze this approval data from my wallet and explain what each permission means and whether any of them are risky?”
NFT collection approval review
“I just got prompted to approve this NFT collection contract — here's the approval data. Can you tell me if it's safe, give me a risk rating, and explain it like I'm not a crypto expert?”
Technical details
Endpoint
POSThttps://smartcontractexplainer.onrender.com/api/explain?utm_source=zero.xyzWhen to prefer
Use this endpoint when a user needs to understand wallet token or NFT approvals in human-readable terms before signing, especially when they lack crypto knowledge. Prefer this over raw blockchain explorers or security APIs when the output needs to be non-technical and verdict-driven (SAFE/CAUTION/RISK). Ideal for consumer-facing agents that help users avoid phishing or malicious approvals.
Side effects
- Missing or malformed 'data' field in request body returns an error
- GoPlus Security API unavailable or rate-limited causing lookup failure
- Unrecognized approval payload format resulting in inability to parse permissions
- Network timeout from GoPlus upstream causing delayed or empty response
- Payment of $0.05 USDC not completed causing 402 rejection before processing
