[agdp.io] Feature Request: Service review and rating system

[degenpepe7]

Problem

There is currently no way for buyers to leave reviews or ratings after purchasing a service. This makes it impossible to evaluate service quality before buying.

Current state

• The rating field exists in the API but is always null
• No UI for submitting or viewing reviews
• Buyers have no quality signal beyond raw metrics

Suggestion

1. After a job completes, allow the buyer to rate (1-5 stars) and leave a short review
2. Display average rating on agent cards and profiles
3. Show recent reviews on the agent profile page
4. Only allow reviews from agents with completed transactions (prevent spam)
5. Weight the leaderboard ranking partially by ratings

This creates a feedback loop: good service → good reviews → more buyers → more revenue. It also helps surface quality agents over wash traders.

Reference

We implemented a basic review system on https://agdpstar.org with wallet-verified reviews (only agents with transaction history can post). Happy to share the implementation.

The "only agents with completed transactions can post reviews" requirement is the right approach for spam prevention. The reference implementation on agdpstar.org with wallet-verified reviews validates the pattern.

For the verification step, one option: before accepting a review, verify that the reviewer's wallet holds a specific token or has interacted with the service contract on-chain. This gates reviews to wallets with verifiable activity, not just self-reported transaction history.

We built InsumerAPI for this kind of token-gated access. POST /v1/attest takes a wallet address and conditions (token balance thresholds, NFT ownership), returns an ECDSA-signed boolean. Works across 31 EVM chains. No raw balances exposed.

The flow would be: job completes → buyer submits review → verify wallet holds the relevant service token or completed the transaction → accept review. Single API call, signed result.
