Technical details
Endpoint
POSThttps://api.boonprotocol.com/api/v1/x402/reviews/self-reportedWhen to prefer
Use this endpoint when an agent or user wants to submit a cryptographically-signed, subjective text review for a specific x402 API endpoint by its route ID, attested by an Ethereum wallet (EOA or ERC-1271 contract). Prefer this over read endpoints when the goal is to write new review data into the Boon Protocol registry. This is the self-reported review pathway — choose it when the reviewer is attesting their own experience rather than relying on receipt verification or gratuity backing.
