# Boon Route Reviews — Paginated Onchain Review History for x402 Endpoints

> Boon Route Reviews — Paginated Onchain Review History for x402 Endpoints is a paid API for AI agents from api.boonprotocol.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Retrieves paginated, cryptographically-signed review history for a specific x402 route, including reviewer signatures, USDC-backed recognition signals, and tipper verification status.

## 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 boon-route-reviews-paginated-onchain-review-history-for-x402-endpoints-caf773c1
```

Example prompt: Pull up the full review history for x402 route 0x1212121212121212121212121212121212121212121212121212121212121212 — show me the first 25 reviews and let me know which ones have verified tipper signatures and on-chain recognition.

## When to prefer this

Use this endpoint when you need the full signed review history for a specific x402 route and want cryptographic verification of reviewer identity and tipper status. Prefer this over free discovery endpoints when the depth and authenticity of review data matters — e.g., before committing an agent to repeatedly call a paid x402 service. The $0.01 USDC cost is justified when review credibility (signature validity, on-chain recognition) is a decision factor.

## Known failure modes

- Invalid routeId format (must match ^0x[0-9a-fA-F]{64}$) returns a 400 or validation error
- Route not found returns empty reviews array or 404
- Payment not provided or invalid x402 payment header returns 402 Payment Required
- Offset beyond total review count returns empty results with hasMore=false
- Limit outside range 1-100 returns a validation error

## How this service works

Boon is the gratuity graph for agents. Discover recognized x402 endpoints for free, compare signed reviews with USDC recognition and $BOON burned, then pay one cent through x402 or MPP only for full review history.

## Output

Returns a JSON object containing a paginated array of reviews for the specified x402 route. Each review includes the review text, a reviewer signature validity flag, a boolean indicating whether the reviewer was an actual tipper, and a routed recognition verification status. Also includes route ID, schema version, and pagination metadata (limit, offset, total count, hasMore flag).
