# TWZRD Agent Intel – Solana Merchant Trust Score

> TWZRD Agent Intel – Solana Merchant Trust Score is a paid API for AI agents from intel.twzrd.xyz, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-11).

Returns a paid trust/reputation score and signed V7 receipt for a Solana merchant pubkey, derived from settlement-graph analysis, to help AI agents make pre-spend trust decisions over the x402 protocol.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 twzrd-agent-intel-solana-merchant-trust-score-3fe01ca2
```

Example prompt: Before I pay this Solana merchant GWRLgRB6diC2zG9BaoGJsan9T8JvJCk7usFruiefnfMP via x402, check their trust score and get me a signed receipt so I know if the payment is safe.

## When to prefer this

Use this endpoint when an AI agent needs a cryptographically signed, on-chain-anchored trust score for a specific Solana merchant before committing an x402 micropayment. Prefer it over free preflight (/v1/intel/preflight) when you need a V7 signed receipt for audit trails or when paid renormalized scoring is required. Not a substitute for on-chain verification or a wallet service.

## Known failure modes

- Payment not settled on-chain — endpoint returns unpaid/unauthorized response
- Invalid or malformed Solana pubkey in path parameter — returns 400 or empty result
- Score advisory only — a high score does not guarantee off-chain delivery
- Merchant not found in settlement graph — may return null score or low-confidence result
- x402 payment rail misconfiguration — incorrect feePayer pin causes failed gas-sponsored settlement

## How this service works

Pre-spend trust layer for AI agents paying over x402 on Solana. Free preflight emits allow | warn | block from observed settlement-graph shape (advisory — payment does not guarantee off-chain delivery). Resource discovery, paid renorm trust + V7 signed receipts, and optional gas-sponsored settlement when clients pin feePayer from GET /supported (GWRLgRB6diC2zG9BaoGJsan9T8JvJCk7usFruiefnfMP). Not a wallet or payment network. Path A: paid trust intel 402 — bind the accepts[] entry you pay. Settle rail: opt-in /supported feePayer. Path B = buyer AutoGate refuse (signer=0). Buyer gate package: twzrd-x402-gate@0.9.7.

## Output

Returns a JSON object containing: a boolean 'paid' field confirming payment, a numeric trust 'score' (e.g. 61.8), a signed 'receipt' object with a keccak256 leaf, version 7, the settlement transaction as preimage, and an Ed25519 signature, plus the 'score_version' label (e.g. intel_renorm_v1_1).
