Spraay Trust & Safety

Verify before you pay. Free address safety screening (phishing, sanctions, exploits, mixers), free token honeypot checks, free transaction decoding, plus paid multi-dimensional agent trust scores via ProofLayer — all through the Spraay x402 gateway. Vet any counterparty before funds move.

What it does

Verify before you pay. Free address safety screening (phishing, sanctions, exploits, mixers), free token safety checks (honeypot, sell tax, blacklist), free transaction decoding, and paid multi-dimensional agent trust scores via ProofLayer — all through the Spraay x402 gateway. Use when the user asks to verify an agent or wallet, check a trust score or reputation, vet a counterparty before a payment or escrow, screen an address for safety, check if a token is a honeypot, or decode a transaction.

The skill document

Spraay Trust & Safety 💧

Verify before you pay. Free safety screening plus ProofLayer trust scoring for agent-to-agent commerce, via the Spraay x402 gateway.

All requests in this skill go exclusively to the user's configured SPRAAY_GATEWAY_URL. No data is sent to any other external endpoint.

Important Notes

A trust score is a signal, not a guarantee. Scores are derived from on-chain signals, reliability history, and reputation data. A high score reduces risk; it does not eliminate it. For meaningful amounts, combine a trust check with escrow (see the spraay-escrow skill) rather than relying on either alone.

New agents score low by default. An unscored or low-scored agent is not necessarily malicious — it may simply be new. Treat "no history" and "bad history" differently when advising the user.

Setup

The gateway URL must be set in your environment or openclaw.json:

SPRAAY_GATEWAY_URL=https://gateway.spraay.app

No API key is needed. The paid trust score endpoint uses the x402 HTTP payment protocol (HTTP 402 → pay → retry). An x402-compatible wallet (Coinbase CDP or similar) handles this automatically. The three safety endpoints are completely free.

Workflows

Address Safety Screen — FREE

Screen any recipient before sending funds: phishing, sanctions, exploit involvement, mixer usage, malicious contracts.

curl "$SPRAAY_GATEWAY_URL/api/v1/address/safety?address=0xABC...123"

Run this before every first-time payment. It costs nothing.

Token Safety Check — FREE

Pre-trade token check: honeypot detection, sell tax, mint/blacklist functions, proxy risk. GoPlus-powered with Spraay severity scoring.

curl "$SPRAAY_GATEWAY_URL/api/v1/token/safety?address=0xTOKEN...&chain=base"

Decode a Transaction — FREE

Plain-English summary plus structured token transfers for any EVM transaction — swaps, transfers, approvals, wraps, NFTs, batch payments. Use it to verify what a transaction actually did.

curl "$SPRAAY_GATEWAY_URL/api/v1/tx/decode?hash=0xTXHASH...&chain=base"

Agent Trust Score — $0.03

Multi-dimensional wallet/agent trust score via ProofLayer: financial, reliability, trust, and social axes, plus XMTP reputation and on-chain signals. Counterparty due diligence for agent-to-agent payments.

curl "$SPRAAY_GATEWAY_URL/api/v1/trust/score?address=0xABC...123"

If you receive HTTP 402, the response body contains payment instructions. Pay the facilitator, then retry with the X-PAYMENT header containing the proof.

Interpreting Results

Safety screen fails (sanctions, phishing, exploits) — recommend against transacting, full stop.
Safety clean + strong trust score — established counterparty. Direct payment is reasonable for routine amounts.
Safety clean + weak or moderate score — some history. Use escrow for anything non-trivial.
Safety clean + no score / no history — new agent. Not a red flag by itself; use escrow and small amounts first.

Recommended Pre-Payment Flow

Run the free address safety screen. Hard stop on sanctions/phishing hits.
For agent counterparties or larger amounts, fetch the trust score ($0.03).
Based on results: pay directly (spraay-payments), escrow first (spraay-escrow), or decline.
After payment, decode the transaction (free) to confirm what happened on-chain.

Free Endpoints

These require no x402 payment:

GET /api/v1/address/safety — Address safety screen
GET /api/v1/token/safety — Token honeypot/risk check
GET /api/v1/tx/decode — Transaction decoder
GET /health — Gateway health check

x402 Payment Flow

Call the trust score endpoint.
Receive HTTP 402 with payment details (accepts array with amount, asset, and payment address).
Agent wallet sends the micropayment ($0.03 in USDC on Base).
Retry the request with the X-PAYMENT proof header.
Receive the response.

Error Handling

402 — Payment required. Follow instructions in response body.
400 — Bad request. Check the address/hash format.
404 — No record for this address (new agent — see interpretation notes).
500 — Server error. Retry after a moment.

Tips

The safety screen is free — run it before every first payment, always.
Reserve the paid trust score for agent counterparties and larger amounts.
Pair a weak/no-score result with spraay-escrow instead of refusing outright.
Decode transactions after the fact to verify delivery of on-chain work.
