name: paysafe-agent.com
description: paysafe-agent.com provides a single pre-payment screening endpoint that analyzes an x402 payment request for fraud and safety issues before an agent signs and submits the transaction. It checks for nonce reuse, recipient address mismatches, overpayment, prompt-injection triggers, PII leakage, and counterparty reputation, returning a verdict and risk score. It does not execute payments, track on-chain state, or provide price data.

# paysafe-agent.com

paysafe-agent.com is a fraud-screening intermediary for autonomous agents operating in the x402 payment protocol. It serves agents that receive 402 payment offers from untrusted or semi-trusted sources and need a structured safety check before committing funds. Its distinguishing function is pre-execution risk assessment across multiple fraud vectors in a single call, rather than any payment execution or financial data capability.

## When to use this host

Use paysafe-agent.com when an agent receives a 402 payment offer and cannot independently verify the recipient address, nonce freshness, or resource URL, and needs a structured risk verdict before signing. It is the right choice for any agent operating in adversarial or low-trust environments where payment requests may be spoofed or injected. Do not use it to check on-chain transaction status after submission — it has no post-execution visibility. Do not use it as a price oracle or balance checker; it has no market data capability. For those needs, route to a dedicated price-feed or blockchain-data host. If the agent needs to actually execute the payment after screening, a separate x402-compatible payment execution host is required.

## Capabilities

### Pre-Payment Fraud Screening

Screens an inbound x402 payment request across multiple risk dimensions — nonce reuse, address pinning, overpayment, prompt injection, PII leakage, and counterparty reputation — and returns a verdict with a risk score before the agent pays.

- **`scan-incoming-payment`** — Screens an x402 payment request for fraud indicators including nonce reuse, recipient address pinning mismatches, overpayment, prompt-injection triggers, PII leakage, and counterparty reputation before the agent pays.

## Skill reference

### `scan-incoming-payment`

**Incoming Payment Scanner** — Screens an x402 payment request for fraud indicators including nonce reuse, recipient address pinning mismatches, overpayment, prompt-injection triggers, PII leakage, and counterparty reputation before the agent pays.

*Use when:* Use when an agent receives a 402 payment offer and needs to verify it is safe to pay before signing and submitting the transaction — especially when the recipient address, nonce, or resource URL cannot be independently verified.

*Not for:* Do not use for scanning outgoing payments already submitted on-chain; this endpoint screens payment requests before execution, not after. Not a real-time price feed or balance checker.

**Inputs:**

- `payment` (object, required) — The payment or 402 offer to screen. Include as many fields as available: scheme, network, asset, amount, amount_usd, asset_decimals, pay_to, payer, resource_url, description, reason, nonce, valid_until, metadata.
- `agent_id` (string) — Stable identifier for the calling agent; scopes velocity limits across repeated scans.
- `expected_price_usd` (number) — What the agent expected this payment to cost in USD (e.g. from the 402 quote or a catalog). Enables overpayment detection.
- `context` (object) — Provenance of the decision to pay (e.g. {"origin": "planning"}). Used to detect prompt-injection-triggered payments.

**Returns:** Returns a scan_id, overall verdict (allow/block), risk_score 0–100, an array of named checks each with their own verdict and severity, a plain-language advisory, and an ed25519-signed attestation with a 5-minute expiry.

**Example:** `{"agent_id":"agent-42","expected_price_usd":0.05,"context":{"origin":"planning"},"payment":{"nonce":"0x1a2b3c","amount":"50000","pay_to":"0x209693Bc6afc0C5328bA36FaF03C514EF312287C","scheme":"exact","network":"eip155:8453","description":"Premium data access","resource_url":"https://api.example.com/premium","asset_decimals":6}}`
