How this service works
Call this before sending money to an unknown agent: Should-I-Pay Lite is the cheapest pre-payment decision — PAY/CAUTION/SKIP + confidence + expected USDC loss for your exact amount. Decision core only; full evidence dossier is in /api/v1/should-i-pay ($0.01). Target by agent_id, solana_asset, seller_url or pay_to. GET or POST with JSON body. No account, no API key
Output
Returns a three-value decision (PAY / CAUTION / SKIP), a confidence score indicating how certain the verdict is, and an estimated expected USDC loss for the specific amount the caller is about to send. This is a lightweight decision-core response; full on-chain evidence is available from the premium endpoint.
Example use cases
Screening an unknown marketplace agent
“I'm about to pay agent ID 1093 around 2 USDC for a service — can you do a quick should-I-pay check and tell me whether it's PAY, CAUTION, or SKIP, and what my expected loss would be?”
Pre-payment check for a Solana AI agent
“Before I send 10 USDC to the Solana agent at pubkey 7xKtZ3...mPqR, do a should-I-pay-lite scan and give me the verdict and confidence level.”
Automated agent payment guardrail
“Every time I'm about to pay a new agent, do a quick cheap reputation check first — for agent ID 332 and a payment of 3 USDC, what's the verdict: PAY, CAUTION, or SKIP?”
Technical details
Endpoint
GEThttps://sweetai.tiamatcrypto.com/api/v1/should-i-pay-lite?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the cheapest possible pre-payment sanity check on an AI agent and don't need the full on-chain evidence dossier. At $0.002 per call it is 5x cheaper than the full /should-i-pay endpoint, making it ideal for automated pipelines that screen many agents or small payment amounts where a thorough audit would cost more than the payment itself. Prefer it for real-time agentic workflows where speed and cost matter more than forensic depth.
Side effects
- Missing both agent_id and solana_asset — returns error requiring at least one identifier
- Invalid or unrecognized agent_id — may return low-confidence SKIP or error
- Malformed solana_asset pubkey — returns parsing error
- Payment of 0.002 USDC not fulfilled — x402 payment required error before response is served
- Amount_usd not provided — verdict returned without expected loss calculation
