Paycheck

PayCheck ($0.50): before you pay this agent, check.

Overview

PayCheck ($0.50): before you pay this agent, check. ONE call runs Flow's whole checker stack on a payee — the payee verdict (kind, activity, the full contract-safety engine when the payee is a contract), the wallet approval-exposure audit, contract safety, and the payee's recent USDC settlement history on Base — and returns one finished grade (ALLOW / REVIEW / BLOCK, 0-100 score), a verify_status (verified / failed / unverified_verifier_down), every check, the evidence under it, and a receipt. The guarantee: the report is produced before settlement; if it cannot be produced, the payment is never settled — no report, no charge. Body: { payee, chain?, amountUsd? } — Base only in v1. A bad $50 payment is gone forever; the check is $0.50. + Flow Promise coverage.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/paycheck \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/paycheck \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
