How this service works
Turn a live x402 paid route, buyer budget, expected payTo/network/asset, runtime, and receipt policy into an agent-payment due diligence pack: dueDiligenceDecision, goNoGoPolicyPack, clientCompatibilityAdapter, receiptEvidencePolicy, repeatPurchasePolicy, firstPaymentRunbook, MCP/Flowise guard configs, and stop conditions. Built for teams that see x402 quotes but need one machine-readable approval artifact before allowing real agent spend. This deterministic endpoint never asks for private keys and never sends a payment header to the target service. GET variant for agents, crawlers, and wallets that prefer query parameters over a JSON body. Pay up to $0.019 per request with x402 USDC on Base.
Output
Returns a structured JSON artifact containing: dueDiligenceDecision (go/no-go), goNoGoPolicyPack, clientCompatibilityAdapter settings, receiptEvidencePolicy, repeatPurchasePolicy, firstPaymentRunbook steps, MCP/Flowise guard configurations, and stop conditions — all machine-readable, no private keys requested, no payment headers sent to target.
Example use cases
Example prompt
“Before my agent starts paying for that route at https://api.example.com/v1/some-service, run a due diligence pack on it — my daily budget is $5 USDC, max $0.05 per call, I expect payTo 0xABC...123 on Base with USDC, my runtime is Node.js, and I want receipt evidence required with human approval on the first payment.”
Technical details
Endpoint
GEThttps://gpt55.558686.xyz/v1/tools/x402-agent-payment-due-diligence-packWhen to prefer
Use this endpoint when an AI agent or orchestration team has received an x402 quote and needs a single, deterministic, machine-readable approval artifact before authorizing real USDC spend — especially when MCP/Flowise guard configs, receipt policies, and stop conditions are needed in one call. Prefer this GET variant when query parameters are more convenient than a JSON body (e.g. crawlers, wallets, simple agent runtimes).
Side effects
- Missing required paid_route/url/endpoint parameter returns validation error
- Invalid or unreachable paid route URL may result in incomplete analysis
- Budget values out of range (below 0.0001 or above limits) return schema validation error
- timeout_ms outside 1000–15000 range rejected
- Payment not made or insufficient USDC balance returns 402 response
