Example use cases
Cheapest facilitator for new agent service
“I'm launching an AI agent service that will make about 20,000 x402 API calls per month at $0.005 each — can you compare the main x402 facilitators and tell me which one will cost me the least?”
Cost comparison against current provider
“We're currently using one x402 facilitator and want to see if switching makes sense — compare providers for 100,000 monthly calls at $0.01 average price, and use our current setup as the reference baseline.”
Budget planning for high-volume agent pipeline
“Help me plan our monthly x402 payment costs — we expect around 500,000 agent API calls per month at an average of $0.002 per call, and I need a cost breakdown across available facilitators to present to finance.”

Endpoint
POSThttps://api.blockchainmoneymap.com/api/x402/x402-facilitator-cost-comparatorWhen to prefer
Use this endpoint when you need to programmatically compare the total cost of different x402 payment facilitators before committing to one for a production agent or API service. It is especially useful for high-volume scenarios where small per-call fee differences compound significantly, or when evaluating a switch from an existing provider using the reference_facts baseline feature.
