How this service works
Total cost for multi-endpoint workflow
Output
Returns the total estimated cost in USDC for calling a set of x402 API endpoints as part of a multi-step workflow, allowing agents or users to budget and approve spend before executing paid calls.
Example use cases
Pre-flight cost check for crypto dashboard
“I want to pull crypto prices, gas fees, and fear/greed index from x402 — can you get me a quote for the total cost of that multi-endpoint workflow before I commit?”
Budget planning for data pipeline
“I'm building an agent that calls weather, FX rates, and coin dominance from x402 every hour. Can you estimate what the total USDC cost would be for one full run of all those endpoints?”
Verify charges before payment
“Before my agent pays for the x402 workflow that fetches BTC price history plus current news, can you pull a quote so I can confirm the total cost is what I expect?”
Technical details
Endpoint
GEThttps://x402-api-production-bd43.up.railway.app/quote?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to preview or budget the total USDC cost of a multi-endpoint x402 API workflow before committing to payment. Prefer this over directly calling paid endpoints when cost confirmation is required, or when orchestrating agent workflows that need to verify spend limits.
Side effects

- Invalid HTTP method (non-GET) returns a 400 or schema validation error
- Endpoint unavailable returns 502 or timeout
- No endpoints specified in query results in a zero or error response
