Frequently asked questions about Token swap quote

How much does a token swap quote API call cost?

Endpoints listed for defi.swap_quote on EntRoute are priced from $0.001 to $0.5 per call. Payment is per request — there is no subscription, account or API key. Prices shown are read from each endpoint's live 402 response, not from a provider-supplied catalogue.

How do AI agents pay for token swap quote endpoints?

Via the x402 protocol. The agent calls the endpoint, receives an HTTP 402 Payment Required response describing the price and recipient, signs a stablecoin payment (USDC on Base), and retries the request with proof of payment. The whole exchange takes seconds and needs no human approval.

How many providers offer token swap quote?

50+ endpoints are currently listed for defi.swap_quote across 5 providers. That number moves as endpoints are added and as failing ones are demoted.

Are these token swap quote endpoints verified?

Each one is probed every 10 minutes to confirm it still returns a well-formed 402 challenge on a payable network. Endpoints whose 7-day success rate drops below 50% are moved out of the ranked list into fallbacks with an explicit exclusion reason, so an agent can decide whether to retry them.
