The short version

  • Only AWS API Gateway has a free tier, so it costs nothing to try first.
  • Each has a real cost: AWS API Gateway rEST APIs cost $3.50 per million calls against $1.00 for HTTP APIs, so the older and more featureful type is three and a half times dearer; Dwolla nothing is published: there are no per-transaction rates, no platform fee and no minimum on the pricing page, so every buyer negotiates blind and small platforms have no way to sanity check what they are quoted.
  • They diverge on capability: AWS API Gateway covers REST APIs, Dwolla covers ACH transfers.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

AWS API Gateway

  • REST APIs cost $3.50 per million calls against $1.00 for HTTP APIs, so the older and more featureful type is three and a half times dearer
  • Data transfer out is charged at $0.09 per GB on top of request pricing
  • WebSocket APIs bill connection minutes as well as messages, at $0.25 per million minutes
  • Private APIs avoid data transfer charges but incur AWS PrivateLink costs instead
  • The developer portal is $125 a month, with additional portal products at $12.50 each
  • The free tier lasts 12 months rather than being ongoing

Dwolla

  • Nothing is published: there are no per-transaction rates, no platform fee and no minimum on the pricing page, so every buyer negotiates blind and small platforms have no way to sanity check what they are quoted.
  • It is payments only, with no deposit accounts, card issuing or general ledger, so companies embedding financial products need at least one further vendor and the reconciliation between them.
  • Instant payment reach depends on the receiving institution supporting RTP or FedNow, so a meaningful share of payouts still fall back to ACH timing regardless of what the API can do.
  • ACH returns and administrative returns remain your operational problem, and platforms new to bank rails routinely underestimate the customer support load that failed debits generate.
  • Access to instant rails runs through Dwolla banking partner, which reintroduces a bank dependency into a product that otherwise avoids sponsor bank programme risk.
