The short version

  • Each has a real cost: Apigee the free evaluation is a sandbox limited to 60 days; Sila no pricing is published, so you cannot compare Sila against Moov or Dwolla without entering two sales processes, and small programmes frequently find the monthly minimum dominates their cost at low volume.
  • They diverge on capability: Apigee covers API Gateway, Sila covers ACH origination.
  • 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.

Apigee

  • The free evaluation is a sandbox limited to 60 days
  • Pay-as-you-go has no SLA available at all
  • Pay-as-you-go bills environments separately from API calls, with a Base environment costing $365 per month per region
  • The Base environment is capped at 50 QPS with an SLA of up to 99%
  • Standard API Proxy calls are billed at $20 per 1M calls up to 50M, and Extensible API Proxy calls at $100 per 1M calls up to 50M
  • API Analytics is a paid add-on at $20 per 1M API calls and cannot be bought on a Base environment
  • Advanced API Security is a paid add-on at $350 per 1M API calls and cannot be bought on a Base environment
  • Monetization is unavailable on pay-as-you-go and requires a subscription tier
  • Additional API proxy deployments beyond those included cost $0.04 per hour per region on a Comprehensive environment
  • Subscription tiers Standard, Enterprise and Enterprise Plus are quote only with no published price
  • Google Cloud networking charges for IP addresses, data transfer out and forwarding rules are billed on top of Apigee usage

Sila

  • No pricing is published, so you cannot compare Sila against Moov or Dwolla without entering two sales processes, and small programmes frequently find the monthly minimum dominates their cost at low volume.
  • Sila is materially smaller and less well capitalised than the banking-as-a-service names it competes with, which matters because your customer funds and your payment rails depend on the vendor still trading in three years.
  • The sponsor bank behind your programme determines what you can offer and how fast you can change it, and bank partnerships in this sector have been reshuffled repeatedly since 2023, so a bank change during your contract is a realistic risk rather than a theoretical one.
  • Coverage is United States only, so any product with cross-border ambitions needs a second payments vendor and a second reconciliation process from the outset.
  • Onboarding involves compliance diligence on your own programme, and teams routinely underestimate this, with weeks lost between signing and first live transaction while policies, flow of funds diagrams and BSA arrangements are reviewed.
