Can I use Temporal for stateless APIs?
Not recommended – Temporal is designed for long-running, stateful workflows. For simple request-response, it adds unnecessary complexity.
Does Echo support all LLM providers?
Echo's unified gateway supports 100+ models from OpenAI, Anthropic, and Google Gemini. For non-mainstream providers, check their GitHub for updates.
What is a Billable Action in Temporal?
A Billable Action is an API call (e.g., starting a workflow, completing an activity) used for metering. Recent news introduced the Billable Action Count metric for cost transparency.
How does Echo make money if developers pay nothing?
Echo charges a 2.5% fee on the revenue developers earn from token markups. Developers set their own markup – Echo takes a cut only when developers profit.
Is Temporal open-source?
Yes, Temporal Server is open-source (MIT License). Temporal Cloud is a managed service with usage-based billing.
Can I self-host Temporal?
Yes, Temporal Server can be self-hosted. The free tier includes the full functionality for on-premises deployments.
Does Echo require Stripe integration?
No, Echo handles all billing internally – developers don't need to integrate Stripe. Users top up via Echo's system.
Which tool is better for AI agents?
For reliability and durability, Temporal is stronger with automatic retries and state capture. For cost efficiency and simple integration, Echo is better if you want users to pay for inference.
