How to choose
Match the API to your primary bottleneck: data ingestion, model routing, or action execution. Teams running multi-model setups should prioritize gateways like Oxlo.ai or Auriko to control spend. Watch for regional compliance needs and private inference requirements before choosing general-purpose options. Avoid over-indexing on raw model performance when integration simplicity and output consistency matter more for agent reliability.
