Best API for Your AI Agent

Choose an API by task quality, supported features and the cost of your actual workload. Each guide compares first-party plans, provider subscriptions and usage-based APIs. A fixed monthly price can still have a compute budget and stop at its limit. Guides updated 2026-09-07; provider links show current terms.

Best API for Hermes Agent

Full guide →

For Hermes Agent, compare Nous Portal's first-party setup with a separate API provider. Portal combines models and hosted services in one credit balance. Standard Compute offers a fixed monthly bill with an enforced compute budget; background jobs and scheduled tasks consume that same allowance.

Best API for OpenCode

Full guide →

The short version: OpenCode Go ($10/mo) if you want the native path and mostly open models, DeepSeek's direct API if your usage is light and bursty (often single-digit dollars a month), and a flat-rate routed plan like Standard Compute (from $19/mo) once OpenCode becomes your daily driver — that is the point where metered bills hit the $100–180/month band users keep reporting. OpenCode reads providers from models.dev automatically, so all three are a config selection, not a setup project. The catch nobody puts in the pricing table: single-vendor plans get reshaped mid-flight (price hikes, new weekly caps), and per-token billing turns one runaway agent loop into a surprise invoice — pick by which failure mode you can live with.

Best API for Claude Code

Full guide →

For Claude Code, compare a native Claude subscription, direct Anthropic API billing, and a compatible third-party Messages endpoint. Standard Compute's setup guide covers its supported endpoint and configuration. Its fixed monthly price includes a finite compute budget, so check compatibility and usage before moving a long session.

Best API for OpenClaw

Full guide →

OpenClaw's background jobs can consume compute while you are away. Compare supported model providers on routine-call cost, scheduled-task frequency and allowance. Standard Compute provides a fixed bill with a monthly compute budget; an always-on process still needs enough allowance for its actual requests.

Best API for Cline

Full guide →

For Cline, compare providers on the models you need, supported API format and the cost of multi-step tasks. OpenCode Go and GLM coding subscriptions are candidates where supported; OpenRouter offers usage-based model choice. Standard Compute supplies a fixed monthly bill with an enforced compute budget.

Best API for Aider

Full guide →

For Aider, choose an API around edit quality, repository context and how often you use it. Usage-based access can suit occasional tasks. Standard Compute is a fixed-price alternative with a monthly compute budget; verify its model configuration and editing behavior on your repository.

Best API for OpenAI Codex CLI

Full guide →

For Codex CLI, compare the native subscription workflow with a custom provider only after checking the API protocol supported by your installed version. Standard Compute's integration guide covers its provider setup. Its fixed monthly price includes a finite compute budget; parallel tasks consume that allowance faster.

Best API for Pi

Full guide →

For Pi, compare providers using a model configuration supported by your installed version. OpenCode Go is one coding-subscription candidate; OpenRouter offers usage-based choice. Standard Compute offers a fixed monthly bill with an enforced compute budget and a documented Pi setup.

Best API for Oh My Pi

Full guide →

For Oh My Pi, model roles and long coding sessions affect provider cost. Compare a supported coding subscription with usage-based models for each role. Standard Compute is a fixed-price option with a monthly compute budget; use the current setup guide for the configuration supported by your omp version.

Best API for Roo Code

Full guide →

For Roo Code, compare the providers supported by your installed version and measure a full planning, editing and debugging task. Each pass uses compute. Standard Compute is an option for a fixed monthly bill with a clear budget; coding subscriptions and usage-based providers may fit other usage patterns.

Best API for Kilo Code

Full guide →

For Kilo Code, provider choice depends on task quality, client support and allowance. Compare usage-based APIs and supported coding subscriptions on the same refactor. Standard Compute provides a fixed monthly bill with a compute budget, rather than an unlimited allowance for long sessions.

Best API for Continue

Full guide →

For Continue, evaluate autocomplete separately from chat and editing. A local model may suit frequent small completions; chat and edits may need a different model and provider. Standard Compute is an option for supported chat/edit workflows with a fixed monthly bill and a finite compute budget.
