No LLM API gives you infinite usage; the closest thing is a flat-rate LLM API: one fixed monthly price for a stated compute budget, with no per-token bill and no overage. Standard Compute is one, built for coding agents that run all day: it selects providers for price and performance and routes tasks across efficient and frontier models to make your compute go further. Plans start at $19/month, and the pricing and usage details below explain what you get.
Eligible new accounts can activate $0.25 of trial compute with no card. Connect your agent, try it on your own code, and choose the capacity that fits your work.

Works in every agent with a custom OpenAI-compatible provider: OpenClaw and Hermes Agent (paste-in guides), OpenCode, Cline, Kilo Code, Pi, Codex CLI, Cursor and more. Step-by-step guides: /integrations.
For vibe coding (long, exploratory agent sessions in tools like OpenCode, Cline or Claude Code), the two things that ruin the flow are usage limits and surprise bills. Capped plans (Claude Pro/Max, Codex, OpenCode Go) interrupt sessions with 5-hour or weekly windows; per-token APIs let the meter run while you're in flow. A flat-rate plan like Standard Compute is built for exactly this: fixed monthly price, no session windows, smart routing across frontier and open models, so a long vibe-coding night costs the same as a quiet one.
Three habits: use open-source agents (OpenCode, Cline, Aider: your workflow survives any provider switch), use OpenAI-compatible endpoints (switching providers is a base-URL swap, not a rewrite), and avoid annual contracts. Standard Compute is deliberately anti-lock-in on all three: open agents are the target users, the endpoint is OpenAI-compatible (plus Anthropic Messages format), plans are monthly with a 7-day fair refund. If you leave, you change one URL back.
A flat monthly price does not mean unlimited usage. Standard Compute charges a fixed monthly price and includes a stated monthly compute budget. Plans include a fixed monthly compute budget, from $19/mo, with no per-token meter and none of the 5-hour or weekly windows most flat plans impose. Smart routing draws on the full model landscape, so you reach frontier quality and get the most intelligence per dollar. Requests are not slowed based on how much of your budget you have used. They run normally until your monthly budget is reached, then stop until renewal or an upgrade.
Two honest trade-offs, both by design. First, smart routing picks the model per request rather than pinning one version, so you're never stuck on a deprecated model. Second, 'unlimited' here means no per-token meter, not infinite usage: plans carry a fixed monthly compute budget, and requests run normally until it is reached. There is no slowdown based on how much you have used, and no surprise charges, so you always know exactly how much you have spent and how much you have left. If you need hard real-time latency guarantees, per-token providers fit better.
Standard Compute is the fixed-price option for coding agents: a monthly plan from $19 with an OpenAI- and Anthropic-compatible key, where a looping agent can spend at most the plan's compute budget and then gets HTTP 402 until renewal or an upgrade, with nothing billed as overage. The other shapes are a prepaid per-token account that stops at a zero balance, which still bills every token up to that point, and reserved capacity such as Amazon Bedrock Provisioned Throughput, billed by the hour whether you use it or not. If you keep your own API key, our free runawayguard proxy (/tools/runaway-guard) puts a dollar limit in front of it.
Watch the live budget in your dashboard and cap the agent itself: set a step or retry limit, use a backoff on errors, and stop loops that repeat the same failing call. Requests run at full speed until the monthly budget is used, then stop until renewal or an upgrade, so a runaway loop can never create a surprise bill. If an always-on agent regularly needs more, upgrade, or on Economy and above turn on Pay as you go top-ups. (Smart pacing, which slowed requests to spread the budget, was retired in October 2026.)
Roughly when your monthly per-token bill exceeds the flat plan price. Always-on agents cross that line fast: they resend large context every step, so input tokens dominate and a 24/7 agent commonly burns $100–500/month per-token. Light or bursty usage (a few million tokens a month) is genuinely cheaper per-token.
Flat-rate APIs that are OpenAI-compatible drop into any agent that accepts a custom base URL: set base URL to https://api.stdcmpt.com/v1, paste your API key, set model to standardcompute. OpenClaw, Hermes Agent, OpenCode, Cline, Aider, Codex CLI, Cursor and most other agents support this. Setup guides for each are on the integrations page.
A fixed monthly price is not a guarantee against API errors or limits. Standard Compute has a monthly compute budget: requests stop when it is used, until renewal or an upgrade. A high anti-abuse request-rate ceiling also applies; past it the API returns 429 with a Retry-After header. Your agent should still handle transient failures and respect the API's retry guidance.
Standard Compute routes across current frontier models (GPT-class, Claude-class, Gemini-class) and efficient open models, picking per request based on the task and load. You get frontier-quality output without managing a model menu, and the router, not a fixed version string, decides which model serves each request.
