Billing

How cloro charges for API usage: subscription tiers, monthly credit grants, concurrency ceilings, renewal timing, and the difference between self-serve and enterprise agreements.

Overview

cloro runs on a subscription model. Each plan grants a fixed pool of credits every month and sets a ceiling on how many requests you can run in parallel. You spend credits as your calls succeed, and the pool resets when your billing cycle turns over.

Every tier, from the smallest self-serve plan upward, ships with the same baseline capabilities:

• Full access to the public API surface
• Per-response headers that report remaining credits and current concurrency usage
• A dashboard for tracking consumption and managing your subscription

Current tiers, concurrency limits, and per-plan pricing are listed on the cloro website.

How credits are spent

Credits are the unit of account for the API. The rules that govern them are straightforward:

• A fresh allocation lands in your account when each billing cycle begins.
• Credits are drawn down only when a request finishes successfully.
• Requests that fail with a 4xx or 5xx status are not charged.
• The cost of a successful call depends on the endpoint and the options you enable.
• Synchronous monitor calls carry a fixed surcharge of 7 credits per successful request.

Expiration

Credits are scoped to a single billing period. Anything left unspent when the cycle closes is forfeited; balances never carry into the following month. Pace your workloads across the cycle so you extract the full value of your allocation.

Billing cycles

All plans bill monthly. Your cycle is anchored to the day you first subscribed and renews on that same calendar day each month. Renewal is automatic and continues until you cancel.

Managing your subscription

Subscription changes are made from the dashboard:

• Upgrade — Move to a larger tier at any time with immediate effect. The remaining days of your current cycle are prorated, and credits you have already consumed are subtracted from the new plan's grant.
• Monitor — Review your live balance, usage trends, and past invoices.
• Cancel — Access remains active through the end of the paid period; unused credits are not refunded.

Payment details, billing address, tax identifiers, and invoice history are all editable through the dashboard's billing section. Updates you make there apply to invoices going forward.

Public vs. enterprise plans

Public plans

Public plans activate instantly and are entirely self-directed:

• Subscribe, upgrade, or cancel yourself from the dashboard.
• No overage billing — the API simply stops serving once credits reach zero.
• Begin issuing requests the moment your subscription is live.

When a public plan's balance is exhausted, calls are rejected until you either upgrade to a larger tier (effective at once) or wait for the next cycle's allocation to arrive.

Enterprise plans

Enterprise agreements suit high-volume workloads with requirements a public tier can't cover. Minimum commitments are published on the cloro pricing page. Typical enterprise terms include:

• Locked pricing — Rates are held steady for the contract term even as upstream costs shift.
• Volume rates — A lower effective cost per credit at scale.
• Overage tolerance — Service keeps running past your planned allocation rather than halting.
• Expanded concurrency — Parallel-request limits sized to your throughput.
• Custom deals — Per-model pricing tailored to your use case.
• Multiple organizations — Separate queues under one shared billing plan.
• Term contract — A 12-month agreement backed by SLAs.
• Reserved endpoints — Access to routes available only to enterprise accounts.
• Invoiced payment — Net-7 monthly settlement by bank transfer or direct debit.

To start, request a quote from [email protected]. Once terms are agreed, cloro issues a contract for signature and provisions your plan in parallel; you supply a billing contact and, where relevant, how concurrency should be divided across organizations. New rates apply as soon as the switch is made, and additional concurrency is typically online within two to three days of payment clearing.

Common questions

Do unused credits roll over?

No. Any credits left at the end of a cycle expire and do not transfer to the next period.

How do I check my balance?

Open the dashboard to see your current balance, spend for the active cycle, a projection based on recent usage, and your historical consumption.

What happens when I run out of credits?

Once your balance hits zero, further calls are refused with a 403 Insufficient Credits response. Upgrading to a higher tier restores service immediately. cloro emails you when you cross the 80% and 100% usage marks so a stoppage never catches you off guard.

Are cancellations refundable?

Unused credits are not refunded on cancellation. Your account stays active — with full access to any remaining credits — until the current cycle ends, and no further charges are made after that.
