What API cost watchers need from AI usage limit trackers
API cost watchers usually need to answer different questions: what usage has happened, whether a service is having trouble, and when a limit may become available again.
These jobs are related but are not the same. A usage tracker can show spending information from available data. An outage tracker can show service problems. A reset tracker can estimate future limit timing.
The right choice depends on what information matters for the developer's work. Some tools focus on local usage records, some focus on public service status, and some focus on usage limit timing. Check whether a tool answers the specific question that matters before choosing it.
OpenAI Status for API cost watchers
OpenAI Status reports that it is not aware of any issues affecting its systems. [1]
OpenAI Status lists Codex at 99.95% uptime across 4 components. [1] Its uptime metrics are reported at an aggregate level across all tiers, models, and error types. [1]
If the goal is to understand service availability, check what the status page reports for the service you use. If the goal is usage amounts or limit timing, compare the information offered by other options.
ccusage for API cost watchers
ccusage analyzes coding agent CLI token usage and costs from local data. [2]
It reads local usage data from coding agent CLIs and turns it into daily, weekly, monthly, and session reports. [2] It supports sources including Codex, with the command ccusage codex daily. [2]
It can output reports in structured JSON format with the --json flag. [2] It also has an offline mode that uses pre-cached pricing data without network connectivity. [2]
IsDown for API cost watchers
IsDown's Outage Data API provides outage data from 6,320+ vendors. [4]
Its Starter plan for individuals costs $27 per month, or $22 per month when paid annually. [4] It offers a free 14-day trial with no credit card required. [4]
Check whether outage monitoring and the services covered match the needs of the API cost watching task.
StatusGator for API cost watchers
StatusGator monitors the status of 11,270+ services such as cloud infrastructure, hosted applications, and SaaS tools. [5]
It sends Early Warning Signals when possible outages are detected through crowdsourced reports. [5] It lets users publish a unified status page to communicate outages to teams, employees, stakeholders, or customers. [5]
Check whether service monitoring and status communication are the functions needed for the workflow.
Codex Forecast for API cost watchers
Codex Forecast is made by the team that publishes this site. It gives a statistical estimate of when OpenAI will next reset Codex usage limits. [3]
It combines an account it checks every 60 seconds, OpenAI staff announcements and the OpenAI status page. [3] When a measured refill and an announcement disagree, it trusts the measured refill. [3] Each reset used in the forecast is listed with a link to where it was announced. [3]
The forecast is a guess, and a wrong guess means the predicted reset timing does not match the later reset.
You can opt in to free emails that are sent when a reset actually happens. [3] It is free, with no account and no paid tier. [3] It is an independent tracker and is not affiliated with OpenAI. [3] The site and API share a snapshot that is cached up to five minutes. [3]
Matching the tool to the job
To see usage and cost information from local coding agent data, ccusage reads local usage data and turns it into daily, weekly, monthly, and session reports. [2]
To check whether OpenAI has known system issues, OpenAI Status reports on its systems. [1] To monitor many service statuses, StatusGator collects status information for 11,270+ services. [5] IsDown provides outage data from 6,320+ vendors via API. [4]
To estimate when Codex limits reset, Codex Forecast gives a statistical estimate. [3] Its named-day predictions are scored in public, misses included. [3]
To use reset information in another tool, Codex Forecast has a public API that needs no key and gives stats, reset history, forecasts and operational health. [3] The API has a published OpenAPI specification. [3]
Questions to ask before you choose
Which question matters most: tracking your usage, watching service problems, or estimating limit timing?
Do you need local reports from your own computer, a status monitoring service, or a reset estimate?
What services need to be covered? Check whether the tool includes the AI services used by the developer or team.
Do you need information for one person or a group? Team communication features may matter depending on the workflow.
Do you need free access or a paid service? Check the current terms for each option before choosing.
Frequently asked questions
Which tool estimates when Codex usage limits reset?
Codex Forecast gives a statistical estimate of when OpenAI will next reset Codex usage limits, not a promise. [3] The forecast uses listed reset information and can be wrong when the predicted timing does not match the later reset. Each reset used in the forecast is listed with a link to where it was announced. [3]
Can ccusage track Codex usage?
ccusage supports sources including Codex, with the command ccusage codex daily. [2] It reads local usage data from coding agent CLIs and turns it into daily, weekly, monthly, and session reports. [2] Check whether those reports contain the usage information needed for cost watching.
Is Codex Forecast free?
Codex Forecast is free, with no account and no paid tier. [3] Users can opt in to free emails that are sent when a reset actually happens. [3] It is an independent tracker and is not affiliated with OpenAI. [3]
