Know exactly what AI costs — before the invoice tells you.
Meterlark tracks published API pricing for every major model, continuously, so "what will this cost" has a real answer instead of a guess. The directory and calculators are free forever. When you want to see what you're actually spending, the workspace is $19/month.

Example workload, not a recommendation — the priciest model here costs 129x the cheapest for the same volume. Run your own numbers on the calculator.
The problem
Your AI spend lives in six different consoles, and none of them talk to each other.
OpenAI's usage page shows OpenAI. Anthropic's shows Anthropic. Whatever you're paying Google, Mistral or whoever else lives wherever they decided to put it. Nobody hands you the one number that actually matters: what AI cost this month, total, across every model your team touches.
Prices also move without much warning — a provider cuts input pricing, adds a cache tier, or ships a new flagship that quietly makes last quarter's cost model wrong. Catching that requires someone to keep checking every provider's pricing page by hand, which nobody actually has time to do.
The directory
79 models, one page, prices that are actually current.
Every model gets checked against its provider's own pricing page, not scraped once and left to rot. Anything we couldn't independently verify is labelled as such instead of quietly presented as fact.

Calculators
"What will this cost" answered in one page load.
Put in a token volume and request rate, get an exact cost from live pricing — no spreadsheet, no digging through a provider's tier structure to find the number you actually need.
Open the calculatorThe workspace
The directory tells you what AI costs. The workspace tells you what it's costing you.
Create a project per product, team or client. Log usage by hand, or drop in a CSV export from a provider's dashboard — either way, cost is computed from the same verified pricing you see in the directory, not whatever the provider chose to invoice you.

Built for agents too
A pricing directory an agent can actually read.
Every model in the directory — all 79 of them — is available as plain JSON through the public API, plus an llms.txt summary for agents that just need the shape of the dataset before they call it. No auth for read access, no scraping.
