Metering

Chirio meters network writes. One unit is one write to one platform:

• publishing a post to one connected account — 1 write
• posting that post's first comment — another write
• reposting a published target — another write (billed at most once per target, and never with the link surcharge — a repost carries no text)
• reposting any other post URL — one write per account that reshares it, billed at most once per account and post

A post to Instagram, Threads and LinkedIn with a first comment on each is therefore 6 writes. Nothing else is metered. Listing accounts, reading post history, reading metrics and failed requests are free. Scheduling a post costs nothing until it goes out: the write is billed at dispatch, so a post you cancel before its time was never billed. Not every write costs the same to serve, because not every platform charges the same to write to. The multiplier is applied at the moment of the write and frozen, so a later price change never rewrites what you were already billed. Link detection is deliberately generous: a scheme-less example.com/blocks still counts, because X treats it as a link too. Every billable write carries an idempotency key, so a retry — or a poll that keeps finding the same condition true — is billed once no matter how many times you call: The second row is the one that matters in practice. "Repost once it passes 500 likes" is a poll, and a threshold stays crossed — meanwhile X answers a repeated retweet exactly as it answers the first, so nothing in the platform's response tells a duplicate from an original. Chirio's ledger does, which is what makes it safe to run that check on a schedule. Usage is recorded after an outcome, never before:
