Plans
Both plans run the same platform at the same published rates; the only difference is the credit each paid month includes.
- The 7-day free trial is on Standard only. A card is required to start it, the trial grants $10 of credit (none on a prepaid card, a card whose security-code check fails or cannot run, or a card that already started a trial), and unless you cancel before it ends it converts to $20 per month with the full $20 of credit. One trial per organization and one per person.
- Included credit rolls over. It is added to your organization’s prepaid balance alongside anything you top up, and it never expires.
- Upgrade to Pro any time from the Credits page, under Settings → Credits (or
vetta plan change --plan pro). It takes effect at once: the difference for the rest of the month is charged now, and upgrading during the trial ends the trial and charges $200. - Moving back to Standard takes effect at the end of the month already paid for. Nothing is refunded and the Pro credit already granted stays in the balance.
What you pay for
Every rate published here and on Limits & billing is the price you pay — the number the ledger books and the number your spend breakdown reports. There is no separate fee, no seat charge and no minimum on top of it.
Priced tools
Several tool families have a price of their own, on top of the tokens the model spends calling them. Each appears onGET /v1/agents/{id}/spend?by=component under its own component name. An app’s database is not one of them: /v1/apps/{id}/db/* calls and the apps tool’s db_* actions carry no price of their own.
They are all booked after the fact. A web call is priced from what the provider charged for it, so the debit lands after the call: an agent already at its cap can still make one. Media is the same — nothing is reserved before a render (see below), so max_task_micro_usd does not bound one; a character training is the one media job held first. Watch the search and media components to see what each is costing, and treat the agent’s cap_micro_usd and the organization’s balance as the real limits.
Web tools — per call, search component
The listed price is the price you pay:
data_search, data_describe and GET /v1/social_data/tools report it. The median per-call data tool is about $0.002, seven in ten cost $0.013 or less, and the most expensive is about $1.24; most social data tools are $0.0039 per call. Some tools are priced per result, at most 25 results per run.
Data and social data runs are the exception to booking after the fact: a run is admitted first, capped at 25 results and admitted at its most it can cost — through the API, the balance must cover the tool’s listed price for one call (or for 30 results on a per-result tool, since some sources bill results in blocks of 10), else 402 insufficient_credits; from an agent, the run takes a hold against the session’s budget. A data or social data run that fails — refused input, a network error — is not charged. A run past its two-minute limit is stopped and normally not charged; one the source meters per result costs what it gathered before the stop. Searching for and describing a data or social data tool is free.
A search whose results are all filtered out by the agent’s domain policy still costs the call — the query ran. A web_fetch refused by that policy is stopped before the page is requested and costs nothing; a page that redirected somewhere the policy forbids is withheld after the fetch, and that one is billed, because the fetch happened.
Media generation — per finished job, media component
You are billed what the finished job actually cost, once per job.
There is no per-model price table here, and that is deliberate rather than an omission. A generation job’s cost depends on the model, the duration and the size, and the catalogue changes without a release of ours — so a table on this page would be stale the day a model is added. A video on a model priced per generated second costs its length at the resolution it renders at (720p on the platform’s per-second models, unless it says otherwise); every other job costs what its model reported for it. What can be listed is which models exist: GET /v1/media/models, read live from the provider. The audio routes and tools are on this component too: a transcription costs what the provider charged for the recording, speech what it charged for the characters spoken, and a sound effect what it charged for the seconds generated, and a song the same, for the seconds of music generated.
Nothing is reserved for an image or a video before it renders. Most renders cannot be priced before they run, and a ceiling is not a price, so no hold is taken against the agent’s budget and no balance floor is checked, from a session or over REST. The real cost is booked once, when the job lands, on the render’s own idempotency key; a render costs cents, and a balance may go negative by one rather than turn the request away. A job that fails or never finishes is not billed at all.
A character training is held first and billed once. create_character takes a hold against the session’s budget before anything is bought — a budget with no room refuses it — and asks by default. Over REST, the prepaid balance must cover one training first (402 insufficient_credits otherwise). The training, from a session or over REST, is billed once, on the media component, when the trainer accepts the photos; a request refused before then is not billed, and a training that later ends failed is refunded, on the read that sees it fail. A replay under the same key charges nothing.
An edit with Mira (edit_video) has a set price, and is held. An edit with no photos costs $0.03 per second of the source clip, rounded up to whole seconds, at 720p; clips are trimmed to 15 s, so it costs at most $0.45. An edit with photos, or a person swap, is $1.48 at any length, at 1080p. The price is held against the agent’s budget at submit: the clip’s own length when it is known, else 15 s. Every finished edit is billed, including one you asked for again. An edit that fails, is refused, times out, or is cancelled while queued costs nothing.
A clipping job submitted over REST has no agent, so no reservation. POST /v1/media/clips is admitted while the prepaid balance is above zero (402 insufficient_credits otherwise), and what it can cost is bounded server-side instead: the input is capped at 90 minutes of video and every metered actual the job reports is clamped before it is priced. The debit lands once, on completion; a failed job bills nothing.
3D assets
A generated 3D model (generate_3d_model, POST /v1/media/meshes) is one charge for the finished model. The amount depends only on which model ran and on texture and rig. Render time, file size and polygon count leave it unchanged. It is booked on the media component when the job completes; a failed job is free. GET /v1/media/models?kind=mesh lists that charge for every option, as prices[].micro_usd.
A built model (
build_3d, POST /v1/computers/{id}/build-3d) has no price of its own: it runs on the agent’s computer and is billed as that computer’s running seconds, on the computer component. On an agent’s computer ($0.0666 an hour) a CAD part with three 768 px previews takes about a minute and a half, about `$0.002`; the first call also installs the toolchain, about 20 seconds more.
Browser — per session minute and per hosted action, browser component
The minutes are one debit when the session closes; there is no up-front hold, because a session’s cost is knowable only at close. A session is capped at 360 minutes (
timeout_minutes); one that hits its timeout bills up to it and no further. The deterministic actions (goto, click, type, screenshot, links, …) cost nothing beyond the minutes they run in. The whole model is on Limits & billing.
Voice calls — per started minute, voice component
The minutes are one debit when the call ends. Starting a call needs a balance of at least one minute (otherwise
402 insufficient_credits), a call is capped at 10 minutes ($1.04), and a call whose balance runs out mid-way is told so and hung up. What the agent says is billed as model inference, exactly as in a typed chat.
Mobile sandbox — per device-minute, mobile component
The minutes are one debit when the device ends — on delete, on its idle timer, at its maximum duration, or when the platform stops it because the balance or plan no longer covers it (
termination_reason: "unfunded"). There is no up-front hold. Looks, taps and every other action cost nothing beyond the minutes they run in, and a device that fails to provision bills nothing. Creating one needs a balance above zero. The whole model is on Limits & billing.
Storage — per bucket-day, storage component
Storage on a fullstack app is metered per bucket per UTC day it exists, on its own storage line — and no rate is published for it today, so no line is booked. The tier exists on the ledger so a rate can be set without a schema change; until one is, buckets and objects carry no charge beyond the computer time an agent spends using them.
The model proxy
POST /v1/proxy/anthropic/v1/messages is priced exactly like a session’s model call — same catalogue, same per-window tariff, same five tiers, same balance. The proxy adds no charge of its own.
The completion window is the biggest lever
The same model at a different window is a different price. The window is a single field with three wire values —immediate, priority, and loose.
You choose the window per request — pay the interactive tariff only when a person is waiting; overnight work runs on
loose for materially less.
On immediate, the router picks the fastest provider hosting the model rather than the cheapest, because that window exists for the case where a person is waiting. The same model can therefore cost a little more on one call than another — you are billed from what the call actually cost, and the ledger records which provider served it.
Budgets keep it predictable
Every agent has a budget: setcap_micro_usd, max_task_micro_usd, and a period. Model calls are quoted before they run, so one that would breach those ceilings is refused rather than discovered on an invoice. Media renders, compute and the web tools are metered from what they actually used and booked afterwards, so a period’s spend can finish past its cap — and, where a funded organization exhausts its balance mid-turn, the balance itself can go negative. It is on the ledger either way, never silent.
