FAQ
Short answers to the questions developers ask first.
Do I need a subscription?
No. Register free, buy tokens from US$15 and spend them on fits; nothing renews. The membership ($200 a month) is a separate offer that adds a managed agent workspace, data tools and weekly plan credits.
How much does a fit cost?
Typically 20–30 tokens (US$20–30) for the first fit on new data: grounding your economics (17–20) plus compute (3–10). Repeat fits with the same description and schema reuse the compiled economics. Cost follows the size of your history and menus; the pricing page has the rates.
How is this different from a decision or classification API?
Those pick one answer from a list you define, in milliseconds, one item at a time. P34 decides a whole menu at once: it calibrates to your history and your costs, then returns a size for every option and the predicted profit of the plan. That takes minutes, and it is built for buying decisions where most options should be refused.
Can I try it before paying?
Yes. POST /validate needs no key and no account, and input tests with "mock": true are free on every key. Only actual fits spend tokens.
What happens when my balance runs out?
Calls that need tokens are refused with HTTP 429, and nothing is queued or charged for a refused call. Validation and input tests keep working. Buy tokens in the console and resubmit.
Do tokens expire?
No. Tokens you buy stay on your balance and never expire. They are not refundable.
How fast is it?
A fit takes minutes: it grounds your history, calibrates the model and decides the whole menu. It is built for purchasing-style decisions, not sub-second ones.
What data do I need?
Menus of candidate deals — hundreds at least on the current one — with past menus that include the options nobody took, a sales log of what happened, and a paragraph on your unit economics. No trading record? A history assembled from market research is accepted. See Prepare your data.
Is there an SDK?
It is plain HTTPS and JSON, so any HTTP client works. We publish a standard-library Python quickstart, a sample client and a pytest workflow in P34-API-DOCS, plus four agent skills.
What if my key leaks?
Revoke it in the console (API keys → revoke) and create a new one; a revoked key stops working at once. Keep keys in environment variables, one per application or agent, never in code, logs or URLs.
What happens to my data?
It is used to compute your fits. You can cancel a running fit and discard the session with DELETE /session/{id}. Data handling is governed by the API Terms of Use and our privacy policy.
Is there an SLA?
Not during the beta: the service is provided as available, and limits can change. GET /health reports whether the service is up.
Which model version should I use?
default, unless you need results that never move — then pin a version and upgrade deliberately. Models.
What is the difference between pay as you go and Membership?
Pay as you go is the API alone, paid in tokens. Membership ($200 a month) adds a managed agent workspace, data tools and a monthly token grant. Compare them.
Which markets can I use it on?
Any market whose decisions look like a menu of deals and whose outcomes you can measure. Trading regulated securities, derivatives or prediction markets is outside the self-serve terms. See the computable-markets catalogue.
