Newton’sTerms of Service
Last updated .
Service
Newton’s is an OpenAI-compatible API service. Features, model availability, upstream processors, published prices, and traffic policies may change as the service evolves. No production service-level agreement is included unless separately signed.
Account activation
New accounts are created without funded credits. You must purchase prepaid Credits before making paid model requests. In these Terms, “Credits” means the non-transferable prepaid service credit described below. Newton’s may require Turnstile, mobile verification, or other abuse controls and may pause new activation when model, payment, or capacity evidence is unavailable.
Account verification and security messages
During a limited key-only launch, account creation may use Cloudflare Turnstile and network-level abuse controls instead of a mobile number. The API key is shown once and can later be exchanged for a secure dashboard session. A key-only account cannot be recovered if every active key and every browser session are lost. When mobile verification is offered, passwordless sign-in requires a supported mobile number; VoIP, landline, toll-free, invalid, and unclassified numbers are not eligible. By requesting a code, you consent to receive one transactional SMS security code for that request from Newton’s. Message and data rates may apply. Message delivery may be delayed or unavailable because of carrier or network conditions, and carriers are not responsible for delayed or undelivered messages. Reply STOP to opt out where supported; reply HELP or emailfounders@newtons.dev for help. Opting out prevents SMS-based access until another supported authentication method is offered. Consent to security texts is not consent to marketing texts.
Purchased Credits
Newton’s offers one-time Credit purchases in the U.S.-dollar amounts displayed by the dashboard and checkout at the time of purchase. Each top-up is a one-time purchase and does not renew automatically. Purchased service credit is non-transferable, has no cash value, and is consumed at the published model rates in effect when a request is accepted. Purchased Credits do not expire while the account remains open, except where applicable law permits otherwise after prolonged account inactivity or closure.
Pricing and Credits
Model prices are published in U.S. dollars and may distinguish input, output, cached-input, reasoning, tool, or fixed-request charges. The dashboard and API may show estimated costs before final usage is known. The final charge is based on measured usage and the applicable published rate. Agent requests stop when the available Credits cannot cover the required reservation. Newton’s does not create an open-ended usage bill or extend credit.
Model identity
A request for a specific published model ID remains pinned to that ID unless you explicitly request a documented fallback. Newton’s does not silently replace it to reduce cost. If the reported model ID is unconfirmed or mismatched, the request returns an error. Models may be suspended when capacity, identity, pricing, authorization, or safety requirements cannot be verified.
Upstream processing and credentials
Published models may use one or more upstream inference processors and model providers. Newton’s may use configured inference processors for particular models. Your Newton’s API key authenticates your request to Newton’s and is not forwarded as a provider credential. Some models may use an account-scoped provider credential; others may use Newton’s shared upstream service credentials. Per-account provider-credential isolation is therefore model- and configuration-dependent, not a guarantee for every request. These processing arrangements do not change the pinned-model behavior or the response record provided for an accepted call. Provider commercial account details are not exposed in public API traffic.
Refunds, disputes, and reversals
Top-ups are generally non-refundable after service credit is used, except where required by law or when we confirm duplicate or erroneous billing. Approved refunds remove the associated unused Credits. A payment reversal, chargeback, or dispute may cause the related Credits to be reversed and the account to be restricted. If reversed credit has already been consumed, we may suspend further requests until the outstanding Credit obligation is resolved. Contact us before initiating a dispute so we can investigate billing errors promptly.
Acceptable use
Do not use the service for unlawful activity, credential abuse, attempts to evade provider restrictions, denial of service, unauthorized scraping, or extraction of protected model behavior. Rate, concurrency, request-size, safety, fraud, and model-availability controls still apply. We may suspend traffic or accounts when reasonably necessary to protect builders, payment systems, upstream capacity, or the service.
