Terms of Service
These terms govern your use of the Stitch API, the model API proxy run by Provenance Research ("Stitch", "we"). By creating an account you agree to them on behalf of the company you name at signup, and you confirm you're authorised to do so.
The service
Stitch forwards your requests to model providers (such as Anthropic, OpenAI, Google, xAI, Mistral and DeepSeek) and returns their responses. You choose an endpoint for each API key:
- Zero data retention (ZDR): we don't store the content of your requests or responses. We keep usage metadata (time, model, token counts, cost, status) to bill you and run the service.
- Recording: we store a copy of each request and response after automatically removing secrets, email addresses and similar personal details, and we may use those copies to build and improve datasets and models, including ones we license to others. Automatic redaction is not perfect: don't send data through a recording key that you aren't permitted to share with us.
What a model provider retains is governed by the provider account the call runs on: yours if you send your own provider key, ours otherwise.
Your account and keys
- Keep API keys secret. Anyone with a key can make calls billed to your account, up to that key's daily limit. Revoke a key you think is exposed.
- Members you add can manage keys and buy credit for the account. The owner is responsible for the account.
- You must comply with the usage policies of each model provider you call through Stitch, and with applicable law.
Credit and payment
- Calls on Stitch's provider keys are paid from prepaid credit you buy by card through Stripe. Each call is charged at the provider's standard token price for that model, as listed on our prices page at the time of the call.
- Taxes may be added at checkout. Payments are processed by our payment providers, which may act as merchant of record.
- Credit doesn't expire while your account is open. Except where the law requires otherwise, credit is non-refundable and non-transferable and has no cash value. Credit that was bought with a payment later refunded or reversed is removed, and the balance may go below zero.
- We may put an account on hold, pausing calls on Stitch credit and points redemptions, while a payment dispute or suspected misuse is investigated.
Travel points
Calls on Stitch credit earn travel points, which we use to book flights and hotels for you, as set out in the Travel Points terms.
Acceptable use
Don't use Stitch to break the law, to infringe others' rights, to attack or disrupt the service or any provider, to evade a provider's safety systems or rate limits, or to resell access to Stitch without our written agreement. We may suspend or close accounts that do.
Availability and changes
We aim to keep Stitch available but don't guarantee uninterrupted service, and the models available depend on our providers. We may change these terms or the service; we'll tell account owners by email of material changes before they take effect. Continuing to use Stitch after that means you accept them.
Disclaimers and liability
Stitch and model outputs are provided "as is", without warranties of any kind, to the extent the law allows. Model outputs can be wrong; you're responsible for how you use them. To the extent the law allows, our total liability for any claim relating to Stitch is limited to the amount you paid us in the 12 months before the claim, and we aren't liable for indirect or consequential losses.
Ending
You can stop using Stitch at any time; contact us to close your account. We may close accounts that breach these terms. Sections on payment, liability and recorded data survive closure.
