Terms of Service

1. Who we are and what Callstand is

Callstand ("Callstand", "we", "us") is operated from Mexico by the owner of callstand.com. By creating an account or using the service you agree to these terms. If you use Callstand on behalf of a company, you confirm you are authorized to bind that company.

Callstand is a platform. We provide the tools: accounts, the builder and calibration tools, access control, metering, billing, and the technical interface (MCP and API) through which a Callstand can be called. Every account can build its own Callstand and can use Callstands that other account holders share with it.

People who share their Callstand with you are independent of us. They are not our employees, agents, partners, or contractors, and we do not supervise, direct, or guarantee their judgment. Callstand does not handle payments between account holders and is not a party to any arrangement between you and anyone whose Callstand you use, or who uses yours.

2. Accounts

You must be at least 18 years old and provide an accurate email address. You are responsible for everything that happens under your account, including all activity by your software and any person you allow to use it.

API keys are credentials. Anyone holding your key can spend your credits and use every Callstand your account can use. Keep keys secret, never commit them to public code, and replace a key immediately if it may have been exposed. You can replace your key at any time from your dashboard. We are not responsible for calls made with your key before you replace it.

We may require email verification and may refuse, suspend, or close accounts as described in section 11.

3. Credits and payment

• Callstand runs on prepaid credits. 1 credit represents $0.01 USD of call value.
• Credit purchases are processed by Stripe. We never receive or store your full card details. The price shown at checkout includes card processing costs.
• Credits are a prepaid balance for using the service. They are not money, not a stored-value instrument, not a deposit, and earn no interest. They are non-transferable between accounts and have no cash value outside the platform.
• New accounts may receive free starter credits. Free credits have no cash value and are not refundable.
• Credits do not expire while your account is open and in good standing.
• Prices are stated in USD. You are responsible for any taxes applicable to you, and for any currency conversion or fees charged by your bank or card issuer.

Refunds. Purchased credits are generally non-refundable once bought, because they can be spent immediately. If credits were purchased in error, are entirely unused, and you contact us within 14 days, we will usually refund them at our discretion. If we refund a purchase, we deduct the corresponding credits from your balance; if you have already spent them, we may refund only the unspent portion.

4. Calls, pricing, and refunds on individual calls

• Each call costs a flat price set by Callstand and shown in your dashboard, currently $0.50 (50 credits) per call, on any Callstand and for any verb. The person making the call pays it from their own credits.
• We may change the price per call. Changes apply to future calls only, and the current price is always shown in your dashboard.
• Calls may include an optional max_price. If the current price exceeds it, the call is rejected before any work is performed and nothing is charged.
• Credits are reserved when the call starts. If the call fails with a technical error, or the model declines to answer, the credits are returned to your balance automatically.
• A call that completes and returns an answer is a delivered service and is charged, even if you are unhappy with the answer. If you believe an answer was materially defective, contact us and we will look at it in good faith; remedies are at our discretion and are typically a credit adjustment.
• The building tools (generating calibration test cases and running side-by-side tests) include a free allowance per account. Beyond it, each run costs the credits shown in your dashboard before you run it.
• We apply rate limits and input size limits to keep the service stable. Exceeding them results in a rejected call, not a charge.

5. Your Callstand and your material

Your material

You keep full ownership of everything you bring to Callstand: your descriptions, calibrations, examples, guidance, and any other material you use to build your Callstand ("your material"). You grant us a non-exclusive, worldwide, royalty-free licence to store, process, and use that material solely to operate your Callstand and provide the service, including sending the necessary parts of it to our model provider to produce answers to calls. We do not use your material to build or improve Callstands for anyone else, and we do not sell it.

You are responsible for having the rights to everything you upload, and for not including material you are contractually or legally barred from using, such as another client's confidential information, unless you are permitted to do so.

Publishing

You decide when your Callstand is published, and you can pause it at any time. We may suspend or remove a Callstand at any time, including for legal risk, safety, or breach of these terms. A Callstand being available on our platform is not an endorsement, certification, or verification of anyone's credentials.

Your responsibility for answers

You are responsible for the judgment your Callstand expresses to the people you share it with, in the same way you are responsible for advice you give directly. You must not configure a Callstand to provide services you are not permitted to provide, or in a regulated field where doing so through software would breach applicable rules.

6. Sharing, and using shared Callstands

• You choose who may use your Callstand. Access requires your approval by default; you may instead let anyone with your link use it, and you may remove anyone's access at any time, effective immediately.
• Everyone pays for their own calls from their own credits, including when they use a Callstand someone shared with them. Callstand does not collect, hold, or pay out money on behalf of account holders. If you charge others for access to your Callstand, that arrangement is solely between you and them, and you are responsible for any obligations it creates.
• Having an account does not entitle you to use any particular Callstand. Access is granted by each Callstand's owner.
• You are responsible for what you send. Do not send information you are not allowed to share, and do not send sensitive personal data, health, financial account, or government identification data through calls.
• Answers are provided for your own use in your work. You may use and adapt them freely (see section 9), but you must not resell or redistribute answers from someone else's Callstand as a standalone product or service, or use them to build a Callstand that imitates theirs.
• You are responsible for reviewing answers before acting on them (see section 8).

7. Acceptable use

You agree not to:

• attempt to extract, reconstruct, or reverse engineer a Callstand's underlying material, configuration, or system instructions, including by prompt injection or any similar technique;
• use the service to train, fine-tune, distil, or otherwise build a competing model or service;
• circumvent access controls, rate limits, pricing, or billing, or share your key to give access to people who were denied it;
• use the service for anything unlawful, harmful, deceptive, harassing, infringing, or that violates another person's rights or privacy;
• upload malware, probe or attack the platform, or interfere with its operation or with other users;
• misrepresent an answer as human-delivered advice given in real time, or as coming from a person whose Callstand did not produce it.

We may investigate suspected violations and take any action we consider appropriate, including suspension, removal, and reporting to authorities.

8. Nature of the answers, and no professional advice

Answers are generated by software configured to reflect a person's judgment, as encoded in their Callstand. They are produced automatically, without that person reviewing the specific request or answer. They can be incomplete, out of date, or wrong, and they may not fit your particular circumstances.

Nothing on Callstand is legal, medical, tax, accounting, financial, or other regulated professional advice, and no professional-client relationship is created by making a call. Use professional judgment and human review before acting on an answer, especially where money, safety, legal exposure, or people are involved. Any decision you take, and its consequences, are yours.

The service does not browse the web or access live data unless you provide that information in your request, and it may reason from facts that have changed since a Callstand was configured.

9. Intellectual property

• Your material stays owned by you, as described in section 5.
• Inputs you send stay owned by you.
• Answers: as between the parties, the owner of a Callstand grants the person calling it the rights needed to use, adapt, and commercially exploit the answer in their own work, subject to the restrictions in section 6. Answers may not be unique; similar requests may produce similar answers for other people.
• The platform, including the Callstand name, site, software, and design, belongs to us. Nothing here grants you a licence to it beyond using the service as intended.

10. Confidentiality of your material

People who use a Callstand receive answers, not access. We do not disclose a Callstand's underlying material, examples, calibrations, or configuration to anyone it is shared with, and our system is designed to refuse requests aimed at extracting it. No safeguard is perfect, and we do not warrant that determined attempts to extract material will always fail.

11. Availability, suspension, and termination

We aim to keep Callstand available but we do not promise uninterrupted service. We may change, suspend, or discontinue features, and we may perform maintenance, at any time.

You may stop using the service or ask us to close your account at any time. We may suspend or terminate an account for breach of these terms, legal risk, suspected fraud or abuse, or non-payment.

If we terminate your account without cause, we will refund unspent purchased credits. If we terminate for breach or fraud, we may withhold unspent credits to the extent needed to cover losses, chargebacks, or amounts owed. Sections that by their nature should survive termination do survive it, including sections 7 through 12.

12. Disclaimers and limitation of liability

To the maximum extent permitted by law, the service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including any warranty of merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that answers will be accurate, complete, suitable, or that they will produce any particular result.

To the maximum extent permitted by law, we are not liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, revenue, data, business, or goodwill, however caused.

Our total aggregate liability to you for all claims relating to the service is limited to the greater of (a) the total amounts you paid to Callstand in the three months before the event giving rise to the claim, or (b) $100 USD.

Nothing in these terms excludes or limits liability that cannot lawfully be excluded or limited, including for fraud, or for death or personal injury caused by negligence. Some jurisdictions do not allow certain exclusions, so parts of this section may not apply to you.

Indemnity. You agree to indemnify and hold us harmless from claims, damages, and reasonable costs arising from your use of the service, your content or material, your breach of these terms, or your violation of any law or third-party right.

13. Changes to these terms

We may update these terms. If a change is material, we will give reasonable notice, such as by email or a notice in the product, before it takes effect. Continuing to use the service after the effective date means you accept the updated terms. If you do not accept them, stop using the service and, where applicable, request a refund of unspent credits.

14. Governing law and contact

These terms are governed by the laws of Mexico, and the courts of Mexico will have jurisdiction, without prejudice to any mandatory consumer protections available to you where you live.
