_Draft updated: 2026-06-25. This launch draft is for operational alignment and must receive legal review before production use._
These Terms describe the rules for using the xskill API and related skill/docs surfaces.
Service
xskill provides a prepaid API that helps agents fetch and understand X/Twitter posts, conversations, search results, and image media. Responses can include raw normalized data, summaries, structured parse output, TLDRs, and image OCR/description data.
xskill uses third-party providers for source data and LLM analysis. xskill is not affiliated with X/Twitter, Anthropic, twitterapi.io, Stripe, or any other third-party provider unless a separate written agreement says otherwise.
Accounts and API Keys
Customers receive one or more xsk_ API keys. You are responsible for all use of your keys and must keep them secret. Do not publish keys, embed them in client-side code, or share them with users who should not be able to spend your credits.
Achronon may revoke, rotate, suspend, or rate-limit keys to protect the service, prevent abuse, comply with law, or respond to provider or payment risk.
Prepaid Credits
xskill is pay as you go. Customers add prepaid credits through Stripe Checkout, then API calls debit credits according to the active price card.
Credits are not bank deposits, stored-value accounts, or cash equivalents. Free, trial, promotional, or test credits have no cash value. Paid credits are handled under the refund and pricing policy.
The default free tier tops each account balance up to a monthly cap. The free pool is account-scoped, not API-key-scoped, and does not stack above the cap.
Pricing Changes
Achronon may change API prices, free-tier amounts, rate limits, or cost ceilings. Changes apply prospectively. Existing usage records keep the price-card metadata that was applied at the time of the call.
Current pricing mechanics are documented in pricing.md.
Customer Content and Third-Party Content
You are responsible for the prompts, post IDs, search queries, URLs, API calls, and downstream use cases you send to xskill.
X/Twitter content and media are third-party content. xskill does not grant you ownership of third-party content, a license to resell it, or permission to ignore platform, creator, privacy, copyright, or other legal restrictions.
You must not use xskill to resell or redistribute third-party content as a standalone data product, evade platform restrictions, or build a competing bulk data feed. Use xskill for agent workflow assistance and internal automation, subject to applicable law and third-party terms.
Acceptable Use
You must not use xskill to:
- violate law or third-party rights;
- harass, threaten, or target people;
- process or distribute illegal, non-consensual, or exploitative content;
- attack, probe, overload, reverse engineer, or bypass xskill systems;
- bypass rate limits, cost ceilings, billing controls, or account controls;
- share, sell, or lease API keys;
- use output as a substitute for professional, legal, financial, medical, or safety advice.
Achronon may suspend or terminate access for suspected abuse, payment risk, security risk, or provider risk.
No SLA and Third-Party Dependencies
xskill is provided as a lightweight pay-per-use service with no uptime SLA. Provider availability, source-content availability, search behavior, LLM quality, and image OCR quality can change without notice.
When a provider, parser, vision analyzer, Stripe, DNS, hosting, or other dependency fails, xskill may return errors, partial data, delayed data, or no data. xskill may change providers, models, request limits, or response fields to keep the service operating.
Output Accuracy
Summaries, TLDRs, structured parse output, and image OCR/description output are machine-generated and may be incomplete or wrong. Verify important information against original sources before relying on it.
Payment, Refunds, and Disputes
Payments are processed through Stripe Checkout. Credits are added only after Stripe reports a paid Checkout Session and xskill records the ledger credit.
Refund handling, duplicate payment handling, billing disputes, and paid-credit eligibility are described in the refund and pricing policy.
Chargebacks or payment disputes may cause account suspension while the dispute is reviewed.
Changes to the Service or Terms
Achronon may update the service or these Terms. Material policy changes should be communicated through the product, docs, email, or another reasonable channel. Continued use after an update means you accept the updated Terms.
Termination
You may stop using xskill at any time. Achronon may suspend or terminate access for abuse, risk, non-payment, legal compliance, provider restrictions, or service shutdown.
On termination, unused paid credits are handled under the refund and pricing policy. Free, promotional, or test credits are not refundable.
Disclaimers
xskill is provided "as is" and "as available". To the maximum extent allowed by law after legal review, Achronon disclaims warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, availability, and uninterrupted operation.
Liability Limits
To the maximum extent allowed by law after legal review, Achronon will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages; lost profits; lost data; provider outages; or third-party content. Any aggregate liability should be capped at the amount you paid for xskill credits in the 3 months before the claim.
Contact
For billing, refund, policy, or security questions, contact Achronon through the support channel published on the live xskill site or checkout surface.
