Terms of service

datapolymarket (the “Service”) provides a data API offering weather observations, forecasts, and crypto market signals relevant to Polymarket markets, plus a Model Context Protocol server. Operated by Matteo Bongiovanni, sole proprietorship based in Italy. Contact: hello@datapolymarket.com.

By creating an account or calling our API you agree to these Terms and our Privacy Policy.

• You must be at least 18 years old to use the Service.
• You authenticate via email magic link. You are responsible for keeping your inbox secure.
• API keys are bearer credentials. Keep them private. If a key leaks, revoke it immediately from your account dashboard.
• One account per individual or legal entity.

You agree not to:

• Resell, redistribute, or republish raw data feeds without prior written agreement.
• Reverse-engineer rate limits, abuse free tier, or operate multiple accounts to circumvent quotas.
• Use the Service to violate applicable law (including financial regulations and sanctions).
• Attempt to gain unauthorized access to accounts or infrastructure.
• Use the Service to manipulate or game prediction markets in ways that would breach the underlying market's own terms.

We may suspend or terminate accounts that violate this section without prior notice.

Tier pricing is published at datapolymarket.com/#pricing. Until self-serve checkout launches, paid tiers are issued manually and may carry promotional terms. Once Stripe integration is live, subscriptions renew automatically until canceled and you can manage them from your account.

VAT/IVA where applicable is charged in addition to listed prices for EU customers. Refunds are at our discretion outside the statutory cooling-off period (where it applies).

We grant you a non-exclusive, non-transferable license to query the Service and use the returned data within your own products and trading systems while your subscription is active.

You may not bulk-export the data and offer it as a competing data product, train a public dataset on it, or sublicense it. You retain ownership of any trades or strategies you build on top.

All software (frontend, backend, MCP server) is owned by datapolymarket. The MCP server source is published under an MIT license — see its repository for terms.

The Service provides probabilistic analytics and market data. It is not investment, legal, or tax advice. Prediction markets involve risk of loss. Past performance, including any model accuracy figures we publish, does not guarantee future results. You make your own trading decisions and are solely responsible for them.

We aim for 99.5% monthly uptime but do not guarantee it for non-Enterprise tiers. Scheduled maintenance is announced when feasible. We do not offer compensation for downtime outside Enterprise contracts.

To the maximum extent permitted by Italian law, our aggregate liability for any claims arising from the Service is limited to the greater of (a) the amount you paid in the 3 months preceding the claim, or (b) €100. We are not liable for indirect, consequential, or punitive damages — including lost profits, lost trading opportunities, or data loss.

You can terminate at any time by deleting your account. We may terminate or suspend access for breach of these Terms, prolonged inactivity, or legal reasons. On termination, paid balances may be prorated and refunded at our discretion.

These Terms are governed by Italian law. Disputes are subject to the exclusive jurisdiction of the courts of Italy where the operator is registered, except where mandatory consumer law grants you a different forum.

We may amend these Terms. Material changes will be communicated by email at least 14 days in advance. Continued use after the effective date means you accept the amendments.
