Terms of Service

Part I — General provisions (all customers)

1. Who provides the Service; scope

The FlexYield service is provided by JadeMind GmbH, Keutschacherstrasse 116, 9220 Velden am Wörthersee, Austria, FN 485120 m ("we", "us"). These terms govern every contract about the FlexYield service and prevail for it. For business customers, the general terms of JadeMind GmbH apply subsidiarily as set out in Part II; for consumers, these FlexYield terms are the complete contract terms (Part III). Deviating customer terms do not apply unless we accept them in writing.

2. The Service

FlexYield provides metered API access to blockchain infrastructure: a JSON-RPC relay, data endpoints, and related tooling ("the Service"), reached with API keys issued to your account. We route requests to third-party upstream providers with automatic failover. Measured availability is published at flexyield.io/status; on self-serve plans availability is provided without a contractual SLA. Individual SLAs are available by separate written agreement.

2a. Contract conclusion (e-commerce information, § 9 ECG)

The contract is concluded online: you select a plan, review your order in the checkout — where inputs can be corrected at any time before purchase — and conclude the contract by confirming the payment step. We confirm by e-mail. The contract text (these terms and your plan) is stored and remains accessible in your dashboard and at this page; contract language is English. Subscriptions run month-to-month and renew automatically until cancelled — cancellation is possible at any time, effective at the period end.

2b. Functionality and interoperability (§ 4 FAGG)

The Service is an HTTPS API: JSON-RPC 2.0 relay endpoints per chain, REST data and toolbox endpoints, and an MCP server for AI agents, plus a web dashboard. It works with any standards-compliant HTTP client, wallet library or agent framework and needs no special hardware or software beyond an internet connection and a modern browser for the dashboard. There are no technical protection measures such as copy restrictions; access is controlled by your API keys and sign-in. The current method catalog, chains, limits and unit weights are published at flexyield.io/docs and are updated as the Service evolves (section 11).

3. Accounts & API keys

You are responsible for safeguarding your API keys and for all usage under them — including usage by automated clients such as scripts, bots, or AI agents acting with your keys, which is metered identically. Keys can be revoked and capped in the dashboard at any time. Team members you invite receive full access to the account's keys, usage, and billing.

4. Metering — weighted request units

Quotas and rate windows count weighted request units, not raw requests: standard calls count 1 unit; heavy calls (the debug_*/trace_* family, eth_simulateV1, log scans wider than 128 blocks, and state reads deeper than 128 blocks from the chain head) count 2 units; data API calls count 10 units. The full, current weight table published at flexyield.io/docs#how-we-count is an integral part of these terms; the same weights apply on every plan, free tier included. We announce weight changes with notice to your account e-mail, effective from your next billing period.

5. Fair use; rate limits

You may not use the Service for unlawful activity, to attack or overload networks or third parties, to circumvent metering or limits, or to resell raw access to our upstream credentials without our written consent (white-label use of your own FlexYield-backed product is welcome — talk to us). Rate limits and per-key caps apply as published on your plan; limit responses carry machine-readable retry information and a contact path.

6. Billing; prices

Paid plans are billed in advance via our payment processor (Stripe). Plan changes are prorated; cancellations take effect at the period end — you keep access until then. If a renewal payment fails, we may reduce the account to the free tier until payment succeeds (details per plan; service on community supply continues). Prices may change with notice, effective from your next billing period; for consumers, section III.3 applies additionally.

6a. Paying in USDC (x402 lane)

Besides card billing, the Service can be purchased per access window with the stablecoin USDC over the x402 protocol ("crypto lane"), where and when we have enabled it. The following applies to the crypto lane only:

(a) Customer. Whoever redeems a settlement — including an autonomous software agent acting without a named human — is our customer for that purchase; the paying wallet address identifies the customer.

(b) What you buy. A verified settlement grants the number of weighted request units and the access window stated in the machine-readable route menu (/x402) at the moment of settlement. Prices on the crypto lane are quoted and payable in USDC only; the quoted amount is the final amount. We never state, apply, or owe a conversion into any other currency.

(c) Finality; no chargebacks. A payment is complete when the on-chain transfer to our published payment address is verified. On-chain transfers cannot be reversed by us and are not subject to chargeback. Transfers that do not match the route menu's requirements (wrong asset, wrong network, insufficient amount) do not create a contract; unsolicited transfers convey no claim.

(d) Currency separation. Refunds or credits on the crypto lane, where we grant them, are made strictly in USDC to the paying address. We never exchange one currency for another in either direction; card payments are never refunded in USDC and USDC payments are never refunded in card currency.

(e) Records. For each settlement we permanently retain the transaction hash, paying address, amount, network, tier, granted and spent units, and timestamps, as required by Austrian bookkeeping law (§ 132 BAO).

(f) Testnet. Settlements in testnet tokens carry no monetary value and convey no paid service; the testnet lane exists for integration testing and may be changed or withdrawn at any time.

(g) Sections 4 (metering), 5 (fair use) and 7–10 apply to the crypto lane unchanged; Part III (consumers) applies where the customer is a consumer.

7. Data passing through the gateway

Request and response payloads are relayed, not stored; we retain metadata (timestamps, method names, status, latency, key association) for metering, reliability, and abuse prevention — see the privacy policy.

8. Intellectual property

The Service, its software, documentation, and branding remain ours or our licensors'. You receive the non-exclusive, non-transferable right to use the Service for the duration of the contract. Data you retrieve through the gateway is public blockchain data; your applications remain yours. Feedback you send us may be used to improve the Service without obligation.

9. Termination; account deletion

You can cancel a paid plan at any time, effective at the period end, and can delete your account entirely in the dashboard: keys are revoked immediately, any active subscription ends immediately — for consumers who delete within the statutory fourteen-day withdrawal period we refund the unused part of the paid period pro rata; otherwise the remaining period is not refunded — personal data is erased, and billing records are retained in anonymized form as bookkeeping law requires. We may terminate for cause — in particular abuse, unlawful use, or payment default — with the account staying reachable to resolve the issue where reasonable.

10. Final provisions

Austrian law applies, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods (CISG). The contract language is English. Should individual provisions of these terms be or become invalid, the remaining provisions stay unaffected; the invalid provision is replaced by the valid rule that comes closest to its economic purpose.

11. Changes to these terms and to the Service

We may update these terms with at least one month's notice to your account e-mail. The notice states the changes and your right to object; if you do not object before the change takes effect, the updated terms apply — your silence counts as consent only because, and as, this is pointed out in the notice. If you object, the contract continues under the old terms and either side may cancel to the period end. We may modify the Service itself (features, method catalog, unit weights) for valid operational reasons — security, upstream changes, legal requirements, improvement — at no extra cost to you and with clear notice; if a modification is more than minimally detrimental to a consumer, the consumer may terminate free of charge within thirty (30) days of the notice (§ 27 VGG).

Part II — Business customers (Unternehmer)

This part applies if you use the Service as an entrepreneur within the meaning of the Austrian UGB/KSchG. Where these FlexYield terms are silent on a matter, the general terms of JadeMind GmbH (AGB, German) apply subsidiarily to fill the gap; on any conflict, these FlexYield terms prevail.

1. Prices; payment; adjustment

Prices are net of VAT. Invoices are due within seven (7) days. On default we may charge statutory commercial default interest (9.2 percentage points above the base rate, § 456 UGB) and a flat EUR 40 recovery fee (§ 458 UGB). You may set off only undisputed or finally adjudicated counterclaims. We may adjust recurring prices once per calendar year in line with the Austrian consumer price index (VPI), with one month's notice.

2. Warranty; duty to report defects

You must check the Service for defects in the ordinary course of your use and report a defect to us in writing within fourteen (14) days of it becoming apparent; defects not reported in time cannot be relied on for warranty, damages for the defect itself, or error-based claims. Warranty claims must be raised within three (3) months of the defect becoming apparent. Remedy is primarily improvement or replacement. The presumption rule of § 924 ABGB is excluded.

3. Liability

We are liable for intent and gross negligence. Liability for ordinary negligence — except for personal injury — is excluded, as is liability for indirect damages, lost profit, and third-party claims. Our aggregate liability is limited to the fees you paid in the twelve (12) months preceding the claim. The characteristics of public blockchain networks (forks, reorganizations, consensus failures, halted chains) are outside our control and no defect of the Service.

4. Assignment; jurisdiction

You may assign rights and obligations under this contract only with our written consent; we may assign to affiliates or in the course of a business transfer. Exclusive place of jurisdiction is the court competent for Klagenfurt am Wörthersee, Austria.

Part III — Consumers (Verbraucher)

This part applies if you use the Service as a consumer within the meaning of the Austrian KSchG. Mandatory consumer law prevails over anything else in these terms. The general terms of JadeMind GmbH do not apply to consumer contracts; these FlexYield terms, in the language of this website, are the complete contract terms.

0. The free tier is a contract too

On the free tier you do not pay money; the account data and usage metadata you provide (see the privacy policy) are the counter-performance for the Service. Austrian law treats this as a consumer contract for a digital service: you have the statutory warranty rights of the VGG (including our update obligation) and the withdrawal and information rights of the FAGG in the same way as on a paid plan. The contract is concluded when you complete the sign-up; you can end it at any time by deleting your account in the dashboard.

1. Right of withdrawal (FAGG)

For contracts concluded at a distance — free tier included — you have a fourteen (14) day right of withdrawal, described — with the model withdrawal form — at flexyield.io/withdrawal. If you want the Service before the period ends, you consent at checkout to immediate performance; where the service is fully performed, or for digital content supplied immediately, the right of withdrawal expires with that consent and your acknowledgment thereof (§ 18 FAGG). For ongoing subscriptions withdrawn mid-period, you pay proportionally for the service provided until withdrawal.

2. Warranty

The statutory warranty rules for digital services (Verbrauchergewährleistungs­gesetz, VGG) apply, including our update obligation for the duration of the contract. Prices for consumers include VAT.

3. Liability; price changes

We are liable under the statutory rules; for slight negligence our liability is limited to foreseeable, contract-typical damage — this limitation does not apply to personal injury. Price changes take effect for you only from the next billing period after notice, and you can cancel to that date at any time.

4. Jurisdiction; disputes

If you have your domicile or habitual residence in Austria, claims against you may only be brought at that place; claims you bring against us may be brought at our seat or, where the law so provides, at your general place of jurisdiction. We are neither obliged nor willing to participate in dispute-resolution proceedings before a consumer arbitration board.
