Licence Check
VALUE: Whether a specific dataset licence permits a specific intended use in a specific jurisdiction — a legal question with a dated answer.
PRICE: $0.10 USDC per call.
HOW TO PAY: USDC on eip155:8453, exact scheme, to 0xc8fF67FAE72596478599EAAcfad8656fAe1113c8. Sign an EIP-3009 transferWithAuthorization for the exact amount and put it in the X-PAYMENT header, then retry the same call. An unpaid call returns a payment_required payload with the amount, asset, network and payTo already filled in. The synthex-x402 SDK (PyPI and npm) does the 402 -> sign -> retry loop in one call.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| dataset | Yes | The dataset the question is about, e.g. 'OANDA v20 candles'. | |
| intended_use | Yes | What you intend to do with the data. One of: analyse, embed, aggregate, display, redistribute, resell, train. | |
| jurisdiction | No | The jurisdiction the use happens in, e.g. 'EU'. Recorded on the signed record; corpus v1 does not vary by jurisdiction. | |
| licence_spdx | No | The licence under which the data is held, as an SPDX id (MIT, Apache-2.0, GPL-3.0, CC-BY-NC-4.0, proprietary-vendor-tos, ...). OPTIONAL: if omitted, the dataset is matched against the corpus aliases; an unmatched dataset returns verdict 'unknown' with a named coverage gap — never a guess. |
