A dataset URL is not a training-rights record

Why this evidence matters

Before training ingestion, document available machine-readable declarations for ai-train. Missing evidence never authorizes model training.

A source URL and event time alone may not preserve what the site exposed at observation time. AcqPath records the result and uncertainty for review, not a licence or legal clearance.

Rights Gateway: select the paid operation

LIVE Base USDC pricing: Secure Preflight 0.02 fresh / 0.05 deep per prepared settled report; Ingestion Gate 0.04 + 0.02 per distinct URL fresh or 0.06 + 0.04 per URL deep (1–4 eligible public HTTPS URLs); Revalidation 0.03 fresh / 0.06 deep. Stock x402 stays fresh-only 0.02 and reviewed-only. No new subscription, prepaid, API-key billing or invoicing plan is active.

A Secure Preflight may offer a disclosed paid UNKNOWN or no-declaration diagnostic after meaningful public-source observation. An outage with no usable source observation, invalid URL or exhausted safety budget is not billable Preflight. Gateway pricing covers a bounded observation attempt after verified authorization. UNKNOWN never authorizes content use.

SUPPORTED SECURE MODE: tested official TypeScript/Node x402 2.25.0 and Python x402 2.22.0 with the AcqPath SIWX adapter on /v1/rights/preflight; unchanged signer and random nonce, recommended when payer-signed request binding is required. SUPPORTED STOCK WIRE MODE: the same official stock clients without SIWX, custom nonce, signer or buyer hook on /v1/rights/preflight/x402, fresh only, 0.02 USDC. Stock binds one request atomically at first valid use; it does not sign the POST body in advance. Zero-config compatibility outside this fixed stock endpoint, stock SIWX-only hooks, Payments MCP and generic paid proxies are not supported by this integration.

When to call

Use ai-train before including selected source content in training preparation. AcqPath does not audit an entire dataset or acquire training licenses.

Deduplicate by canonical URL, purpose and context. Request new evidence only when your freshness policy requires it.

Input and purchase

Check live coverage → call POST /v1/rights/preflight through the AcqPath SIWX adapter → verify the prepared signed offer → preserve the unchanged official payment authorization privately → complete SIWX prebinding/authorization → receive the verified report. Use the same operation ID, input and private store after ambiguity; never create a replacement payment.

Decision and retry

UNKNOWN, missing declarations, unsupported origins and LICENSE_REQUIRED do not authorize use. A report records observed RSL declarations; it is not a license or legal clearance.

Verify all evidence and use one durable purchase ID. Resume an existing checkpoint after ambiguity; never create a replacement charge blindly.
