Can I crawl this URL? Keep crawl and AI use separate.
AcqPath does not offer a paid crawl-permission product. Evaluate actual downstream AI input, indexing, training or search declarations separately.
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.
Before crawling
Respect your crawler access, robots and site policy before retrieval. A rights report is not a robots.txt validator, permission grant or access-control bypass.
The existing free XML inspection path accepts a legacy crawl purpose, but it inspects supplied XML only; it does not fetch the URL and cannot establish usage rights.
Before ingestion
Once your crawler has a legitimately selected supported source, choose the actual paid purpose: ai-input, ai-index, ai-train or search.
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.
Hold uncertain sources
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.
