Can I use this URL for RAG?
Preflight a source before adding it to a retrieval corpus. Later model use may need a separate ai-input check; do not silently buy both.
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
Preflight a source before adding it to a retrieval corpus. Later model use may need a separate ai-input check; do not silently buy both.
Use a canonical URL from the live supported-origin list. Coverage does not guarantee a billable or permissive result.
Request without payment
POST https://api.getacqpath.com/v1/rights/preflight with {resource,purpose,tier:"fresh",max_total_micro:"20000"}. A prepared 402 includes price/network/asset and the required private request binding. Empty POST is discovery-only. HTTP 200 with available:false and charge_micro:"0" is not a purchased report. There is no AcqPath account, API key or operator token.

ALLOW_DECLARED is observed evidence, not permission. DENY_DECLARED and LICENSE_REQUIRED require a hold or applicable license review. UNKNOWN stays UNKNOWN. No legal advice, legal clearance, ownership verification or license acquisition. HTTP 403 is not bypassed.
