How this service works
Machine-readable reports of observed RSL declarations, with signed evidence and explicit payment terms.
Output
A JSON report containing: the rights decision (ALLOW_DECLARED, DENY_DECLARED, LICENSE_REQUIRED, or UNKNOWN), the number of RSL declarations found, the purpose and resource echoed back, a cryptographically signed evidence payload (Ed25519), a delivery proof, a legal_clearance boolean, and a payment settlement record showing the on-chain transaction for the $0.02 USDC charge.
Example use cases
Pre-training data rights check
“I want to train my model on content from https://news.example.com/story/12345 — can you run a rights check to see if AI training is declared as allowed, using a commercial user class and a fresh lookup?”
AI search indexing compliance
“Before my search crawler indexes https://blog.example.org/post/ai-future, verify whether the site declares permission for AI indexing, for commercial use, and give me the signed evidence report.”
Publisher rights audit for AI input pipeline
“Check whether https://research.example.edu/paper/456 allows AI input use under a non-commercial education context — I need the declared decision and any evidence of the RSL declarations.”
Technical details
Endpoint
POSThttps://api.getacqpath.com/v1/rights/preflight/x402?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a machine-readable, cryptographically attested record of whether a specific web resource has declared permissions for a given AI or search use case. It is especially valuable when legal defensibility matters — the signed evidence and on-chain payment settlement create an audit trail. Prefer it over informal scraping or manual robots.txt checks when you need structured ALLOW/DENY decisions tied to RSL declarations, particularly for commercial AI training or indexing pipelines that require compliance documentation.
Side effects
- Resource URL not on a reviewed origin — rejected with validation error
- max_total_micro below 20000 — budget too low error
- Invalid geo code (not ISO 3166-1 alpha-2) — schema validation failure
- Resource URL contains query string, fragment, credentials, or IP literal — rejected
- Purpose or user_class not matching allowed enum values — validation error
- Network or signing service unavailable — server error with no evidence returned
- Freshness window exceeded before response delivered — stale result or retry required
