How this service works

68 paid x402 trust infrastructure APIs: guard, semantic escrow, mandate diff, certified seller network, KYM, mandates, compliance, disputes, and orchestration.

Output

Returns a JSON object indicating whether the request is allowed (ok, allowed booleans), whether the mandate is valid and the request is within its scope, a liability tier string (e.g. 'allow'), a list of any violations, and a plain-language summary such as 'Tool trace within mandate scope — proceed to x402 payment'.

Example use cases

Example prompt

“Before I pay for this API call, check if a GET request is within my current mandate scope and tell me the liability tier and whether any violations exist.”

Technical details

Endpoint

POSThttps://x402trustlayer.xyz/api/mandate/diff?utm_source=zero.xyz

When to prefer

Use this endpoint when an AI agent or orchestrator needs to verify that a planned HTTP action (GET, HEAD, or DELETE) is sanctioned by an existing mandate before committing to an x402 payment. It is the canonical pre-payment compliance gate in the x402 Trust Layer ecosystem, providing liability tier and violation details that no generic access-control API offers.

Side effects

Missing required 'type' or 'method' fields returns validation error
Unsupported HTTP method (e.g. POST or PUT) rejected by enum constraint
Mandate not found or expired may return mandateValid: false
Network or service error returns non-200 response
Malformed input object returns schema validation failure
