How this service works
Compare requested agent tools with an explicit least-privilege allowlist. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization…
Output
A deterministic machine-readable JSON object indicating which of the requested tools are permitted (present in the allowlist) and which are denied (not in the allowlist), along with a summary of the audit outcome. Results are advisory and stateless — no data is retained.
Example use cases
Pre-deployment agent tool gating
“Before deploying this new agent to production, check its tool requests against our approved list. Allowed: ['read_crm','send_notification','log_event']. Requested: ['read_crm','send_notification','write_crm','delete_user']. Which tools are outside the allowlist?”
Enterprise security preflight for data pipeline
“We're about to kick off a data pipeline agent and need a permission audit first. Our allowlist is ['query_warehouse','read_s3','write_report'] and the agent is requesting ['query_warehouse','read_s3','drop_table','write_report','call_external_api']. Flag anything that isn't permitted.”
Least-privilege enforcement in multi-agent workflow
“Run a tool permission audit for the sub-agent in our orchestration workflow. The approved tools are ['fetch_weather','format_response'] and it's asking for ['fetch_weather','format_response','send_sms','access_payments']. I need to know exactly which requested tools are denied before we let it proceed.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/tool-permission-auditWhen to prefer
Use this endpoint when you need a fast, stateless, deterministic preflight check to enforce least-privilege tool access for an AI agent before it reaches production. Prefer it over custom authorization logic when you want a cheap, consistent, machine-readable audit result that can be embedded as a bounded step inside a larger agent workflow without side effects or data retention.
Side effects
- Missing or empty 'allowed' array — may return an error or deny all requested tools
- Missing or empty 'requested' array — may return an empty result or vacuous pass
- Malformed array input — returns a validation or schema error
- Network or payment failure — x402 payment on Base may fail if wallet is underfunded or network is congested
