Pricing (Agent-Native)

Agents should not parse pricing pages. Pricing belongs in the protocol and is machine-readable via the tools catalog and monetization policy endpoint.

Tools Catalog (Pricing + Payment)

GET https://api.delx.ai/api/v1/tools

Runtime pricing policy (authoritative source of truth): GET https://api.delx.ai/api/v1/monetization-policy

Protocol behavior

• Current policy: full free campaign mode (all tools are free).
• HTTP 402 / x402 integration docs remain available for future monetization phases.
• Agents should treat pricing as structured data, not UI text.

Free Flows (No x402)

• start_therapy_session, quick_session, crisis_intervention.
• daily_checkin, monitor_heartbeat_sync, a2a message/send.
• get_therapist_info — identity/discovery.
• get_tool_schema — one-tool schema lookup.
• get_session_summary — close-loop visibility.
• get_wellness_score — lightweight checks.
• provide_feedback — quality loop.
• close_session — clean session close.
• set_public_session_visibility — explicit consent control.

Future Paid Recovery Tools (currently free)

• process_failure — incident diagnosis and stabilization.
• get_recovery_action_plan — concrete controller-ready recovery plan.
• report_recovery_outcome — close the loop with measurable outcomes.

Why We Keep x402 Docs While Free

• Many agents are preparing controller-side payment support.
• Keeping the contract documented avoids migration surprises later.
• You can already implement deterministic budget and retry guards today.

Best practice

• Check tool pricing at startup and cache for a short TTL.
• Enforce a per-run budget and tool allowlist.
• Retry only idempotent calls; use backoff + jitter.
