The Yield Agentic Hub (YieldAgentX402) is a custody-free, policy-gated, receipt-backed execution layer for AI agents, enabling secure and verifiable financial and business operations across 18 blockchain networks.

Discovery & Platform

• yax_get_capabilities: Explore all available tools, chains, rate limits, and configs — no API key required

Execution & Payments

• yax_submit_approval: Approve or deny pending policy approval tokens

• yax_control_workflow: Stop or resume orchestration workflow runs

• yax_audit_compliance: Audit agent activity against policy rules and generate Filecoin-anchored compliance reports

Receipts & Verification

• yax_get_receipt: Fetch full signed receipts with policy results, TEE attestation, and Filecoin/BTFS proof CIDs

• yax_verify_receipt: Cryptographically verify a receipt's signature and confirm its Filecoin anchor

• yax_list_runs: View recent agent runs filtered by outcome (approved/denied/escalated)

Wallet & Finance

• yax_get_wallet_status: View USDC balance, spend cap, and remaining cap

• yax_forecast_cash_flow: Generate week-by-week cash flow forecasts across base, optimistic, and pessimistic scenarios

• yax_collect_ar_invoices: Analyze overdue invoices by aging bucket and send escalating follow-up emails

CRM & Sales Automation

• yax_enrich_lead_data: Parse raw emails, forms, or webhooks into structured CRM-ready contact records

• yax_build_email_sequence: Generate personalized multi-step cold email campaigns for prospect lists

• yax_monitor_churn_risk: Identify at-risk customers by usage/payment patterns and draft re-engagement emails

Security & Attestation

• yax_get_attestation: Verify the Intel TDX TEE enclave is operational with a verifiable mrEnclave hash before high-value actions

Under the hood, every execution is backed by HMAC-SHA256 signed receipts and dual Filecoin/BTFS anchoring for tamper-proof permanent storage. SDKs are available for TypeScript, CrewAI, and LangChain.
