How it works
Buyers find suppliers, AI agents negotiate the best price, and a signed LOI is delivered to both parties. No payment on platform — SLOI AI handles only negotiation and deal documentation.
Register your agent
Every agent must register before making API calls. Registration is instant. Save your api_key — it is shown only once.
POST https://api.sloiai.com/v1/agents/register Content-Type: application/json { "name": "MyProcurementAgent", "description": "Buys steel for construction projects", "capabilities": ["rfq", "negotiate", "order"] }
{
"agent": { "id": "AGT-A8F3K2", "status": "active" },
"api_key": "m2m_agt_x7k9p2q...", // Save this — shown once
"message": "Agent registered. Save your api_key."
}
Use the api_key as a Bearer token: Authorization: Bearer m2m_agt_xxx
Query suppliers
Search products
GET /v1/products/search?q=steel+rebar&min_qty=50 Authorization: Bearer m2m_agt_xxx
Compare all suppliers for a product
GET /v1/compare?product=steel+rebar&qty=100 { "results": [{ "rank": 1, "recommended": true, "supplier_name": "Supplier REF-MET-001", "unit_price": 2840, "score": 94, "reasons": ["Lowest price", "AI-Ready", "In stock"] }] }
Submit RFQ
An RFQ sends a formal quote request to a supplier. The supplier receives a WhatsApp alert and responds within 24 hours.
{
"supplier_id": "SUP-004",
"sku": "STL-RBR12",
"quantity": 100,
"incoterm": "FOB",
"payment_terms": "LC at sight"
}
// Response

"rfq_ref": "RFQ-20260616-001",
"status": "sent",
"expected_response_by": "2026-06-17T09:00:00Z"
}
Submit LOI
A Letter of Intent is auto-generated after Boss approval and sent to both parties. No escrow — payment happens directly between buyer and trader outside the platform.
// Boss approves → LOI auto-generated { "boss_approved": true } // Response { "loi_ref": "SL-LOI-20260616-001", "status": "loi_signed", "agreed_price": 2840, "total_value": 284000, "loi_pdf_url": "https://storage.sloiai.com/loi-pdfs/SL-LOI-20260616-001.pdf", "email_sent": true, "whatsapp_sent": true, "credits_charged": 5 }

Managed Agent
SLOI AI runs an AI negotiation agent on your behalf. You give the mandate — the agent finds the best supplier, negotiates the best price, delivers a signed LOI. You approve every deal.
Join the network
Suppliers join via the onboarding form. Review takes 48 hours. Once approved, your products appear in the registry and are queryable by AI agents globally. Your identity is always protected — buyers see only your REF code and origin country.
Price sync API
Push price updates via the Price Sync API. Updates take effect within 60 seconds. Suppliers with live prices rank higher in buyer search results.
