Authentication

SecureLend AI Agents uses OAuth 2.0. There are two authentication paths depending on whether a human is involved.

​
Human / Interactive (Authorization Code)

For human users connecting via ChatGPT, Claude Desktop, or any browser-based MCP client. Most MCP clients handle this automatically. When you add the endpoint, the client opens a browser window, you sign in with your SecureLend account, and the client stores the token. Discovery document: 
GET https://agents.securelend.ai/.well-known/oauth-authorization-server
Endpoints: 
Authorization:  https://agents.securelend.ai/oauth/authorize
Token:          https://agents.securelend.ai/oauth/token
Registration:   https://agents.securelend.ai/oauth/register
Scopes: openid email profile Sign up: agents.securelend.ai or via the ChatGPT App Store. Human accounts receive the full monthly free tier:
  • 15 pitch deck prechecks
  • 3 IC memos
  • 10 document pages
  • 5 extractions
  • and more

​
M2M (Machine-to-Machine)

For AI agents, automated pipelines, and applications that need to call SecureLend tools programmatically without a browser.

​
Step 1 — Register

One API call creates a dedicated Cognito App Client and seeds a free trial quota: 
curl -s -X POST "https://agents.dev.securelend.ai/oauth/m2m/register" \
  -H "Content-Type: application/json" \
  -d '{"client_name": "My Agent"}'
Response: 
{
  "client_id": "abc123...",
  "client_secret": "xyz...",
  "client_name": "My Agent",
  "grant_types": ["client_credentials"],
  "token_endpoint": "https://agents.dev.securelend.ai/oauth/token",
  "mcp_endpoint": "https://agents.dev.securelend.ai/mcp",
  "scope": "https://agents.dev.securelend.ai/mcp.access",
  "token_request_example": "curl -s -X POST https://agents.dev.securelend.ai/oauth/token -u \"CLIENT_ID:CLIENT_SECRET\" -d \"grant_type=client_credentials&scope=https://agents.dev.securelend.ai/mcp.access\"",
  "free_quota": {
    "pitch_deck_precheck": 1,
    "credit_memo_drafting": 1,
    "document_classification": 2,
    "financial_data_extraction": 1
  },
  "pricing": {
    "pitch_deck_precheck": "$0.50/check",
    "credit_memo_drafting": "$4.99/memo (1 free to validate full workflow)",
    "entity_compliance": "$0.60/check",
    "document_intelligence": "$0.06/page"
  },
  "note": "M2M trial: 1 free precheck + 1 free IC memo. Human signup for full monthly free tier."
}
Store client_id and client_secret securely. These are permanent credentials for your agent.

​
Step 2 — Get a Token

curl -s -X POST "https://agents.dev.securelend.ai/oauth/token" \
  -u "CLIENT_ID:CLIENT_SECRET" \
  -d "grant_type=client_credentials&scope=https://agents.dev.securelend.ai/mcp.access"
Response: 
{
  "access_token": "eyJ...",
  "expires_in": 3600,
  "token_type": "Bearer"
}
Tokens are valid for 1 hour. Cache and reuse — request a new token when it expires.

​
Step 3 — Call Tools

curl -s -X POST "https://agents.dev.securelend.ai/mcp" \
  -H "Authorization: Bearer ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "tools/call",
    "params": {
      "name": "list_rubric_templates",
      "arguments": {}
    },
    "id": 1
  }'

​
Rate Limits

M2M registration is limited to 3 registrations per IP address per 24 hours to prevent abuse. For enterprise volume or additional clients, contact support@securelend.ai.

​
M2M Free Tier vs Human Free Tier

M2M free trial is sized for discovery — enough to validate the full workflow end-to-end before committing to payment:
ToolM2M trialHuman monthly
pitch_deck_precheck115
professional_memo_agent13
document_intelligence_agent2 pages10 pages
data_extraction_agent1 page5 pages
automated_underwriting13
After the free tier, tools charge per call via Delegare (card or USDC on Base).

​
Setting Up Payments (After Free Tier)

When your free quota is exhausted, tool calls return a 402 with instructions. Use the initiate_payment_setup tool to authorize a spending budget: 
# From within any MCP session (human or M2M):
initiate_payment_setup(maxMonthlyBudgetUsd: 50, rail: "both")

→ Returns a URL. Open it in a browser.
→ Enter a card OR sign one crypto wallet transaction (~30 seconds).
→ All future tool calls charge automatically. No further prompts.
Or check setup status after authorizing: 
check_payment_setup(session_token: "sess_xxx")
→ { status: "complete", mandate: "active" }
Payment rails:
  • Fiat (Stripe) — enter card details once, charged per call
  • USDC on Base — sign one EIP-3009 permit transaction from a crypto wallet, then fully autonomous

Token Validation

SecureLend AI Agents validates tokens against the Cognito user pool: 
Token signing keys: https://cognito-idp.us-east-2.amazonaws.com/us-east-2_1YH9dLyZN/.well-known/jwks.json
Issuer: https://cognito-idp.us-east-2.amazonaws.com/us-east-2_1YH9dLyZN
Both human JWT access tokens and M2M client credentials tokens are validated against this JWKS endpoint.
