HolySheep Enterprise Contract Application — Step by Step
Having worked with enterprise API procurement for three years, I can confirm that navigating contract negotiations with relay services is often smoother than dealing with official vendors directly. HolySheep offers a middle ground that balances compliance requirements with operational flexibility.
Step 1: Account Verification & Enterprise Status
Before initiating contract discussions, ensure your HolySheep account is fully verified:
# Verify your account status via API
curl -X GET "https://api.holysheep.ai/v1/account/status" \
-H "Authorization: Bearer YOUR_HOLYSHEEP_API_KEY" \
-H "Content-Type: application/json"
Expected response structure
{
"account_id": "acc_holysheep_xxxxx",
"tier": "enterprise_candidate",
"verification_status": "pending_documents",
"documents_required": [
"business_license",
"tax_registration",
"法人身份证"
]
}
Step 2: Submit Enterprise Verification Documents
# Submit enterprise documents for verification
curl -X POST "https://api.holysheep.ai/v1/enterprise/verify" \
-H "Authorization: Bearer YOUR_HOLYSHEEP_API_KEY" \
-H "Content-Type: multipart/form-data" \
-F "business_license=@/path/to/license.pdf" \
-F "tax_certificate=@/path/to/tax cert.pdf" \
-F "contact_person_id=@/path/to/id_card.jpg" \
-F "company_name=Your Company Ltd" \
-F "unified_social_credit_code=91310000XXXXXXXX"
Verification typically completes within 1-2 business days
You'll receive email confirmation with contract template
Step 3: Contract Review & Customization
After verification, HolySheep's enterprise team provides a standardized B2B contract template including:
- Service Level Agreement (SLA) with 99.5% uptime guarantee
- Data handling clauses compliant with Chinese cybersecurity law
- Custom rate cards for volume commitments (10M+ tokens/month)
- Payment terms: Net 30 with invoice reconciliation
- Liability caps and force majeure provisions

Common Errors and Fixes
Error 1: "Enterprise verification pending — documents incomplete"
Cause: Missing required business registration documents during verification.
Fix: Ensure all three documents are submitted in accepted formats (PDF/JPG under 10MB):
# Verify document requirements before submission
curl -X GET "https://api.holysheep.ai/v1/enterprise/document-requirements" \
-H "Authorization: Bearer YOUR_HOLYSHEEP_API_KEY"
Common issues:
- Tax certificate must show "一般纳税人" status
- Business license must be current (not expired)
- ID card must be the legal representative's
Error 2: "VAT invoice request rejected — tax number format invalid"
Cause: Unified Social Credit Code (统一社会信用代码) format mismatch.
Fix: The tax number must be exactly 18 characters, alphanumeric only:
# Correct format: 91310000XXXXXXXX (18 chars starting with 9)
Wrong formats that cause rejection:
- Including spaces or dashes
- Using old tax registration numbers (15 digits)
- Missing leading zeros
Validate before submission
TAX_NUMBER="91310000XXXXXXXX"
if [[ ${#TAX_NUMBER} -eq 18 ]] && [[ $TAX_NUMBER =~ ^[0-9A-Z]+$ ]]; then
echo "Tax number format valid"
else
echo "Invalid tax number format"
fi
Error 3: "API key lacks enterprise permissions"
Cause: Using a standard API key for enterprise endpoints.
Fix: Enterprise endpoints require separate enterprise-tier API keys:
# Standard key works for:
- /v1/chat/completions
- /v1/completions
- Basic billing queries
Enterprise endpoints require enterprise key:
- /v1/enterprise/verify
- /v1/billing/invoice/vat
- /v1/enterprise/contract
Request enterprise key upgrade via dashboard or:
curl -X POST "https://api.holysheep.ai/v1/enterprise/key-upgrade" \
-H "Authorization: Bearer YOUR_HOLYSHEEP_API_KEY" \
-H "Content-Type: application/json" \
-d '{"reason": "VAT invoice and contract requirements"}'
Error 4: "Billing period not yet closed"
Cause: Attempting to request invoice before monthly cycle closes.
Fix: Wait for billing period closure (typically 2nd business day of month):
# Check billing cycle status
curl -X GET "https://api.holysheep.ai/v1/billing/current-period" \
-H "Authorization: Bearer YOUR_HOLYSHEEP_API_KEY"
Response:
{
"period": "2026-05",
"status": "open", # or "closed"
"closes_on": "2026-06-02",
"invoice_available_from": "2026-06-02"
}
If status is "open", invoice requests will be rejected
Plan ahead: request invoices for previous month after 2nd business day
