How this service works
Offline deterministic checks (no ML, no scraping) for business identifiers and rental due-diligence, paid per call via x402 (gasless EIP-3009 USDC on Base). Checksum-verifiable (IBAN, LEI, VAT, ABA, ISBN, SEDOL…) vs format-only (EIN, IFSC, SWIFT/BIC…) — every response returns a scope field. Non-custodial, signed receipts. First 3 calls/day free.
Output
A JSON object containing: verdict (clear, caution, or high-risk), a numeric risk_score, a band label (e.g. low/medium/high), a scope field indicating what was checksum-verifiable vs format-only, an array of flags raised, a human-readable summary, and a components breakdown of what was evaluated.
Example use cases
Tenant screening before lease signing
“I have a prospective tenant applying for my $1,500/month unit — name Sarah Kim, reported monthly income $3,800, and her employer's LEI is 254900OPPU84GM83MG36. Can you run a rental verdict on her and tell me the risk band and any flags?”
Landlord compliance identifier check
“Before I process this corporate rental application, can you verify the applicant's IBAN DE89370400440532013000 and their VAT number DE811128135 are valid, and give me a verdict on whether this looks clear or risky?”
Automated rental pipeline risk gate
“We're processing a batch of rental applications and need to screen applicant ID 7742 — rent requested is $2,200/month, stated income $5,500, ABA routing number 021000021. Run the rental verdict check and return the risk score and summary so we can decide whether to proceed.”

Endpoint
POSThttps://hcrb.in/v1/tools/rental-verdict/call?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, offline risk verdict on a rental applicant or need to validate business/financial identifiers (IBAN, LEI, VAT, ABA, ISBN, SEDOL, EIN, IFSC, SWIFT/BIC) without relying on ML models, external credit bureaus, or web scraping. Ideal when reproducibility, privacy, and signed audit receipts matter. At $0.05/call with the first 3 free daily, it suits both occasional landlord checks and high-volume automated rental pipelines.
Side effects
- Invalid or malformed identifier format returns a validation error with scope indicating format-only check
- Unsupported identifier type returns an error indicating the field is out of scope
- Missing required fields in the POST body returns a 400-level error
- Payment not included or insufficient — x402 payment header missing or underfunded causes a 402 Payment Required response
- After 3 free calls per day, unpaid calls are rejected with a 402 until payment is attached
