Kovo - Build Credit Fast: API integration & OpenFinance services

Deliverables checklist

• OpenAPI 3.1 specification for every Kovo endpoint we expose
• Protocol report covering token exchange, signing headers and the mobile certificate pinning workaround
• Runnable reference clients in Python (httpx) and Node.js (undici)
• Postman collection plus pytest / Jest assertion suites
• FCRA / Regulation V compliance memo and consent-event template

Engagement models

• Source-code delivery from $300 — runnable API source plus full documentation; you pay after the build is accepted.
• Pay-per-call hosted API — connect to our managed Kovo gateway and pay only for the calls you make. No upfront fee.
• Optional ongoing maintenance retainer for protocol drift, bureau format changes and CFPB rule updates.

1. Lender pre-qualification feed

An auto-loan or rental-application platform consumes a borrower's Kovo Installment Credit Builder schedule plus the latest FICO Score snapshot. The pre-qualification engine combines on-time-payment ratio with monthly score deltas to surface low-friction approvals — without forcing a hard pull. Maps to OpenFinance "consumer permissioned data" patterns.

2. Multi-bureau reconciliation

Because Kovo is one of the few products that reports to all four bureaus, integrators can pull the same monthly tradeline from each bureau's payload and reconcile discrepancies. The integration exposes a diff() view that flags missing rows on Innovis or stale balances on Equifax — a common feed for credit-repair tooling and dispute automation.

3. Identity-protection orchestration

Kovo bundles Max Credit Protection (up to $1M ID Fraud Insurance, underwritten by American Bankers Insurance Co. of FL). The webhook stream emits monitored breach hits and adverse credit events. A SOC playbook can route high-severity alerts into Splunk or PagerDuty, and an ITSM workflow can issue a security freeze through the same OpenData adapter.

4. Personal-finance dashboard sync

Apps such as YNAB, Monarch and Copilot can ingest the Installment Credit Builder ledger as a sub-account, and the FICO Score snapshot as a monthly net-worth metric. The integration produces an OFX-style feed plus a Plaid-compatible /accounts shim for legacy aggregators that have not yet adopted FDX.

5. Loyalty and referral attribution

Kovo's referral program ($30 per qualifying friend, lifetime rewards up to $1,225) generates per-event records that affiliate networks and CRM tools can reconcile. The integration exposes referrer_id, state, milestone and payout_eligible fields so finance teams can match channel attribution to real cash-back disbursements.

U.S. credit-data regulation

Credit-bureau feeds are governed by the U.S. Fair Credit Reporting Act (FCRA) and CFPB Regulation V (12 CFR Part 1022). Every Kovo integration we deliver assumes a permissible purpose, supports security-freeze handling, captures consent metadata for audit and respects the consumer's right to dispute. Late-2025 CFPB guidance on FCRA preemption and the December 2024 proposed rulemaking are tracked and reflected in the compliance memo we ship with the build.

Data minimisation and retention

• Field-level scopes (credit:read, score:read, alerts:read) so callers only request what they need.
• Default 30-day retention on raw bureau payloads, with hash-only retention of tradelines beyond that.
• Consent log captures purpose, scope, timestamp and the IP from which authorisation was granted.
• State-level alignment with the California CCPA / CPRA, Virginia VCDPA and Colorado CPA where applicable.
• Adverse-action notice templates ready to pair with downstream lender decisions.

Our team is made up of engineers who have shipped lending platforms, credit-bureau gateways, KYC stacks and PSD2 / FDX adapters. We work primarily with overseas clients — neobanks, lenders, accounting platforms, identity vendors and dashboard tools — that need lawful, well-documented access to U.S. consumer-finance data.

• Credit-bureau and FICO data integrations across U.S. and EU stacks
• OAuth, mTLS, JWS-signed payloads and certificate-pinning workarounds
• Custom Python, Node.js, Go and Kotlin SDKs plus end-to-end test harnesses
• Full pipeline: protocol analysis → build → validation → compliance memo
• Source-code delivery from $300 — runnable code and full docs; pay after delivery upon satisfaction
• Pay-per-call hosted API — no upfront cost; usage-based pricing

Engagement workflow

1. Scope confirmation — which Kovo data (statements, FICO, alerts, rewards) and which destination systems.
2. Protocol analysis and API design (2–5 business days)
3. Build, internal validation and load testing (3–8 business days)
