Preflight large datasets before network checks begin
Track asynchronous jobs, inspect structured errors, deduplicate inputs, and export results when processing is complete.
How it works
From raw input to trusted verification results without pricing surprises.
Add your data
Step 1 of 4Upload a supported file, paste records, or create a verification job through the API.
Supports .csv, .xlsx, .xls, .txt (up to 1,000,000 rows per job)
Deterministic Normalization
E.164 and RFC parsing happens in local memory before upstream submission. Invalid records are dropped with zero fee.
Encrypted HMAC-SHA256 Cache
Cache keys are computed using HMAC-SHA256 with tenant isolation. Zero plain contact data is stored unencrypted at rest.
Double-Entry Ledger Invariant
All application accounting uses integer USD micros. Maximum quote is frozen before execution, with zero surprise fees.
Asynchronous Webhook Push
Handle high-volume jobs with signed HMAC-SHA256 webhooks, automatic retries, and strict idempotency keys.
Ready to verify your contact data?
Start with free preflight inspection. Review pricing before committing a single credit.
Integrate verification into your product
Create verification jobs, retrieve results and consume supported event notifications through the API. Each service documents its schema, availability, limitations and errors.

Frequently Asked Questions
Preflight normalizes inputs, detects invalid syntax, removes duplicate entries, and checks for eligible cached results before calculating your maximum frozen quote.
Every verification result contains freshness metadata, checked-at timestamps, and cache TTL indicators.
Cached results are used within your tenant isolation scope when within the service TTL. Fresh requests can be forced on demand.
Accounts use integer micros with zero-sum double-entry ledger accounting. Quotes are frozen at preflight, reserved atomically, and reconciled upon job completion.
Yes. Configure webhook endpoints with HMAC-SHA256 signature verification to receive real-time job completion events.
Data is processed strictly to fulfill your requested jobs. Sensitive payloads are encrypted at rest using AES-256-GCM.
