Data and verification providers
When the unit of sale is the call
Identity checks, credit lookups, document verification. The product is the request, which means a disputed invoice is a disputed count and nothing else.
- Idempotent metering
- Re-runnable rating
- Spend visible per consumer
What is usually in the way
Retries counted as sales
A client's network blips, their code retries, and your invoice charges twice for one answer. The dispute that follows costs more than the call did.
Counts nobody can reproduce
The number on the invoice comes from a log pipeline. The number the client has comes from theirs. Neither can be recomputed.
No way to sell a trial
Without a genuine test environment, evaluating your product means being billed for it, which slows every deal down.
What Wanda does about it
These are the properties that decide whether a per-call product can be billed without argument.
Spend as it accrues
A consumer transaction log and a provisional spend figure, so a client watches the bill form rather than meeting it at month end.
Self-service onboarding
Invitation onto an existing account, plus self-serve into a test-only account with live keys gated on your approval.
Published guides
Written guides beside the API reference, so a first call does not need a conversation.
A retry is not a sale
Identity is the event id and timestamp your own system assigns, once, and immutable across retries. A byte-identical resend is answered as a duplicate rather than counted.
Counts you can defend
Rating re-runs over the same aggregates and produces the same figure, so a query becomes a recomputation rather than an argument.
Test mode that is really free
Sandbox credentials in their own environment, whose usage never reaches a statement, so a prospect can evaluate at full fidelity.
Per-resource pricing
Price each product separately: an identity check and a document check are different lines on the same statement, at their own rates.
Headroom before the wall
Rate limit and quota state ride on every response while a call is still succeeding, so a client sees the ceiling coming.
No personal data in the meter
The usage path refuses an attribute that looks like a personal identifier, by key name and by value. Your compliance posture is not weakened by billing.
