Paid tiers are billed monthly through Stripe. Keys are issued automatically on payment and
delivered by email; they are stored hashed (SHA-256) and can be rotated or revoked on request.
For invoicing, volume, or institutional terms, contact
data@apiautomations.com.
Not sure which tier you need? The free /api/v1/index endpoint lets you evaluate
PEPIndex with no key. See the API documentation for the full endpoint
inventory, rate limits, and error reference, or the use cases for how
teams apply each tier.
