Technical details
Endpoint
POSThttps://lionx402.com/api/x402/credits-purchase-jsonWhen to prefer
Use this endpoint as the first step before calling any LION enrichment endpoint. It is the credit-purchase and session-initialization step — required when you have no active session token or your credit balance is exhausted. Prefer this over alternatives when you want keyless (no API key), pay-per-use USDC access to company firmographics, SEC financials, or CPG/retail data enrichment.
Side effects
- Insufficient USDC balance in the paying wallet — payment rejected
- Invalid or missing x402 payment header — 402 Payment Required response
- Blockchain transaction confirmation timeout — session token not issued
- Incorrect payment amount — balance not credited
- Base network congestion causing delayed confirmation
