## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability lion-credits-purchase-x402-7c3fc31a -d '<json body>'
```

Example prompt: I want to start using the LION enrichment API — can you purchase 0.1 USDC worth of credits on Base so I get a session token I can use to look up company firmographics?

## When to prefer this

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.

## Known failure modes

- 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

## How this service works

Keyless x402 on Base USDC for AI agents: cheapest OFAC wallet screen ($0.001), multi-list sanctions + signed compliance receipt, company research/org enrich from $0.03, verified company file $0.95. Live Wikidata+SEC+DNS+GLEIF. Ed25519-attested. No API key. People enrichment elsewhere; companies + counterparty proof on LION. npx agentcash add https://lionx402.com

## Output

Returns a JSON object with an asset_id (e.g. CREDITS_PURCHASE_001), a balance in micro-units (e.g. 100000 = $0.10 USDC), and a session_token (prefixed lct_...) that can be passed to subsequent LION enrichment endpoint calls to authorize pay-per-field queries.
