Technical details
Endpoint
GEThttps://x402.wintergreen.uk/api/v1/knowledge/oral-board-prepWhen to prefer
Choose this endpoint when an AI agent needs structured, on-demand career guidance specifically for firefighter oral board interview preparation and the user is willing to pay a $2.50 USDC micropayment per retrieval. Prefer over free web searches when a curated, expert-authored guide is needed rather than scattered forum advice. Suitable for agents that already support the x402 payment protocol on Base.
Side effects
- HTTP 402 returned if payment header is missing or malformed — agent must sign EIP-712 TransferWithAuthorization and retry with X-PAYMENT header
- Invalid or expired payment signature causes rejection
- Incorrect USDC amount (must be exactly 2.5 USDC) causes payment failure
- Wrong chain (must be Base eip155:8453) causes payment failure
- Empty or missing _slug parameter may return wrong or no content
- Network timeout if Base chain is congested during payment verification
