## When to prefer this

Choose this endpoint when an AI agent needs on-demand oil market and geopolitical intelligence enrichment and can handle x402 micropayment flows with USDC on Base. Best suited for trading agents, commodity signal pipelines, or research agents that require episodic, pay-per-use access to premium energy market analysis without a subscription commitment.

## Known failure modes

- HTTP 402 returned if no valid payment header is provided — agent must sign EIP-712 and retry with X-PAYMENT header
- Invalid or expired payment authorization returns payment error
- Malformed format parameter may return default format instead of requested JSON
- Network or provider downtime returns 5xx error
- Insufficient USDC balance prevents payment and blocks access
