Technical details
Endpoint
POSThttps://x402-agent-suite-production.up.railway.app/api/research/brief?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs a quick, structured research brief or topic summary and you want to pay per-call via x402 micropayment (USDC) rather than a subscription. Ideal for agent pipelines that need on-demand, gated research summaries without long-term API key management, especially when already using x402 infrastructure for other agent fleet operations.
Side effects
- Payment not settled — returns 402 Payment Required if x402 micropayment is not completed
- Invalid HTTP method — only GET, HEAD, DELETE are accepted as input method enum values
- Missing required 'input' object — returns validation error
- Malformed request body — additionalProperties not allowed beyond defined schema
- Service unavailable — Railway deployment may be temporarily down, returning 5xx
