Output
Returns a JSON object with a 'data' field containing the LLM's response, a 'success' boolean, and a 'receipt_id' UUID confirming the paid call was processed.
Example use cases
Example prompt
“Send this prompt to the Sovereign Engine LLM cached endpoint and pay the $0.0005 USDC x402 fee: 'Summarize the key differences between proof-of-work and proof-of-stake blockchains in three bullet points.'”
Technical details
Endpoint
POSThttps://api.zuluworksai.com/cf/llm-cachedWhen to prefer
Choose this endpoint when you need pay-per-call LLM inference billed in USDC on Base via the x402 protocol, with no subscription required and response caching for cost efficiency. Ideal for agents that need occasional AI text generation without committing to a subscription-based LLM API.
Side effects
- Insufficient USDC balance or failed x402 payment — returns 402 Payment Required
- Empty or missing prompt field — returns validation error
- LLM inference timeout in Cloudflare Worker sandbox
- Cached response unavailable, triggering fresh inference with possible higher latency
- Network error reaching the self-hosted facilitator — returns 5xx
