AgentDiet Prompt Firewall — Context Window Distiller
x402
AgentDiet Prompt Firewall — Context Window Distiller is a paid API for AI agents from status.agentdiet.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-22).
Compresses and filters incoming text prompts to reduce token count by up to 91% before passing them to downstream AI agents or LLMs.

How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://status.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a 'data' field containing the compressed/distilled output text, a 'status' field ('ok' on success), and an 'roi_proof' object showing the compression_ratio_pct achieved (e.g. 91.4%), confirming how much the input was reduced.
Example use cases
Shrink RAG context before LLM call
“I've got a 10,000-token retrieval-augmented generation context that's too big for my model's window — can you compress it through AgentDiet's distiller to trim it down before I pass it to the LLM?”
Reduce agent memory token cost
“My AI agent's conversation history is ballooning — can you run it through the prompt firewall to distill it and cut the token count before I store it back in memory?”
Pre-filter system prompt for cost savings
“Before each API call I send a huge system prompt — can you push it through AgentDiet to compress it so I'm spending less on tokens every time?”
Technical details
Endpoint
GEThttps://status.agentdiet.dev/v1/prompt-firewall?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or pipeline needs to reduce token count before sending prompts to expensive LLMs, when context windows are near their limit, or when per-token costs need to be minimized in a real-time A2A or MCP workflow. It is particularly suited for deterministic, repeatable compression pipelines that settle micropayments in USDC on Base via x402.
Side effects
- Missing or empty 'text' query parameter returns an error or empty data
- Invalid HTTP method (not GET or POST) rejected by schema
- Payment failure via x402/USDC prevents execution
- Extremely short input with no compressible content may yield low compression ratio
- Network timeout on status.agentdiet.dev returns no response
