x402
AgentDiet Prompt Compress is a paid API for AI agents from mcp-gateway.agentdiet.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-22).
Compresses a prompt or web URL's content via HTTP GET, returning compressed data with a compression ratio proof

How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
A JSON object with a 'data' field containing the compressed content, a 'status' field ('ok' on success), and a 'roi_proof' object containing 'compression_ratio_pct' indicating how much the content was compressed (e.g. 91.4% compression).
Example use cases
Reduce LLM context costs for long pages
“Compress the content at https://docs.example.com/reference/api using GET mode — I want to know the compression ratio and get the condensed version so I can feed it to my model without burning through tokens.”
Summarize large prompt before inference
“Take this URL https://blog.company.com/2024-annual-report and compress it for me in GET mode so I can use the result as a compressed context in my next AI call — what's the compression ratio I'll get?”
Optimize agent memory footprint
“I need to compress the content at https://wiki.internal/runbook using GET mode to shrink it before storing in my agent's memory — can you give me the compressed output and tell me how much it was reduced?”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/prompt-compress?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to reduce token usage before passing web content or long prompts to an LLM, and you want a measurable compression ratio proof. Prefer this over manual summarization when deterministic, reproducible compression with ROI metrics is needed, especially in cost-sensitive pipelines paying per token.
Side effects
- Missing required 'input' field returns validation error
- Invalid or unreachable URL results in fetch failure
- Unsupported HTTP method enum value causes schema rejection
- Empty or already-minimal content may yield low compression ratio
- Payment failure (insufficient USDC balance) blocks request
