How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://token-intel.agentdiet.dev/v1/prompt-compress)
Output
Returns a JSON object with a 'data' field containing the distilled content (Markdown, structured JSON, skeleton, or BM25 excerpt), plus ROI proof metrics (raw tokens, distilled tokens, tokens saved, compression ratio %, LLM cost saved in USD, ROI multiplier), optional cache status, and billing details.
Example use cases
Compress documentation page for agent
“Fetch https://docs.openai.com/api-reference and distill it into structured JSON tables so I can pass just the key info to my agent without blowing the context window.”
BM25 budget excerpt for research query
“I need you to pull https://en.wikipedia.org/wiki/Transformer_(machine_learning_model) and give me only the parts relevant to 'attention mechanism', staying under 300 tokens using budget mode.”
Convert raw HTML to skeleton outline
“Here's some raw HTML from a product page — can you distill it into a skeleton outline so I can quickly see its structure without reading all 10,000 tokens?”
Technical details
Endpoint
GEThttps://token-intel.agentdiet.dev/v1/prompt-compress?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to consume web page content but the raw HTML or full text would exceed token limits or inflate LLM costs. It is especially valuable when you need BM25-targeted excerpts for retrieval-augmented generation, or when you want clean Markdown or structured JSON output from messy HTML — all at $0.001 per call with built-in ROI reporting.
Side effects
- URL is unreachable or returns non-200 status — fetch fails with error
- HTML payload is malformed or too large to process within token budget
- mode=budget requires both 'query' and 'max_tokens'; missing either may produce unintended output
- Payment not satisfied (HTTP 402) if x402 micropayment not provided
- URL points to paywalled or JavaScript-rendered content that cannot be fetched statically
- max_tokens set too low (below 20) returns validation error
