How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://json-repair.agentdiet.dev/v1/prompt-compress)
Output
Returns a JSON object containing distilled content in the requested format (Markdown, structured JSON tables/metadata, skeleton outline, or BM25 budget excerpt), along with ROI proof metrics showing raw token count, tokens saved, compression ratio percentage, distilled token count, and estimated LLM cost saved in USD. Also includes cache status (HIT/MISS) and billing information.
Example use cases
Inject docs page into agent context
“Fetch and compress the Stripe docs page at https://stripe.com/docs/api into structured mode so I can inject the key tables and metadata into my agent's context without blowing the token limit.”
BM25 budget excerpt for research query
“Pull the content from https://en.wikipedia.org/wiki/Large_language_model and give me a BM25-focused excerpt about 'context window scaling' with a max of 400 tokens — I need it tight for a downstream prompt.”
Distill raw HTML from scraped page
“I've got raw HTML from a competitor pricing page — distill it into a skeleton outline so I can see just the structure and headings without all the noise.”

Endpoint
GEThttps://json-repair.agentdiet.dev/v1/prompt-compress?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to reduce a webpage or HTML blob to a minimal token footprint before injecting into an LLM prompt — especially when you have a strict token budget (use mode=budget with a BM25 query and max_tokens), want structured table/metadata extraction, or need skeleton outlines for navigation. Prefer this over generic scrapers when token cost savings and ROI proof metrics matter to your workflow.
Side effects
- Missing required 'url' parameter returns validation error
- Unreachable or blocked URL results in fetch failure
- mode=budget without 'query' parameter may yield unfocused results
- max_tokens below minimum of 20 is rejected
- Invalid URL format causes parse error
- Payment not included or rejected returns HTTP 402
- HTML too large may exceed processing limits
