How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://whale-momentum.agentdiet.dev/v1/context-trimmer)
Output
Returns a distilled data object (Markdown, structured JSON tables/metadata, skeleton outline, or BM25 budget excerpt depending on mode), along with ROI proof metrics (raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD), cache status, and billing details.
Example use cases
Compress docs for agent context
“Fetch the OpenAI API docs page at https://platform.openai.com/docs/overview and distill it into compact markdown so I can fit it into my agent's context window without burning too many tokens.”
BM25 budget excerpt for research
“I need just the parts of https://en.wikipedia.org/wiki/Retrieval-augmented_generation relevant to 'vector databases' — use budget mode with a max of 300 tokens so my LLM doesn't get overwhelmed.”
Structured tables from a product page
“Pull https://aws.amazon.com/ec2/pricing/ and distill it in structured mode so I get the pricing data back as JSON tables rather than raw HTML.”

Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/context-trimmer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to inject live web content into an LLM prompt but must stay within token limits or minimize LLM inference costs. It is especially useful for agent pipelines that repeatedly access the same documentation pages, structured product data, or research pages. Prefer it over raw fetch-and-parse when you need BM25-focused excerpts, token budget enforcement, or structured JSON extraction from HTML without writing your own parsing logic.
Side effects
- Invalid or unreachable URL returns an error status
- max_tokens set below minimum of 20 causes validation failure
- query parameter required when mode=budget but not provided
- Raw HTML too large to process within service limits
- Payment failure via x402 prevents endpoint access
- Cache miss on uncached URLs increases latency
