How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://preflight.agentdiet.dev/v1/url-to-markdown)
Output
Returns a distilled data object containing the page content in the requested mode (markdown text, structured JSON tables/metadata, skeleton heading outline, or BM25-focused excerpt), along with ROI proof showing raw vs distilled token counts, compression ratio, estimated LLM cost saved, and optional cache hit/miss status and billing info.
Example use cases
Token-efficient docs lookup for agent
“Pull the Stripe documentation page at https://stripe.com/docs/api and compress it into budget mode with the query 'webhooks' and keep it under 300 tokens so I don't burn my context window.”
Structured data extraction from a product page
“Grab the page at https://example.com/pricing and distill it into structured mode so I can see all the pricing tiers and features as clean JSON tables.”
Skeleton outline of a long article
“Fetch this long article at https://a16z.com/ai-agent-architecture and give me just the skeleton outline so I can quickly understand the section headings and structure without reading the whole thing.”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/url-to-markdown?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read a webpage but must stay within a token budget, reduce LLM inference costs, or get only the relevant portion of a page rather than ingesting the full raw HTML. It is especially valuable when mode=budget with a BM25 query is used to surface only the most relevant content from long pages. Prefer it over raw fetch+parse approaches when compression ratio and cost savings need to be tracked explicitly.
Side effects
- URL is unreachable or returns non-200 HTTP status — endpoint may return an error status
- Raw HTML is malformed or empty — distillation may produce minimal output
- max_tokens too low (below 20) — rejected by schema validation
- mode=budget without a query — BM25 focus may be unfocused or fall back to default behavior
- Payment not provided — x402 payment required response if agent lacks USDC funding
- Rate limits or timeouts on fetching very large pages
