How this service works
Offline deterministic checks (no ML, no scraping) for business identifiers and rental due-diligence, paid per call via x402 (gasless EIP-3009 USDC on Base). Checksum-verifiable (IBAN, LEI, VAT, ABA, ISBN, SEDOL…) vs format-only (EIN, IFSC, SWIFT/BIC…) — every response returns a scope field. Non-custodial, signed receipts. First 3 calls/day free.
Output
A JSON object containing: valid (boolean), word_count (total words), meaningful_word_count (non-filler words), top_words (array of frequent/significant terms), content_hash (deterministic hex hash of the input), first_sentence (extracted opening sentence), tool (endpoint identifier), and scope (describing what validation or analysis was applied).
Example use cases
Fingerprint document for deduplication
“I need a deterministic content hash plus word count for this lease agreement paragraph so I can detect duplicates across my document store: 'All parties agree to the terms and conditions set forth herein. Any amendments must be made in writing and signed by all parties.'”
Extract top keywords from business description
“Pull out the top words and first sentence from this company description so I can index it: 'Acme Corp specializes in industrial-grade robotics for warehouse automation. Founded in 2010, we serve clients across North America and Europe.'”
Measure meaningful content density of scraped text
“Check the word count versus meaningful word count on this scraped paragraph to see how much filler it has: 'So basically, um, the thing is, the product is actually really quite good and, you know, customers like it a lot.'”
Technical details
Endpoint
POSThttps://hcrb.in/v1/tools/context-distill/call?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, offline, deterministic text distillation with no ML inference or external scraping — particularly when reproducibility and content hashing matter (e.g. deduplication, audit trails). It is ideal for agents that need to fingerprint, summarize statistics, or extract top words from text in a privacy-preserving way. The micropayment model ($0.005/call via x402 USDC) makes it cost-effective for high-volume processing at scale. Prefer it over ML-based summarizers when you need deterministic, verifiable outputs rather than generative paraphrases.
Side effects
- Invalid or empty input text returns valid:false with zeroed metrics
- Payment not included or insufficient USDC triggers HTTP 402 before processing
- Malformed POST body returns error before distillation occurs
- Rate limit exceeded beyond 3 free calls/day without payment causes rejection
