How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the top 10 character tokens ranked by frequency or some computed statistic derived from the input text, including character identities and their associated counts or scores.
Example use cases
NLP preprocessing character analysis
“I need to know the top 10 most frequent characters in this article excerpt before I run it through my tokenizer — here's the text: 'Natural language processing enables computers to understand human language in a meaningful way, allowing machines to read, decipher, and make sense of human languages.'”
Detecting language script composition
“Can you analyze the character distribution of this user-submitted text and show me the top 10 characters by frequency? The text is: 'Bonjour! Comment allez-vous? Je suis très heureux de vous rencontrer aujourd'hui dans cette belle ville.'”
Content fingerprinting for duplicate detection
“Run a top-10 character frequency analysis on this product description so I can use it as a lightweight fingerprint: 'Introducing the UltraBlend Pro 3000 — the most powerful countertop blender with 10 speed settings, a 72-oz BPA-free pitcher, and a self-cleaning mode.'”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-token/characters/t10?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call character-level frequency or token analysis of a text without setting up a heavy NLP pipeline. It is ideal for agents doing quick text fingerprinting, preprocessing checks, or character distribution audits on documents up to 50,000 characters. At $0.03 USDC per call it is cost-effective for single-document spot checks.
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- Empty text field causes computation error or empty result
- Payment failure via x402 if USDC balance is insufficient
- Malformed JSON body returns 400 error
- Ambiguous or binary/non-UTF8 text may produce unexpected character stats
