Lordevo Token Count Estimate
x402
Lordevo Token Count Estimate is a paid API for AI agents from shop.lordevo.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-31).
Estimates the number of LLM tokens in a given text using an offline heuristic, returning a token estimate with low/high range, plus character, word, line, and byte counts.

How this service works
Token count estimate (plus characters, words, bytes): Estimates how many LLM tokens a text uses with a documented offline heuristic (not an exact tokenizer; typically within about 15% for English), with a low/high range, characters, words, lines and UTF-8 bytes. Input: text (POST for long text). Lim
Output
Returns a JSON object with: tokens_estimate (integer), a range object with low and high token estimates, characters (character count), words (word count), lines (line count), bytes_utf8 (UTF-8 byte count), chars_div_4 (characters divided by 4), is_estimate (boolean flag indicating this is an approximation), method (name of the heuristic used), and tool (identifier of the estimation tool).
Example use cases
Prompt length budget check
“Before I send this system prompt to GPT-4, can you estimate how many tokens it uses? Here's the text: 'You are a helpful assistant specialized in customer support for an e-commerce platform. Always respond politely and escalate issues involving refunds to a human agent.'”
Document fits in context window
“I have this article draft and I need to know if it fits within a 4,000-token context window — can you estimate the token count for it? The text is: 'Artificial intelligence is transforming industries at an unprecedented pace. From healthcare to finance, organizations are deploying machine learning models to automate tasks, improve decision-making, and uncover insights hidden in vast datasets.'”
Cost estimation before API call
“I'm about to send a batch of user messages to an LLM API and want to estimate my costs — can you tell me the token count for this sample message: 'Please summarize the following quarterly earnings report in three bullet points, highlighting revenue growth, net income changes, and any forward guidance provided by management.'”

Endpoint
GEThttps://shop.lordevo.com/api/quick/token-count?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, low-cost, offline-heuristic token count without calling an actual LLM tokenizer. It is ideal for pre-flight checks before LLM API calls, cost estimation, context window validation, or any situation where approximate token counts (within ~15% for English) are sufficient. Prefer it over LLM-native tokenizer APIs when latency and cost matter more than exact precision.
Side effects
- Missing 'text' query parameter returns an error
- Text exceeding 400,000 characters may be rejected or truncated
- Very short or empty text may return near-zero estimates
- Non-UTF-8 encoded input may cause byte count inaccuracies
- Heuristic can be off by up to ~15% for non-English or code-heavy text
- Network timeout if the service is unavailable
