How this service works
Deterministic finance and crypto math for AI agents: TradFi (NPV, IRR, XIRR, Black-Scholes + Greeks, bonds, VaR, Sharpe) and DeFi (impermanent loss, perp liquidation, funding, Uniswap v3, health factor, cost basis). Exact, model-free arithmetic that LLMs get wrong — priced per call in USDC.
Output
Returns a result object with computed text statistics (such as word count, character count, or other string metrics) plus a meta object with call metadata.
Example use cases
Example prompt
“Can you run text stats on this passage: 'The quick brown fox jumps over the lazy dog. Pack my box with five dozen liquor jugs.' — I want to know things like word count and character count.”
Technical details
Endpoint
POSThttps://finmath.qzqh5rrbkz.workers.dev/v1/text_stats?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need deterministic, exact text statistics computed server-side rather than relying on an LLM's approximate counting. Useful when you need reliable word or character counts for billing, truncation, or validation purposes and want a paid-per-call microservice with x402 USDC payment.
Side effects
- Missing required 'text' field returns validation error
- Empty string may return zero-value stats or an error
- Payment not included or insufficient USDC returns 402 Payment Required
- Extremely long text strings may be rejected or time out
- Malformed JSON body returns 400 error
