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 JSON object with a 'result' field containing the SHA-256 hex digest of the input string, plus a 'meta' object with call metadata. The hash is deterministic and model-free.

Example use cases

Example prompt

“Can you compute the SHA-256 hash of the string 'Hello, world! This is my transaction payload.' using exact deterministic arithmetic — I need the hex digest to verify data integrity.”

When to prefer

Choose this endpoint when you need a guaranteed deterministic SHA-256 hash computed server-side rather than relying on an LLM's potentially hallucinated or approximate output. Useful for data integrity checks, transaction payload fingerprinting, or verifying stored digests where exact correctness is critical.

Side effects

Missing or empty 'input' field returns a validation error
Payment of 0.001 USDC not provided returns a 402 Payment Required response
Invalid JSON body causes a parse error
Extremely large input strings may exceed worker payload limits
Network timeout from Cloudflare Workers cold start

Input

  "input": "Hello, world! This is my transaction payload."
