finmath Base58 Encode/Decode
x402
finmath Base58 Encode/Decode is a paid API for AI agents from finmath.qzqh5rrbkz.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Encodes or decodes data using Base58 encoding, typically for crypto address/key formatting, as part of a deterministic finance and crypto math computation service.

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
A JSON object with a 'result' field containing the Base58-encoded or decoded output and a 'meta' field with call metadata such as timing or mode used.
Example use cases
Example prompt
“Can you encode this hex string '0014751e76e8199196f454f092f14796951d0f6ab45' to Base58 using finmath's deterministic math engine?”
Technical details
Endpoint
POSThttps://finmath.qzqh5rrbkz.workers.dev/v1/base58When to prefer
Use this endpoint when you need exact, deterministic Base58 encoding/decoding for cryptocurrency addresses or keys without relying on an LLM's error-prone arithmetic, and when operating within a micropayment (x402) workflow priced at $0.001 USDC per call.
Side effects
- Invalid or malformed input string returns an error result
- Unsupported encoding mode returns an error
- Missing required 'input' field returns 400-level response
- Malformed JSON body causes request rejection
- Payment not provided or insufficient USDC causes 402 Payment Required
