## When to prefer this

Choose this endpoint when you need a fast, deterministic, offline Base58 decode operation with no LLM or network involvement. Prefer the free sandbox endpoint POST /v1/sandbox/base58-decode first if available; use this paid endpoint ($0.002 USDC) when the sandbox is unavailable or for production workloads. Ideal for blockchain addresses, IPFS CIDs, or any identifier known to be Base58-encoded.

## Known failure modes

- Invalid Base58 characters in input (e.g. contains '0', 'O', 'I', or 'l') return a decoding error
- Empty or null input string returns a validation error
- Input exceeding 100,000 characters is rejected
- Malformed or non-Base58 encoded strings may return a parsing error or garbled output

## How this service works

Call when an agent needs text decoded with base58. No network and no LLM. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/base58-decode first.

## Output

The decoded output corresponding to the input Base58-encoded string, returned as the original data (bytes or string) that was encoded.
