x402
Delx Base58 Validate is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Validates whether a string consists entirely of characters from the Bitcoin Base58 alphabet, locally and deterministically, with no live chain access.

How this service works
Validate Bitcoin-base58 alphabet membership for local address hygiene — call when checking Bitcoin-base58 alphabet membership locally. Use for chain input hygiene without live RPC—adjacent to OneSource-class small chain reads, but static/local only so rights and margin stay clear. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip,…
Output
Returns a deterministic machine-readable JSON object indicating whether the submitted string consists exclusively of characters from the Bitcoin Base58 alphabet (no live chain state, no network calls). Includes a boolean membership result and is stateless and memory-free.
Example use cases
Address hygiene before payment flow
“Before I send this transaction, check if '3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy' is made up of valid Bitcoin Base58 characters only — I just need a local format check, not a live chain lookup.”
Batch input sanitization for user submissions
“A user just submitted '0OIlBitc0inAddr3ss' as a Bitcoin address — can you validate whether it's valid Bitcoin Base58 alphabet? I want to reject it early if it has illegal characters before passing it to my backend.”
Debugging address parsing pipeline
“I'm getting errors in my address parser and I think the input has non-Base58 characters — can you run a local Base58 alphabet check on 'bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq' to see if it passes?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/base58-validateWhen to prefer
Use this endpoint when you need a fast, cheap, stateless local check that a string only contains Bitcoin Base58 alphabet characters (alphanumeric excluding 0, O, I, and l) — without any live RPC, blockchain node, or network call. Prefer it over full address validation APIs when you only need character-set hygiene as an early filter, or when you want to avoid the latency and cost of on-chain lookups for bulk input sanitization.
Side effects
- Empty or missing 'value' field returns an error or false result
- Strings containing Base58Check prefix or checksum bytes may pass alphabet check but semantic validity is not guaranteed
- Non-string input types may cause schema validation errors
- No network errors possible since the check is purely local
