How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns a structured validation result indicating whether the submitted Ethereum address is valid, whether the checksum is correct (EIP-55), and any format issues detected. Each response also includes a cryptographic audit record with chain hashing for provenance and compliance tracking.
Example use cases
Pre-transfer wallet address check
“Before I initiate this ETH transfer, can you verify that 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B is a properly formatted and valid Ethereum address?”
User onboarding wallet validation
“A new user just entered their Ethereum wallet address as 0x1234567890abcdef1234567890abcdef12345678 — can you validate it's a real, correctly checksummed ETH address before we save it to their profile?”
Smart contract interaction safety check
“I'm about to call a smart contract with recipient address 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe — can you confirm this is a valid Ethereum address with correct checksum so I don't lose funds?”
Technical details
Endpoint
POSThttps://api.strale.io/x402/v2/eth-address-validateWhen to prefer
Choose this endpoint when you need a fast, auditable Ethereum address validation with cryptographic proof of the check — especially useful in compliance-sensitive workflows, payment pipelines, or agent systems that need tamper-evident logs. Prefer it over a simple client-side regex when you need EIP-55 checksum verification, audit trails, or a trust layer that downstream systems can verify.
Side effects
- Invalid or missing address field returns a validation failure with error detail
- Malformed input (non-hex characters, wrong length) flagged as invalid format
- Network or service errors return standard HTTP error codes
- Expired or insufficient x402 payment token results in 402 Payment Required response
