How this service works
Paid: /v1/verify, /v1/risk, /v1/receipt cost $0.01 USDC per call on Base mainnet via x402 (payTo 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7); utilities analyze Base mainnet (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) by default, network=base-sepolia optional; /v1/receipt/verify and discovery files are free. Operator: Beggar Bot.
Output
Returns the recovered Ethereum address (signer) derived from the provided signature and message/hash/typed_data inputs, along with optional verification status if an expected address was supplied.
Example use cases
Verify wallet ownership claim
“A user says their wallet is 0xABC...123 and provided this signature over the message 'I own this wallet': 0xdeadbeef...cafe — can you recover the signer address and confirm it matches?”
Authenticate EIP-712 typed data signature
“I have a typed data payload and a signature 0xsig...here — can you recover which Ethereum address signed it so I can verify the signer before granting access?”
Audit historical signature provenance
“I have a message hash 0xhash...abc and a signature 0xsig...xyz — recover the Ethereum address that signed this hash so I can cross-check it against our records.”
Technical details
Endpoint
GEThttps://beggar-bot-demand.beggarbot.workers.dev/v1/sigrecover?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to cryptographically recover or verify the Ethereum address behind a signature on Base mainnet, especially within agentic workflows that already use x402 micropayments. Prefer this over general-purpose libraries when you need a hosted, pay-per-call service without managing RPC infrastructure, and when you need support for EIP-712 typed data, raw hashes, and personal_sign in a single API.
Side effects
- Invalid or malformed signature returns an error
- Mismatched hash and message produce an unexpected recovered address
- Missing required 'signature' field returns a 400-level error
- Unsupported encoding value causes a processing error
- Payment not provided or insufficient USDC causes a 402 Payment Required response
- Typed data JSON malformed or unparseable returns an error
