create_merchant_enrollment_challenge
Advertised by the server during the last successful anonymous check.

Begin headless merchant enrollment. Returns the exact five-minute EIP-191 message and a Base USDC approve-zero or transfer-zero alternative. Sign the exact message with the merchant wallet, then call complete_merchant_enrollment_signature; or use the wallet action and complete_merchant_enrollment_transaction. 402Mob never receives a private key. Store the returned merchant API key securely.

complete_merchant_enrollment_signature
Advertised by the server during the last successful anonymous check.

Complete merchant enrollment using the EIP-191 signature of the exact message returned by create_merchant_enrollment_challenge. Accepts only a wallet signature, never a private key. Returns the merchant API key once; store it in the agent's secret manager immediately and do not log the result.

create_merchant_credential_rotation_challenge
Advertised by the server during the last successful anonymous check.

Begin recovery of a lost merchant API key. Returns a five-minute wallet-bound challenge for either gas-free EIP-191 signing or a zero-USDC Base transaction proof. The wallet signs or submits the action; 402Mob never signs for it.

complete_merchant_credential_rotation_signature
Advertised by the server during the last successful anonymous check.

Rotate a lost merchant API key by submitting the merchant wallet's EIP-191 signature of the exact message returned by create_merchant_credential_rotation_challenge. This method needs no transaction or gas. It returns the replacement key once and invalidates the old one; store the new key securely.

Advertised by the server during the last successful anonymous check.

Prepare a noncustodial direct-USDC checkout for a prepared artifact. Returns the seller's payout address and exact amount, plus a separate challenge-bound zero-USDC approval that proves the buyer wallet controls the purchase. Both wallet actions are submitted by the buyer's own wallet tool; 402Mob never holds funds or signs transactions.

complete_prepared_artifact_transfer
Advertised by the server during the last successful anonymous check.

Verify a direct Base USDC artifact payment and the buyer's separate zero-USDC wallet-control proof, then deliver the retained artifact. On timeout, retry the same challenge, transaction hashes, and idempotency key; do not send USDC again. The transaction hash alone is not enough to claim a purchase.

buy_prepared_artifact
Advertised by the server during the last successful anonymous check.

Buy an active prepared artifact from a wallet-enrolled merchant with standard x402: the first call returns payment requirements; sign locally and retry the same arguments with _meta['x402/payment']. For a wallet tool without typed-data signing, use create_prepared_artifact_transfer_challenge, send the exact USDC amount, make the separate zero-USDC wallet proof, then call complete_prepared_artifact_transfer. Reuse the same identifiers and payment proof after timeouts.

Advertised by the server during the last successful anonymous check.

Ask 402Mob for the exact EIP-191 message binding buyer, seller wallet, quote ID, quote hash, expiry, and exact Base USDC amount. This is quote acceptance only; the payment requires a separate x402 authorization.

Pay the buyer-accepted quote directly to the seller with x402 Base USDC. First call returns exact requirements; sign them with the buyer wallet and retry with _meta['x402/payment'].
