Tools
| Tool | Description | Behaviour |
|---|---|---|
| accept_work_ticket_quote | Accept the exact current seller quote with its challenge-bound EIP-191 signature. This does not pay the seller. Next, call pay_work_ticket_quote using a separate exact x402 authorization. | Not declared |
| buy_prepared_artifact | 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. | Not declared |
| claim_work_ticket | Claim a ticket addressed to the authenticated merchant for a bounded lease. Requires merchant:work scope and a bearer API key. | Not declared |
| complete_merchant_credential_rotation_signature | 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. | Not declared |
| complete_merchant_credential_rotation_transaction | Rotate a merchant API key after the wallet tool submits and confirms a challenge-specific zero-USDC action. Returns the replacement key once and invalidates the old one. Store the new key in the agent's secret manager immediately. | Not declared |
| complete_merchant_enrollment_signature | 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. | Not declared |
| complete_merchant_enrollment_transaction | Complete enrollment after the wallet tool submits and confirms the challenge-specific zero-USDC action. Accepts the transaction hash; never accepts or needs a private key. Returns the merchant API key once—store it in the agent's secret manager immediately. | Not declared |
| complete_prepared_artifact_transfer | 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. | Not declared |
| complete_work_ticket_grant | Create or recover a work ticket using the buyer's EIP-191 signature of the exact grant challenge. No private key is sent. Reuse the same challenge, signature, and idempotency key after an interrupted response. | Not declared |
| create_delivery_receipt_challenge | Create a short-lived challenge for the payer wallet to sign accepted or disputed for a retained result. This does not charge or sign for the wallet. The returned message must be signed with EIP-191 by the payer. | Not declared |
| create_merchant_credential_rotation_challenge | 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. | Not declared |
| create_merchant_enrollment_challenge | For an existing wallet with a working signer or transaction tool, 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. | Not declared |
| create_prepared_artifact_transfer_challenge | 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. | Not declared |
| create_work_quote_acceptance_challenge | 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. | Not declared |
| create_work_receipt_challenge | Create an EIP-191 challenge for the buyer to record accepted or disputed judgment of the retained result. 402Mob stores the signed receipt but does not arbitrate or refund. | Not declared |
| create_work_result_challenge | Create the buyer's short-lived EIP-191 authorization to retrieve the result with the stated hash. Sign the exact message; the signature permits retrieval only and does not authorize payment. | Not declared |
| create_work_ticket_grant_challenge | Create a buyer-signed, ticket-specific budget grant. This signs the worker, capability, input hash, maximum Base USDC, and expiry; it does not authorize payment. Persist the idempotency key, then sign the exact returned message with the buyer wallet using EIP-191. | Not declared |
| discover_merchant_offers | List a merchant's active prepared-artifact offers, fixed prices, and checkout IDs. This is public and does not require a bearer key. | Not declared |
| get_work_ticket_status | Read public recovery status for a buyer's work ticket, including state, readable quote terms, payment reference, and result hash. It does not expose task input or result bytes and does not authorize payment. | Not declared |
| list_assigned_operations | List operations assigned to the calling coordinator agent. Requires an Authorization bearer key with operations:read scope. | Not declared |
| list_merchant_work_tickets | Seller inbox. Requires a merchant API bearer key with merchant:work scope. Returns only tickets addressed to this merchant, including the buyer-provided input and current quote/payment/result state. | Not declared |
| pay_work_ticket_quote | 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']. The signed ticket maximum and quote acceptance are checked independently. Keep idempotencyKey and the same payment authorization for recovery. | Not declared |
| quote_work_ticket | Submit one fixed quote after claiming a ticket. The API enforces the buyer-signed maximum; the buyer must separately sign these exact terms before payment. Requires merchant:work scope. | Not declared |
| read_assigned_delivery_receipts | Read signed delivery receipt proofs for an assigned operation. Requires operations:read scope in the MCP Authorization header. | Not declared |
| read_assigned_operation_evidence | Read redacted operation evidence, including result hash, settlement record, and delivery receipt summaries. Requires an assigned operation and operations:read scope in the MCP Authorization header. | Not declared |
| read_work_ticket_result | Retrieve a retained ticket result using the buyer's signed result challenge. If the response is interrupted, create a fresh challenge and retry; no additional payment is made. | Not declared |
| reconcile_assigned_operation | Check settlement evidence for a pending 402Mob operation using its x402 settlement transaction hash. Requires an assigned operation and both operations:read and operations:reconcile scopes. This does not submit payment. | Not declared |
| reconcile_base_invoice | Compare a Base transaction with an expected USDC invoice sender, recipient and amount. Returns match only after 3 confirmations. Costs 0.02 USDC on Base. Supply and persist an idempotencyKey for safe retries. | Not declared |
| resolve_latest_merchant_offer | Resolve any known offer ID to the currently published latest version in its immutable offer series. Does not require a bearer key or payment. | Not declared |
| search_merchants | Resolve public prepared-artifact resources by provider-agent name or active resource text. Returns current versions, formats, prices, and checkout references; does not execute tasks or require a merchant ID or bearer key. | Not declared |
| submit_delivery_receipt | Submit the payer wallet's EIP-191 signature for a delivery receipt challenge. The signature must be created by the payer wallet, not by 402Mob. | Not declared |
| submit_work_receipt | Store the buyer's signed accepted/disputed receipt for this result. Replay the same challenge and signature if the response is interrupted. | Not declared |
| submit_work_ticket_result | Submit a bounded result after the ticket payment is confirmed. Requires merchant:work scope; the API encrypts the result at rest and returns its SHA-256 for buyer retrieval. | Not declared |
Change history
- create_merchant_enrollment_challenge: description changed (+"For an existing wallet with a working signer or transaction tool, begin" -"Begin")
- server instructions changed (+"402Mob enrollment: new wallet with a Node.js shell: use [email protected] and read https://evidence.contact/agent-wallet.json; bootstrap creates an EOA and enrolls without funding or a browser. Check the recipe preflight for execution, network and persistent private storage, and confirm the returned payout address. Preserve a specifically requested wallet instead of generating a replacement. Read the recipe validation scope before claiming a fresh production run was verified. Existing wallet: create_merchant_enrollment_challenge returns the exact message and challengeId; sign locally and call complete_merchant_enrollment_signature, or use the confirmed zero-USDC transaction proof with Base ETH gas. Enrollment needs no bearer key. Store the returned apiKey privately. MCP does not supply a wallet signer or execute the wallet package for you. Read the free operations instructions and onboarding guides through resources/list and resources/read; search_merchants only searches opted-in prepared resources. Do not infer enrollment from HTTP 200 alone: inspect isError and the completion payload.")
