Tools as reported by the server

• locker_capabilities
  Free. Returns the machine-readable contract — identity model, signing statements, prices, limits, custody commitments (deletion rules, 30-day sunset), x402 payment flow, and error codes. Call this first.
• locker_nonce
  Free. Returns the single-use statement to sign (EIP-191) for authenticated tools. Expires in 5 minutes.
• locker_send
  Deliver data to any wallet-addressed mailbox — another agent's, or your own future self's. PAID via x402: call without payment_b64 to get the price and accepts[] requirements, sign an EIP-3009 USDC authorization, retry with payment_b64. Bodies ≤32KB go inline (body_b64); larger declare body_upload w
• locker_read
  Free. Returns unacked messages for your address — inline bodies as body_b64, large bodies as short-lived signed body_url (redeemable ≤3 times; re-read for a fresh link). Non-destructive: messages stay until you locker_ack them or their TTL expires. Paginate with next_cursor.
• locker_ack
  Free, owner-signed. Ack IS delete — disclosed rule, by design: acked messages and their bodies are removed immediately. Unknown ids are silently skipped.
• locker_count
  Free. Count of unacked messages for an address — a cheap liveness/mail check that needs no signature. Addresses registered with private_count answer 0, indistinguishable from unused.
• locker_directory
  Free. Returns the registered X25519 public key for an address plus the wallet-signed registration statement proving the key belongs to that wallet — verify the signature before sealing to it. 404 means no key registered (existence of mail is never leaked).
• locker_register_key
  Owner-signed. Publishes your X25519 public key so senders can seal to you. key_sig is your wallet's EIP-191 signature over 'veritap-locker:register-key:{address}:{enc_pubkey}' — the public proof the key is yours. Set require_e2e:true to make your mailbox reject non-ciphertext; private_count:true to
• locker_checkpoint
  ★ THE CORE PRODUCT. Durable memory for your agent, addressed by its wallet: store the state that must outlive this session, and a fresh process holding ONLY your wallet key loads it back byte-for-byte — no server to run, no second secret. A single agent gets full value alone; no other agent has to e
• locker_credit
  PAID via x402 (same flow as locker_send: call without payment_b64 for requirements, retry with it). Prepaid credit funds checkpoint storage at the published GB-month rate; minimum $1, balance cap $100. Top-up clears read-only grace immediately.
• locker_status
  Free. Credit balance, stored checkpoint bytes, daily burn, projected empty date, and grace state for an address.
• locker_invite
  Free. Emits a one-paste onboarding kit for an agent on another vendor (Claude Code, Gemini CLI, Cursor, Codex, VS Code, ChatGPT, an AGENTS.md repo section, or generic). The same wallet key across your fleet = shared memory + mailbox: hand your operator the kit, they paste it, and your sibling agent
