ClawPurse Micropayment Ecosystem
A local NTMPI wallet and HTTP 402 payment gateway for DePIN operators, validator treasuries, and agentic AI. Send, stake, gate APIs, and verify transactions on-chain — with encrypted guardrails and zero third-party custody.

ClawPurse Wallet
Local-only NTMPI wallet with AES-256 encrypted keystores, destination allowlists, staking automation, and a guardrail wizard. CLI and programmatic API for agents, scripts, and human operators.

HTTP reverse proxy implementing 402 Payment Required. Gate any API behind NTMPI micropayments with pay-per-request invoicing, prepaid balances, on-chain verification, and route-level pricing.
View Gateway Site →Wallet + Gateway = micropayment stack
An AI agent hits a gated API, receives a 402 invoice, pays on-chain with ClawPurse, and retries with proof. The gateway verifies the transaction on Neutaro and proxies the request upstream. No accounts, no API keys — just on-chain settlement.

ClawPurse Wallet features
Everything you need to manage NTMPI locally — with guardrails built for autonomous agents.
Encrypted Keystore
AES-256-GCM with scrypt key derivation. Mnemonics stay locked to the local node.
Guardrail Wizard
Interactive setup for send limits, confirmation thresholds, and allowlist enforcement mode.
Destination Allowlists
Enforce or document trusted addresses with per-destination caps, required memos, and notes.
Transaction Receipts
Every send recorded locally with tx hash, block height, memo, and guardrail status for full audit trails.
Staking & Delegations
Delegate, undelegate, redelegate NTMPI. Discover validators, track rewards, and manage the 22-day unbonding period.
Programmatic API
Import wallet functions directly into agents and scripts. send(), getBalance(), delegate() and more.
Monetize any API with NTMPI micropayments
The ClawPurse 402 Gateway sits in front of your upstream API and handles invoicing, on-chain verification, and proxying. Two payment flows, route-level pricing, and a JWT-protected management API.
Pay-per-request
Client receives a 402 invoice, pays on-chain, retries with X-Payment-Proof header. Gateway verifies and proxies.
Prepaid balance
Client deposits NTMPI once. Subsequent requests use X-Client-Id and the gateway deducts per call — no repeated on-chain transactions.
On-chain verification
Queries Neutaro REST API to confirm payment amount, memo, and block confirmations.
Route-level pricing
Default price per request plus per-route overrides. Cheap reads, expensive writes.
Docker & bare-metal deploy
One-command docker compose up or Ubuntu deploy script. SQLite storage, zero external dependencies.

First-class support for agentic AI
ClawPurse was built inside the OpenClaw ecosystem. Autonomous agents get wallet access with human-grade guardrails. Proof-of-work faucets, bounty payouts, 402 API calls, or automated restakes — all from the same local keystore.
SKILL.md — Agent Integration Guide
Complete documentation for OpenClaw agents, automation scripts, and AI assistants. Covers the wallet API, 402 gateway flow, security best practices, and integration patterns.

The OpenClaw skill wraps the CLI for drop-in agent usage. Pipe receipts straight back to chat.
Priority faucet lanes
Timpi Drip gives OpenClaw-authenticated agents a higher throughput drip for faster onboarding.
PoW over CAPTCHA
Agent-friendly proof-of-work replaces CAPTCHA. ClawPurse ships the PoW solver that powers Timpi Drip.
Autonomous 402 flow
Agents detect 402 responses, parse invoices, pay on-chain, and retry with proof — all programmatically.

Powered by Timpi & the Neutaro blockchain
ClawPurse is the payment layer for Timpi's independent search network. Timpi combines privacy-first search, an open Data API, and DePIN nodes that reward operators for running the TAP network.
Search, Data, DePIN
- Search Engine: censorship-resistant results with no profiling or tracking.
- Data API: programmatic access to the decentralized index.
- DePIN nodes: Collectors, Guardians, and GeoCores that earn NTMPI.
