GenTech Labs x402 - Security

Send one SMS to a mobile number, paid per message in USDC with x402. Use it when an agent must notify a person by text. The 402 quotes the exact price for the destination and message length. No account and no API key: any wallet that pays sends in one call. An opt-out link is appended to the message, and numbers that opted out are refused. Returns an order; poll GET /v1/orders/{id} for delivery status.

Timestamps, UUIDs, gas, domain intel, memory, and text extraction.

x402Pulse Pro: a 30-day pass for $39 USDC that returns an API key for unlimited calls (fair use: 120 a minute, 20,000 a day) to every x402Pulse endpoint, plus an MCP server for Claude Code, Cursor and Claude Desktop. Pass ?renew=<key> to extend a key. The key is shown once.

Kuchari Agentic Data Platform: describe your data, get a quote, pay via x402, get a Docker image with a pipeline over HTTP file archives, Confluence Cloud, Google Drive, Open-Meteo weather and 42 more; answers over MCP with citations: facts like meeting decisions and action items, threshold flags, knowledge graph with contradictions, BASIC listings from scans, passage search, OCR. Pay only for a tested build; runs without us. Start: https://34-179-245-189.sslip.io/.well-known/agent-card.json

A minimal x402 canary endpoint for machines to verify that they can discover, pay, and receive a valid response.

Diagnose x402 protocol and discovery configuration with separate linter and compliance grades. Optional quote_mode fast returns a payable first 402; resend the same input with proof, save the job/capability and poll. Default preserves compute-first admission. Base or Solana, 0.05 USDC per completed scan. Failed or expired unfinished work is uncharged; never replace a pending proof. Reports expire after 24 hours. Probes never pay targets or certify paid delivery.
