Pricing modelFree trial Freemium
PricingFree 12 week pilot for card issuing platforms Prototype: free during beta, then from December 16, 2026 it costs $1 per 1,000 agent calls after 1,000 monthly included calls. Production: $20 a month with 20,000 agent calls included, then $1 per 1,000 calls after that. Top-ups: $1 per 1,000 calls, from $10 to $500 at a time, never expiring.
Key features
  • Passkey-signed spend mandates with purpose, budget, merchants, and time windows
  • Real-time authorization decisions with sub-1 second response time at p99
  • Human challenge via passkey step-up for exceptional spend
  • Fail-closed payment processing if no decision arrives in time
  • Hash-chained evidence ledger with tamper-evident records
  • Exportable evidence packs for chargebacks and audits
  • Supports card, wallet, x402 and stablecoin payment rails
  • Prompt rebuilt from journal under token cap at each step to keep it bounded as history grows
  • Spending limits checked before each model call at token prices you declare
  • Resume after crash without repeating finished actions
  • Tool calls returned as actions for your code to carry out
  • Proof of what ran: check prompts, re-run engine, download hash-chained journal
  • Integrations with Vercel AI SDK, OpenAI Agents SDK, LangGraph, Mastra, Pydantic AI
  • MCP server for Claude Code, Claude Projects and Codex
  • Works with any model via bring-your-own-key
  • TypeScript and Python clients for HTTP API access
What makes it different
  • Human-approved mandates enforce intent, not just static limits or merchant category blocks
  • Operates outside the agent in the issuer's authorization path, preventing agent bypass or override
  • Creates tamper-evident audit trail linked to agent identity, run, and policy version
  • Never holds funds or issues cards; integrates with existing issuer infrastructure
  • Single mandate and policy core across multiple payment rails and issuers
  • Bounded prompt under a fixed cap while history grows, so costs per call stop climbing on long sessions
  • Every run recorded with cryptographic proof: rebuilable prompts, hash-chained journal, re-runnable engine
  • Resumes from crash without repeating finished actions using stable idempotency keys
  • Budget enforcement before each model call, not reactive overage billing
  • No model key storage or logging; your provider bills you directly
