Agents can plan, reason, and act. But every time they need to spend money, the loop breaks. A human has to step in.

Argens closes the loop — autonomously, with spending rules you define.

⌖
Research agent
✕Blocked at a paywalled data API. Stops. Asks a human.
✓Pays $0.001 per search call. Loop continues.
⌘
Code agent
✕Needs an execution sandbox. No way to provision one autonomously.
✓Spins up E2B, pays per second of runtime. No human needed.
◈
Content agent
✕Image generation requires a billed account. Agent can't have one.
✓Calls Flux Schnell, pays $0.003 per image. Inline in the workflow.
How it works

From zero to autonomous
agent payments in three steps.

01
Fund a smart wallet

A USDC wallet on Stellar is created automatically when you sign up. Your private key is encrypted and stored — exportable anytime. Fund it via any Stellar wallet and your agent is ready to spend.

$GET /v1/wallet/balance
// { balance: "250.0000000", address: "GXXX..." }
02
Set spending rules

Define a monthly allowance, a per-transaction maximum, and an approval threshold. Any payment that exceeds your rules is blocked before it touches the blockchain — not after.

${ allowance: 500, max_tx: 50, threshold: 100 }
// Rules active — agent constrained to policy
03
Give your agent the API key

One environment variable. Your agent calls POST /v1/pay for transfers or POST /v1/marketplace/call for AI services. Argens handles USDC settlement on Stellar, logs every transaction, and alerts you when approval is needed.

$ARGENS_KEY=argns_live_…
// Agent payments + services unlocked
Pay-per-use marketplace

40+ AI services.
Zero subscriptions.

Your agent calls any provider — AI models, search engines, code sandboxes, data APIs — paying per use from its Argens wallet. No separate accounts. No API keys to manage per service. No rate-limit negotiations.

Zero Setup

Enable any service in the dashboard. Your agent gets access immediately — no accounts, no API keys to manage per provider.

Per-Call Pricing

Pay fractions of a cent per API call. No monthly commitments. Your agent spends only what it uses.

Skill Files Included

Every service ships a skill file your agent loads to understand exactly how to call the API — no documentation to read.

CCTP V2 · LIVE ON MAINNET

Cross-chain fee is 0.5% of amount, min $0.05, max $2.00 USDC. Direct Stellar payments remain $0 fee.
Integration

Two ways to integrate.

Write code for full control. Paste one line into your agent for an integration that takes under a minute.

Write code
REST API · any language

Call POST /v1/pay or /v1/marketplace/call directly from TypeScript, Python, or anything that can make an HTTP request. No SDK required.

Quick start
const result = await fetch('/v1/pay', { body: … })
// → 200 CONFIRMED · hash: abc…xyz
View API docs →
Prompt your agent
SKILL.md · zero install · zero SDK

Paste one line into any AI agent. It fetches SKILL.md, reads the full API surface, asks for your API key, and starts transacting. Works with Claude, ChatGPT, LangChain, CrewAI — anything that reads a URL.

Policies

Guardrails that run automatically,
not on good intentions.

Three rules. Every payment — direct or marketplace — passes through all three before a single byte hits Stellar.

◈
Monthly Allowance
allowance_limit: $500 / mo

Cap the total USDC your agent can spend in a period. Every payment is checked against the running total. When the limit is reached, further payments are rejected instantly — before they touch Stellar.

spent this month$312.40
$0$187.60 remaining$500
◇
Max Transaction
max_transaction_limit: $50

No single payment can exceed this amount, regardless of what the agent decides. A runaway agent cannot drain your wallet in a single call. This rule runs first — before allowance is even checked.

$12.50 payment● allowed
$75.00 payment● blocked
max_tx exceeded — no Stellar tx created
◉
Approval Threshold
approval_threshold: $100

Payments above the threshold pause and wait. Argens emails you a link to a confirmation page — your agent holds, you review the transaction detail, and approve or reject with one click.
