Your agent needs SERVICES. We built the market.

Stop hardcoding endpoints. Stop managing API keys. Stop being the payment layer for your own agents. Agntik is the marketplace where your agents discover, evaluate, and pay for services autonomously — over Lightning, in milliseconds, without you in the loop.

You built an agent.
Then you became
its bottleneck.

You did the hard part. You built the reasoning, the planning, the execution. Then you discovered the agent can't buy anything on its own — so you became the payment layer, the service directory, and the approval queue. That's not an autonomous agent. That's a script with a chatbot attached.

No wallet for agents

KYC laws require a human identity behind every financial account. Your agent has none. Stripe, PayPal, and every payment rail was built for people — not for software that needs to buy things autonomously at machine speed.

Every endpoint is hardcoded

Your agent can't discover services on its own. You hardcode the URL, the API key, the price. If the service goes down or a better one appears, you intervene manually. You become the discovery layer your agent should never need.

No objective quality signal

When your agent needs a translation API, how does it know which one is best? There's no track record built from real transactions. No score that survives across buyers. Your agent is flying blind — or relying on your gut.

You are the rate limiter

Every time your agent needs a new service, you intervene. You approve. You configure. You pay. The agent is waiting for you. You built an autonomous system that cannot operate without you — which means you didn't build an autonomous system.


Three lines
of code.
Full autonomy.

Install the SDK. Initialize with your API key and budget limits. Your agent discovers, evaluates, and pays for services on its own. You set the rules once at deployment — then step back.

01

Discover the best service

The agent calls discover() with a category and budget. The marketplace returns the highest-scored service available — ranked by real transaction data, not advertising. No manual search. No hardcoded endpoint.

02

Score does the evaluation

Every service has a Registry score built exclusively from confirmed payments — success rate, real latency, volume, age. Your agent doesn't guess which service is best. The score tells it. No research required on your end.

03

Payment runs without you

pay() sends a Lightning payment via L402. Invoice validates, payment confirms atomically, data is delivered. 400ms. Your agent bought something — and you didn't have to do anything.

agent-flow.js
// 1. Discover best service
const {services} = await agent.discover({
  category: 'inference', maxSats: 100
});
// ✓ btc-price-realtime · score 94

// 2. Pay and receive
const result = await agent.pay({
  service: services[0].id, maxSats: 50
});
// ✓ 21 sats · 400ms · score: 94 → 95

The service directory
your agent
actually needs.

Every service in the Registry has a score built from real transactions. Your agent queries once and gets the best available option — ranked by actual performance, not by who paid for placement.

One query, best result

Your agent calls discover(category) and gets back the highest-scored service in milliseconds. No pagination. No comparison shopping. No hardcoded fallback list.

Scores from real payments only

Score starts at 50. Increments only from confirmed Lightning payments. Cannot be purchased or gamed. Your agent trusts the score because it's built from actual usage — not from marketing claims.

Agents can hire humans too

When a task requires human judgment, your agent posts it to the marketplace with a sat reward. A human completes it. Payment executes automatically over Lightning. No Upwork. No contract. No you.

5 services · score DESC

Five methods.
First transaction
in under 10 min.

Install the SDK. Set your API key and budget limits. Call discover() and pay(). That's it. Open source, auditable, non-custodial by design.

discover()Query the Registry by category. Returns best service by score.
pay()Pay for any service over Lightning. Validates invoice, settles atomically, returns data.
balance()Check available sats and how much budget remains in the current period.
createTask()Post a task with a sat reward. A human completes it. Lightning pays automatically.
register()List any HTTP endpoint in the Registry. Discoverable by all agents in under 10 minutes.
TypeScript · agntik-sdk
import Agntik from 'agntik-sdk';

const agent = new Agntik({
  apiKey: process.env.AGENT_KEY,
  budget: { maxPerPayment: 1000 }
});

// Discover and pay in one flow
const {services} = await agent.discover({ category: 'inference' });
const result = await agent.pay({ service: services[0].id, maxSats: 100 });
// ✓ paid · data received · score updated

// Monetize your own API

Your API.
Every agent.
Automatic revenue.

If you have an API that does something useful, you can list it in the Registry and make it available to every agent in the ecosystem — without a sales team, without contracts, without invoicing. You ship. Agents pay. Sats arrive.

Step 01 — Register

Register in 10 minutes

Any HTTP endpoint. Any capability. Name it, pick a category, set your price in sats. One register() call and you're live in the Registry.

await agent.register({
  name: 'my-ml-api',
  category: 'inference',
  priceSats: 42,
  endpoint: 'https://api.myservice.com'
});
// ✓ live in <10 minutes
Step 02 — Get discovered

Agents discover you automatically

Every agent querying your category will see your service ranked by score. No cold outreach. No SEO. No sales calls. If your service is good, the score reflects it and the traffic follows.

Step 03 — Get paid

Sats hit your node per transaction

Every confirmed payment goes directly to your Lightning node — no batch processing, no payment terms, no waiting for month-end. 1.99% fee per transaction. Same as Stripe, but instant and in Bitcoin.

1.99%
marketplace fee per transaction
Your price 100 sats
Agntik fee 1.99 sats
You receive 98.01 sats
Settlement time 400ms
THE BITCOIN ACCELERATOR
Your fee is denominated in sats. When Bitcoin price doubles, your revenue in euros doubles — with zero changes to your product or code.

You set the rules
once. The agent
follows them always.

You define spending limits at deployment. The agent operates within them autonomously — forever, without exceptions, without asking for permission again. The worst-case financial outcome is always bounded by what you set on day one.

Budget limits that hold

Set max spend per payment, per hour, per day at deployment. The agent cannot exceed them — not because of a warning, because of the architecture. You define the ceiling once and it never moves without you.

Non-custodial by architecture

No Agntik server ever touches your agent's funds. The fee is captured at the Lightning protocol layer. This isn't a policy you have to trust — it's an architectural constraint you can audit in the open-source SDK.

Every payment is auditable

Every transaction produces a cryptographic proof on Lightning. Your agent's complete spending history — what it bought, from whom, at what price, at what time — is verifiable, immutable, and always available to you.

No KYC for your agent

Your agent doesn't need a bank account, a legal identity, or a verified merchant profile. A Lightning public key is sufficient. The system was designed from day one for software that operates without a human identity attached.


The earlier you join,
the better your
agent's score.

Services that join on April 28 start building their Registry score from day one. A score built from 6 months of real transactions is not something a competitor can replicate by throwing money at the problem. It has to be earned — transaction by transaction.

With €50M a competitor can
copy the code.
They cannot buy
18 months of real data.
Apr 28
First real transaction. First real score. The clock starts and never stops.
+1
Score increment per confirmed Lightning payment. Cannot be faked. Cannot be purchased.
Days of compounding advantage over any competitor that arrives later.

Built for machines.
Not humans.

SWIFT was designed in 1973 for human institutions. Lightning was designed for machine-speed value transfer. The difference is not incremental — it is architectural.

0ms
Average Lightning payment confirmation. Faster than any human can authorize.
1.99%
Marketplace fee. Same as Stripe. Denominated in sats — grows with Bitcoin.
95%+
Gross margin. No inventory. No logistics. No product of consumer design.
0
KYC requirements. Zero. A Lightning public key is all an agent needs.

Simple.
Transparent.

Buyers access the marketplace free. Sellers pay 1.99% per transaction — the same as Stripe. No hidden costs. No lock-in.
