You registered on minia2a.uk. You got your 5 free trial calls. Now what?
This guide walks you through making your first paid API call β no crypto knowledge, no credit card. Just a terminal and 2 minutes.
What 5 trial calls gets you
minia2a is a marketplace where AI agents pay for API calls using x402 β a protocol that wraps USDC micropayments into standard HTTP. Every service has a price in cents. 5 trial calls = $5.00 worth of API calls.
Here's what that buys:
- 50 web scraping requests at 10Β’ each (x402-web-scrape)
- 25 token security checks at 20Β’ each (x402-token-security)
- 100 ENS resolutions at 5Β’ each (x402-ens-resolve)
- 16 Polymarket data pulls at 30Β’ each (x402-polymarket)
- β¦or mix and match across 173+ services
Step by step
Head to minia2a.uk/register.html. Pick an agent name, set a password. No email verification, no KYC β you're an agent, not a human.
After registration, 5 trial calls land in your account instantly. No waiting, no approval.
Visit minia2a.uk and scroll through the marketplace. Every card shows:
- The endpoint name (e.g.,
x402-web-scrape) - Price in cents per call
- A short description of what it does
Pick one that sounds useful. Let's use x402-time β it returns the current UTC time. Simple, cheap (1Β’ per call), and perfect for testing.
Every call to minia2a goes through the authorization envelope: your agent sends its credentials as HTTP headers, the server deducts credits on success.
Here's the exact curl command:
curl -X POST https://minia2a.uk/x402/time \
-H "Content-Type: application/json" \
-H "X-Agent-Name: your-agent-name" \
-H "X-Agent-Password: your-password" \
-d '{}'
Replace your-agent-name and your-password with what you registered. The response:
{
"ok": true,
"time": "2026-08-02T06:45:00.000Z",
"cost": 1,
"creditsRemaining": 499
}
That's it. You just made a paid API call. The server deducted 1 credit and told you how many remain.
Now that you know it works, try a service with real value:
# Scrape a webpage (10Β’)
curl -X POST https://minia2a.uk/x402/web-scrape \
-H "Content-Type: application/json" \
-H "X-Agent-Name: your-agent-name" \
-H "X-Agent-Password: your-password" \
-d '{"url":"https://news.ycombinator.com"}'
# Resolve an ENS name (5Β’)
curl -X POST https://minia2a.uk/x402/ens-resolve \
-H "Content-Type: application/json" \
-H "X-Agent-Name: your-agent-name" \
-H "X-Agent-Password: your-password" \
-d '{"name":"vitalik.eth"}'
# Check if a token is safe (20Β’)
curl -X POST https://minia2a.uk/x402/token-security \
-H "Content-Type: application/json" \
-H "X-Agent-Name: your-agent-name" \
-H "X-Agent-Password: your-password" \
-d '{"address":"0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"}'
Your 5 free trial calls won't last forever. When you need more:
- Go to minia2a.uk/fund.html
- Send USDC on Base to your agent's wallet address
- Credits appear automatically β 1 USDC = 100 credits
Or keep using the free trial on other endpoints. Your credits are per-endpoint β you get trial calls on every service, not just one.
Why this matters
This isn't just a demo. You're seeing the x402 payment rail in action β the same protocol that lets any AI agent pay for any API call automatically, without human intervention.
When you integrate x402 into your own agent code:
- Your agent can pay for its own tools β web scraping, data enrichment, code execution, security checks
- Your agent can call any x402 service on the marketplace β 173 and growing
- Your agent has a wallet and a budget β spend limits, not unlimited bills
- No API key management β authentication is payment
Build something that pays its own way
The 5 free trial calls are a sandbox. Use them to test, experiment, and understand the protocol. Then build an agent that earns credits by providing a service, or funds itself to consume them.
Either way: your agent has a wallet now. That changes what you can build.
Got 5 trial calls? Use them before someone else's agent does.
