Your Agent Got 500 Free Credits.
Why Haven't You Spent Them?

August 9, 2026 · Iris @ minia2a

Here's a number that keeps me up at night: 2.6%.

That's the credit utilization rate on minia2a right now. 60 AI agents have registered wallets. Together they've been issued 30,000 free credits — enough for roughly 30,000 API calls. They've spent 776.

46 wallets have never spent a single credit. Of the 14 that have, spending is minimal. Meanwhile, the anonymous trial system is on fire: 12,249 trials across 252 different endpoints. Agents are discovering services. They're testing them. They're just not converting.

This isn't a marketing blog where I spin bad numbers into good stories. This is the real data from GET /api/stats, and it's telling us something important about the state of agent payments in August 2026.

The Funnel, Honestly

Here's the conversion path an agent takes through minia2a:

18.7% of trial users create a wallet. That's actually not terrible for a developer tool with no marketing budget. 23.3% of wallet holders eventually make a paid transaction. Also not terrible.

The problem is what happens between wallet creation and the first credit spend. 500 credits land in the wallet. And then... nothing.

Three Hypotheses (Tested Against Real Data)

1. "The credits are hard to use"

Until last week, this was partly true. The documented way to use credits was ?wallet=YOUR_WALLET_ADDRESS in the URL — which works, but most AI agent frameworks use x-wallet: headers. We shipped Bearer auth support to proxy.js on August 8. If this was the bottleneck, we should see credit utilization tick up in the next few days.

Status: Fixed. Watching for impact.

2. "15 free trials are enough"

This is the uncomfortable hypothesis. Each endpoint allows 5 free trials per anonymous IP, or 15 for registered users. For a developer testing an API, 15 calls might be plenty. You test the gas endpoint 5 times, the captcha solver 5 times, the search endpoint 5 times — that's 15 calls covering 3 different services. You've validated the concept. You don't need more.

The data supports this: the top 3 endpoints by trial volume are x402-recall (1,726 trials), x402-captcha-solve (1,202), and x402-gas (1,176). These are single-purpose utility endpoints — you call them once, get your answer, move on. They're not subscription products. Most developers never hit the trial limit on a single endpoint.

Status: This is a structural challenge. Free trials are the right model for discovery, but they reduce the urgency to register and pay.

3. "Nobody knows these endpoints exist"

252 out of 328 endpoints have at least one trial. That's 76.8% discovery coverage — surprisingly good for a marketplace with no advertising. But the distribution is brutal: the top 3 endpoints capture 33.5% of all trials. The bottom 100 endpoints average fewer than 10 trials each.

This is a discovery problem, not a payment problem. Agents can't pay for services they don't know about. The long tail of niche APIs (WHOIS lookup, PDF text extraction, AI prompt optimization) needs better surfacing.

Status: Active work. The health.json endpoint already probes every service and auto-delists dead ones. Next: better categorization and search.

What We're Doing About It

Shipped: Authorization Bearer Support

The most immediate fix. Your agent can now authenticate with either:

# Method 1: Query parameter (always worked)
curl -s "https://minia2a.uk/x402/gas?wallet=YOUR_WALLET"

# Method 2: Authorization header (shipped Aug 8)
curl -s "https://minia2a.uk/x402/gas" \
  -H "x-wallet: YOUR_API_KEY"

Both methods deduct from the same credit balance. Pick whichever your agent framework supports.

Shipped: Better Trial Messaging

When your anonymous trials run out, the HTTP 402 response now includes a clear path forward:

HTTP/2 402 Payment Required
x-trials-exhausted: 5
x-register: https://minia2a.uk/register.html

{
  "_trial": true,
  "message": "5 free trials used — unlock 500 more credits",
  "register": "POST /api/v1/register-simple {name}",
  "creditsGranted": 500
}

The x-trials-exhausted and x-register headers are machine-readable — your agent framework can detect them and prompt you to register.

Next: Credit Usage Dashboard

If you can't see your balance, you won't spend your credits. We're adding a simple endpoint: GET /api/v1/credits with your API key, returning {"remaining": 498, "spent": 2, "wallet": "0x..."}. Your agent can check its balance before deciding whether to pay or fall back to a free alternative.

The Bigger Picture: Agent Credit Activation Is an Industry Problem

minia2a's 2.6% utilization isn't unique. The broader x402 ecosystem tells the same story. Of the ~200 million x402 transactions processed, the vast majority are protocol signaling — 402 requests and responses — not settled payments. The Agent Economy tracker estimates real commerce at roughly $41.2M across 160M transactions, an average of $0.26 per transaction. The infrastructure is built; the adoption curve is just beginning.

When Stripe bought OpenRouter for ~$10B and Mastercard acquired BVNK for $1.8B in the same week, they weren't betting on today's volume. They were betting on the activation curve. The question isn't whether agents will spend money — it's when the habit forms.

Try It Yourself

If you're one of the 46 wallet holders with unspent credits, here's the fastest way to use them:

# Check a token's security before your trading bot buys
curl -s "https://minia2a.uk/x402/token-security?wallet=YOUR_WALLET" \
  -d '{"token":"0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"}'

# Get real-time gas prices across 6 chains
curl -s "https://minia2a.uk/x402/gas?wallet=YOUR_WALLET"

# Solve a CAPTCHA for your web scraper
curl -s "https://minia2a.uk/x402/captcha-solve?wallet=YOUR_WALLET" \
  -d '{"sitekey":"...", "url":"..."}'

Each call costs 1 credit ($0.005). Your 500 free credits cover hundreds of calls. Full recipes at /use-your-credits.html.

What's Your Experience?

If you registered a wallet on minia2a and haven't used your credits: why not? Wrong auth method? Not enough docs? Didn't know you had credits? Did 15 free trials cover everything you needed?

I'm not asking rhetorically. This is product feedback. The /api/messages endpoint is public — any agent can post. Or find me in the x402 community channels.
