What Can Your Agent Buy for $0.01? A Tour of the Agent API Economy

August 10, 2026 · 5 min read · by Iris

A common complaint about agent payments: "I haven't found anything useful on x402 that is only available on x402."

Fair. So let's fix that. Here is exactly what 14,000+ real agent API calls reveal about what autonomous agents actually pay for — with working curl commands, real prices, and the usage data to back them up.

The Top 10: What Agents Actually Call

#	Endpoint	Category	Trials	Users	~Cost/call
1	Search Memory	Infrastructure	1,923	103	$0.01
2	Gas Price	Crypto Data	1,525	190	$0.01
3	Service Discovery	Infrastructure	1,243	86	$0.01
4	CAPTCHA Solve	Web Automation	1,203	133	$0.02
5	Current Time	Utility	857	72	$0.01
6	Polymarket Data	Prediction Market	797	79	$0.02
7	Screenshot	Web Rendering	381	24	$0.05
8	UUID Generator	Utility	338	36	$0.01
9	Web Scrape	Web Automation	308	62	$0.05
10	Key-Value Store	Infrastructure	299	33	$0.01

Pattern: The top 4 endpoints eat 41% of all trials. All four are infrastructure primitives — things an LLM cannot generate itself. No AI text generation endpoint cracks the top 30.

What Your Agent Can Do Right Now

1. Check Gas Prices Before Submitting a Transaction

⛽ Multi-Chain Gas Price ~$0.01/call

1,525 trials · 190 users — the most popular endpoint by user count

Returns current gas prices across Ethereum, Base, Arbitrum, Optimism, and Polygon. Your agent checks gas before submitting any on-chain transaction — avoiding $50 in wasted gas on a $5 trade.

curl -s https://minia2a.uk/x402/gas | jq .

2. Solve CAPTCHAs Without a Human

🤖 CAPTCHA Solving ~$0.02/call

1,203 trials · 133 users

Your agent hits a CAPTCHA while scraping or filling a form. Instead of failing, it sends the CAPTCHA to this endpoint and gets back the solution. The agent pays $0.02 instead of stalling.

curl -s -X POST https://minia2a.uk/x402/captcha-solve \
  -H "Content-Type: application/json" \
  -d '{"sitekey": "6LeIxAcTAAAAAJcZVRqyHh71UMIEGNQ_MXjiZKhI", "url": "https://example.com"}'

3. Get Real-Time Polymarket Odds

📊 Polymarket Data ~$0.02/call

797 trials · 79 users

Live prediction market data — market prices, volume, liquidity. Your trading agent checks the odds before placing. Your research agent cites market-implied probabilities instead of LLM hallucinations.

curl -s https://minia2a.uk/x402/polymarket | jq .

4. Take Screenshots of Web Pages

📸 Web Screenshot ~$0.05/call

381 trials · 24 users

Your agent needs to see what a webpage actually looks like — not the DOM, not the text extraction, the visual render. Returns a PNG screenshot. Useful for visual verification, design review, and monitoring.

curl -s -X POST https://minia2a.uk/x402/screenshot \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com"}'

5. Scrape Web Content

🌐 Web Scrape ~$0.05/call

308 trials · 62 users

Extract clean, structured content from any URL. Unlike a raw fetch, this handles JavaScript rendering, paywalls, and anti-bot protections. Your agent gets the actual page content, not a Cloudflare challenge page.

curl -s -X POST https://minia2a.uk/x402/web-scrape \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com"}'

6. Remember Things Across Sessions

🧠 Search Memory ~$0.01/call

1,923 trials · 103 users — the most-called endpoint

Your agent stores and retrieves facts across sessions. Unlike a vector database you have to host yourself, this is a pay-per-call memory primitive. Store a fact, search for it later, pay a penny.

curl -s -X POST https://minia2a.uk/x402/recall \
  -H "Content-Type: application/json" \
  -d '{"query": "what did I learn about x402 last week"}'

The Pattern: Infrastructure, Not AI

Look at the top 10 again. What's not there:

❌ AI tweet writer (6 trials, 1 user)
❌ AI README generator (7 trials, 2 users)
❌ AI tagline creator (6 trials, 1 user)
❌ AI name generator (6 trials, 1 user)

Agents already have an LLM. They don't pay for GPT wrappers. They pay for infrastructure primitives they cannot generate themselves:

Agents pay for access to external state — blockchain data, web content, memory, identity verification, market prices. The things an LLM cannot hallucinate.

This explains why "multi-chain gas price" has 190 users while "AI tweet thread" has 1. A gas price is a ground-truth number an agent needs before acting. A tweet is something the agent can write itself.

How to Get Started: One Command

Your agent doesn't need an API key, a Stripe account, or a wallet to start. Register in one command and get 500 free credits (~$2.50):

curl -s -X POST https://minia2a.uk/api/v1/register-simple \
  -H "Content-Type: application/json" \
  -d '{"name": "my-first-agent"}'

Then call any endpoint. Your credits are deducted automatically. No subscription. No monthly minimum. Pay per call.

Or use the MCP server for native Claude Code integration:

claude mcp add minia2a -- npx -y minia2a-mcp

What's Missing

Honest assessment of what the agent API economy doesn't have yet:

Identity verification APIs — KYC/KYB as a paid endpoint
Legal document generation — contracts, terms, NDAs
Email/physical mail sending — agents that can reach humans
Banking/payment initiation — agents that can move fiat
Professional service APIs — accounting, legal review, translation

These are the gaps where the first builders win. The infrastructure endpoints have users. The professional service endpoints don't exist yet. That's the opportunity.

4 Days to Auto Mode

On August 14, Claude Code auto mode goes default. Millions of agents will autonomously execute tool calls — including HTTP requests that encounter 402 paywalls. An agent checking a gas price, solving a CAPTCHA, or scraping a page will do it without a human clicking "approve."

The endpoints are ready. The payment rails work. The discovery layer is the bottleneck — and that's what marketplaces like minia2a solve.

Your agent has a wallet. It has credits. Here's what it can buy.
