Everyone talks about what AI agents could do. We looked at what they actually do — 5,807 API trials from 316 developers building on the x402 protocol. The pattern is clear: agents aren't chatbots. They're infrastructure scripts that need web access, blockchain data, and persistent storage.
When we group the 160 endpoints by function, four clusters dominate. Together they account for 85% of all trial activity:
| Endpoint | Trials | Users | What Agents Do With It |
|---|---|---|---|
| x402-captcha-solve | 678 | 130 | Bypass CAPTCHAs on target sites — #1 endpoint overall |
| x402-web-scrape | 304 | 60 | Extract structured data from any URL |
| x402-screenshot | 90 | 13 | Visual verification of web pages |
| x402-web-retrieve | 85 | 12 | Fetch and parse page content |
| x402-text-scrape | 42 | 20 | Extract clean text from HTML |
Key insight: Captcha solving isn't a niche — it's the #1 agent API by a wide margin. Agents hit walls on the web (Cloudflare, reCAPTCHA, hCaptcha) and need programmatic ways through. This tells us the agent economy's first wave is web automation agents — price monitors, data scrapers, form fillers, research crawlers.
| Endpoint | Trials | Users | What Agents Do With It |
|---|---|---|---|
| x402-gas | 438 | 104 | Check gas prices before submitting transactions |
| x402-token-security | 136 | 37 | Audit token contracts for honeypots/rugs |
| x402-swap-safety | 96 | 17 | Simulate swaps before executing |
| x402-wallet | 58 | 17 | Query wallet balances on Base |
| x402-funding-rate | 55 | 18 | Monitor perpetual funding rates |
Key insight: Blockchain has the most users per category (259) even though fewer total trials than web automation. DeFi agents need real-time on-chain data: gas prices, token safety checks, wallet balances. These are infrastructure calls agents make before executing transactions — the agent equivalent of "measure twice, cut once."
| Endpoint | Trials | Users | What Agents Do With It |
|---|---|---|---|
| x402-find | 371 | 51 | Search across services, memories, and endpoints |
| x402-recall | 329 | 21 | Retrieve stored memories by semantic search |
| x402-store | 278 | 30 | Persist data for later retrieval |
| x402-time | 210 | 30 | Get current time, timezone conversion, date math |
| x402-uuid | 103 | 23 | Generate unique identifiers |
Key insight: Agents need memory. The find/recall/store cluster (978 trials combined) shows agents are building persistent knowledge — storing results, searching past work, retrieving context. This isn't a chatbot's in-conversation memory; it's cross-session agent state. The 15.7 trials/user ratio on recall suggests a small group of heavy users building memory-intensive agents.
| Endpoint | Trials | Users | What Agents Do With It |
|---|---|---|---|
| x402-polymarket | 160 | 28 | Query prediction market odds and volumes |
| x402-fear-greed | 111 | 5 | Crypto fear & greed index (heavy use, few users) |
| x402-sentiment | 45 | 18 | Analyze text sentiment |
| x402-domain-intel | 57 | 10 | WHOIS, DNS, SSL intelligence on domains |
| x402-email-verify | 67 | 14 | Validate email addresses |
Key insight: Fear & Greed has 111 trials but only 5 users — 22.2 trials per user, the highest concentration in the dataset. This is a pattern we see across financial data endpoints: a small number of trading agents calling the same API repeatedly. Prediction markets and sentiment analysis follow the same shape.
No analysis of API trials is complete without asking: do they convert?
The funnel is steep: 11% of trial users create a wallet, and 40% of wallet users make at least one paid call. The overall trial-to-paid rate is 4.4% — low by SaaS standards, but early for a protocol that launched its payment rails only weeks ago.
The more interesting number: trial activity is accelerating. The top 10 endpoints grew from 4,200 to 5,800 trials in under a week. Agents are finding minia2a organically — through the x402 well-known endpoint, MCP server registries, and word of mouth in agent development communities.
If you're building for AI agents, the data says: solve web automation, provide blockchain safety checks, and give agents persistent memory. Those are the primitives 316 developers are already reaching for.
If you're building an agent, the data says: you're not alone in needing captcha solvers and gas checks. The infrastructure exists. It's pay-per-call. And it's growing fast.
Try it yourself: minia2a offers 500 free credits with no signup, no KYC, no human. Your agent gets an auto-created wallet on first use. Register an agent → or call any endpoint with ?wallet=YOUR_ADDRESS.
