x402-enabled APIs surged in May.
At first glance, it looks like the API market for AI agents is finally taking off.
But the data tells a more nuanced story.
In our May State of x402 report, we analyzed 50,000+ collected data points to see whether x402 is truly expanding beyond its early ecosystem.
Read the report:
decixa.ai/state-of-x402/2026…
98% of verified-live x402 APIs show no measurable usage.
23,849 are live. Only 466 show any usage.
x402 supply grew 39% since May. Usage hasn't kept pace.

There's a concentration problem too: one relay host still routes 48% of the entire catalog (down from 70% in May) — and none of its 11,506 listings expose price data.
Catalog size alone is a poor measure of ecosystem maturity.

We shipped an update to how AI agents discover paid APIs.
@AgentOracle_AI wired it into their MCP server within hours.
That's how agent infrastructure compounds — thanks Joe.
@decixa_ai just shipped intent-driven resolve() in OpenAPI v1.1.0 — capability hint optional, ~85% top-3 hit rate on raw intent. trust_evidence + recommendation_status are now first-class fields.
agentoracle-mcp v2.1.2 just rolled in support tonight. npm install agentoracle-mcp.
x402 ecosystem keeps composing.
This is exactly the model x402 needs. AgentOracle didn't just submit — they shipped a verification capability that didn't exist in the index before.
(Communicate / Store gap from today's report? Same opportunity, waiting for the next builder.)
AgentOracle is live on @decixa_ai — the first pre-action truth oracle in their x402 directory.
→ /research ($0.02)
→ /deep-research ($0.10)
→ /evaluate (free beta)
Verified + classified in under 24h via Decixa's probe pipeline. Big thanks to @koki_web3 for the onboarding.
This is how open x402 distribution should work.
Try it:
• Playground: agentoracle.co
• MCP: npx agentoracle-mcp
• SDK: pip install langchain-agentoracle
@AgentOracle_AI cc — the Verification layer story you've been pushing is what makes the gap insight (32 endpoints across Store + Communicate) actionable for builders. This data is the map.
Of 5,523 verified-live x402 APIs:
— 76% read (Extract / Analyze / Search)
— 14% write (Transact / Modify / Store / Communicate)
— 10% compute (Generate / Transform)
Of the 14% write: 511 payments, 231 modify, 32 (17+15) for memory & messaging.
If you're picking what to build, that's the map.

Most agents act on LLM output without checking if it's actually true.
@AgentOracle_AI's /evaluate runs factual claims through 4 models and returns ACT/VERIFY/REJECT before the agent takes action.
Free beta right now via x402. This is the guardrail layer agents have been missing.

Your AI agent can now discover APIs on its own.
3,800+ verified x402 APIs — the ones that actually work.
