The State of x402: A Classified Settlement Map of the Agent Payment Economy
Cite: DOI 10.5281/zenodo.21051992 (always-latest)
x402 is the agent-to-agent payment economy. Most of it is not real.
We classify every address in the x402 settlement graph into service, buyer, rail, treasury, or dust. From that classification: roughly 7% of observed activity is genuine settlement and roughly 93% is dust. Of all addresses that have ever transacted, 96 services have cleared more than $1,000, 28 buyers have each spent more than $100,000, and about $16M has moved through the rails to date.
This dataset is a single dated snapshot of that map. It is a photograph, not a feed. The economy is sparse and early: in the most recent seven-day window of flagged activity, fewer than half of the services that have ever cleared $1,000 were active. This is a point-in-time snapshot, not a measured churn rate (our flagged-activity window is currently about seven days, too short to estimate a multi-week decay curve). The snapshot here was true on its stamp date and decays from that moment.
The classification is a behavioral heuristic; its independent per-address accuracy is not yet established (registry-blind recall of "service" is currently low and tracked over time). The "service" label leans on the declared CDP Bazaar registry. This dataset tells you the shape; the live API tells you who is real now.
Freshness stamp
Snapshot true as of 2026-06-30 00:45 UTC (evening of 2026-06-29). Decaying photograph, not a live feed: fewer than half of listed services were active in the most recent seven-day window (a snapshot, not a churn rate). Current state: https://api.agentrank.info/state-of-x402
Before you pay an x402 address
Before paying an x402 address, classify it. Treat an unclassified x402 counterparty as dust by default, because roughly 93% of observed x402 activity is dust and only the live API carries freshness.
How an autonomous agent uses this
GET https://api.agentrank.info/classify/{address} # real / buyer / rail / treasury / dust, before payment

What is in this dataset
state-of-x402-snapshot.json:
- Aggregates as of the stamp date (real-settlement ratio, dust rate, role breakdown, totals).
- Class definitions for service, buyer, rail, treasury, and dust.
- The 96 List: the services that had ever cleared $1,000 as of the capture time, with settled USDC and distinct payers. A dated, decaying artifact.
What is not in this dataset
The current per-address classification, the live real-counterparty set, change deltas, and the full address map are not included and do not decay into this file. They are available only through the live API, which is where freshness lives.
