x402

The crosschain.agents schema provides analytics for the x402 micropayment protocol across all supported chains. x402 enables AI agents and developers to pay for API calls with USDC — no API key, no registration, just a wallet.

Available Tables

Table	Description
x402_transfers	Individual x402 token transfer events across all chains
x402_metrics_daily	Daily aggregated metrics by chain and facilitator
x402_overview	Lifetime and rolling window (7d/30d/90d) metrics
x402_servers	Server registry — maps payment addresses to service origins, categories, and accepted tokens
x402_facilitators	Facilitator registry across all chains

Key Concepts

Facilitators

Facilitators are entities that process x402 payments on behalf of users. Each facilitator has:

A unique identifier (e.g., coinbase, polygon)
One or more wallet addresses per chain
Supported tokens (typically USDC)
Access type (public, gated, or gated_paid)

Transfer Context

In x402 transfers:

from_address - The buyer (paying for API access)
to_address - The seller (API provider receiving payment)
transaction_from_address - The facilitator processing the payment

Sample Query

SELECT 
  chain,
  activity_date,
  SUM(total_volume_usd) AS total_volume_usd,
  SUM(transfer_count) AS total_transfers
FROM crosschain.agents.x402_metrics_daily
WHERE activity_date >= CURRENT_DATE - INTERVAL '7 days'
GROUP BY chain, activity_date
ORDER BY activity_date DESC;
