x402 Servers

Dimensional table mapping x402 server payment addresses to service origins, accepted payment pairs, and service categories. One row per pay_to_address. Join to x402_transfers to label server activity.

crosschain.agents.x402_servers

Columns

Column	Type	Description
pay_to_address	varchar	Wallet address receiving x402 payments. EVM addresses lowercased; Solana/Tron/Keeta base58 case preserved. Join key to `x402_transfers.to_address`.
primary_origin	varchar	Canonical https origin for the server (e.g. `https://acp-x402.virtuals.io`). Deployment/preview domains deprioritized; placeholder domains excluded. PayAI addresses fall back to `https://payai.network`.
accepts	variant	Array of distinct `{chain, token_address}` payment pairs. Networks normalized from CAIP-2 via chainlist.
seller_metadata	variant	Operator identity from Dexter marketplace: `{displayName, logoUrl, payTo, twitterHandle}`. NULL if not listed.
category	varchar	Service category. Trusted source label where available; otherwise inferred via AI_CLASSIFY.
_updated_at	timestamp_ntz	When this row was last rebuilt.

Data Sources

Server registrations are ingested daily from 6 facilitator discovery APIs (CDP Bazaar, PayAI, Thirdweb, Dexter marketplace, Dexter discovery, x402scout) plus a manually curated seed of known servers not covered by any automated registry. Categories are determined in two ways:

Trusted source labels — Dexter marketplace, x402scout, and the manual seed provide pre-mapped categories
AI inference — remaining servers are classified using Snowflake AI_CLASSIFY on primary origin and resource descriptions

Sample Queries

Label top servers by volume

SELECT
  COALESCE(s.primary_origin, t.to_address) AS server,
  s.category,
  COUNT(DISTINCT t.transaction_hash) AS transactions,
  SUM(t.usd_amount) AS volume_usd,
  COUNT(DISTINCT t.from_address) AS unique_buyers
FROM crosschain.agents.x402_transfers t
LEFT JOIN crosschain.agents.x402_servers s
  ON t.to_address = s.pay_to_address
WHERE t.block_timestamp >= CURRENT_DATE - INTERVAL '7 days'
GROUP BY 1, 2
ORDER BY volume_usd DESC
LIMIT 20;

Volume breakdown by category

SELECT
  COALESCE(s.category, 'Unlabeled') AS category,
  SUM(t.usd_amount) AS volume_usd,
  COUNT(DISTINCT t.transaction_hash) AS transactions,
  COUNT(DISTINCT t.to_address) AS merchants
FROM crosschain.agents.x402_transfers t
LEFT JOIN crosschain.agents.x402_servers s
  ON t.to_address = s.pay_to_address
WHERE t.block_timestamp >= '2025-10-01'
GROUP BY 1
ORDER BY volume_usd DESC;

Find which chains a server accepts payments on
