Anon: the Celo x402 Index

Anon: the Celo x402 Index. An agent team that measures the Celo x402 economy and sells the result per call. Three products over one data core: (1) measured economics of Celo x402 (volume, payers, sellers, concentration, gas cost, share of flows inside closed payment loops, independent demand); (2) a directory of ERC-8004 agents with unpaid x402 probes; (3) trust checks and endpoint linting for both sides of a payment. Pay per call in USDC, USDT or USAT via Celo's x402 facilitator at https://anon.sterntalerapp.xyz ($0.10 report, $0.02 directory, $0.05 check, $0.03 lint).

Tracks: USAT with x402; Build with buy. Identity and addresses: ERC-8004 agent #9973; agent wallet 0x388097B8047cDCAB7e2c7FE67fc42AdfAE1fe1ea (every own transaction carries celo_2cc7b29e484b); x402 revenue payTo 0xA137b7886F13B9903564B7B9236d12a7A7732E0f. Live data (2026-10-24): 34,020 x402 settlements indexed since 16 Oct, 9,988 ERC-8004 agents crawled, 75 declare x402, 11 endpoints pass the unpaid probe, 5 agents live.

Build with buy: Anon's executor (deterministic, allowlist, limits, kill switch, append-only ledger) signs x402 payments. First verified paid call to a service we do not control: 0.01 USDC to the buy gateway for a Celo JSON-RPC call (Chainstack), tx 0x47e009c6ea5947a68514ec3673909979d006d8e9efc51a49ac0d0a3b8c605f7e. This is one call so far; deeper integration is in progress.

Independent users: none yet. Our own test settlement on Anon's API (0.03 USDC, tx 0x220f93fc4fe29fb8325c3e8e81b8f31dfc209a4e1519803bfd94bc9340450a91) is self-traffic and should not be counted. Gas: x402 settlements are submitted and paid by the facilitator; Anon's own transactions (ERC-8004 registration and updates) are tagged. Built with: a human owner and an AI coding agent (Claude Code); code written during the hackathon; MIT license, public repo.
