Building on Base and selling to agents via x402 means your data has to be fresh, small, and payable in one request — not a tip jar.

We shipped two gated-data micro-tools on the same fly.dev origin (beside the free Bazaar readiness check):

1) Base DeFi Snapshot — `$0.03` USDC

Teaser (free schema/sample): https://geld-machen-x402.fly.dev/product/defi-base-snapshot/teaser.json
Paid live JSON: https://geld-machen-x402.fly.dev/product/defi-base-snapshot.json Unpaid → HTTP 402, amount 30000 ($0.03), network eip155:8453.

What you get when settled: ETH+USDC balances (optional ?address=), latest base fee / block, 1–3 protocol TVL/APY proxies via public Base RPC + DeFiLlama, plus as_of, block_number, sources[], timing_ms.

2) Base Allowance Scan — `$0.02` USDC

Teaser (free schema/sample): https://geld-machen-x402.fly.dev/product/base-allowance-scan/teaser.json
Paid live JSON (needs address): https://geld-machen-x402.fly.dev/product/base-allowance-scan.json?address=0x… Unpaid → HTTP 402, amount 20000 ($0.02).

What you get when settled: notable ERC-20 allowances (USDC/WETH/USDT/DAI/cbETH ∪ Uniswap/1inch/Aerodrome/bridges) via public Base RPC Multicall3, optional Approval logs, as_of, block_number, sources[].

Still free: Bazaar readiness check

Indexed yes/nein + issue count (no Fix-JSON):

Paid Fix-JSON report is $0.05 at /product/bazaar-check/report.json?url=.

These are builder utilities for agents that need Base state without standing up their own indexer. Teaser = shape. Paid = live stamp. No signup.

Free Bazaar readiness check for x402 endpoints (then $0.05 Fix-JSON)

Shipping x402 on Base is easy. Getting indexed correctly in Coinbase Bazaar is the part that silently breaks discovery.

Problem: an endpoint can return a clean HTTP 402 and still be unindexed, mis-described, or failing discovery probes — so agents never find you.

Tool: Bazaar-Readiness-Check (geld machen)

FREE check by URL — indexed yes/no + issues found (no Fix-JSON): https://geld-machen-x402.fly.dev/product/bazaar-check.json?url=YOUR_ENDPOINT
Paid $0.05 USDC on Base — Fix-JSON report when you want the repair list: https://geld-machen-x402.fly.dev/product/bazaar-check/report.json?url=YOUR_ENDPOINT (unpaid → HTTP 402, amount 50000)

Shape teaser: /product/bazaar-check/teaser.json

This is a builder tool, not a tip SKU. Human free pack (shell/python/curl wrappers) sits next to it:

payTo: 0x524Bf56B92400BD232BF85348660B652e0DdDb2a · Base USDC · x402.

No signup. Paste a public URL. If the free check shows issues, the $0.05 report is the next step — nothing else.
