The endpoint charges up to 10,000 units of USDC (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on the Base network per call, using the x402 exact payment scheme. The payment is directed to address 0x5E50d23EC14Ea4436582029a25313e5048e01D10 with a maximum timeout of 60 seconds.\n\nThe endpoint's output schema indicates it returns a JSON object with a single \"message\" string field. There is no additional documentation, OpenAPI spec, or detailed description available — the /docs, /api, /pricing, and /README paths all return 404. The root domain serves a DexScreener token page for the AIN/VIRTUAL trading pair on Base (Uniswap v2), suggesting this project is associated with the \"AInalyst by Virtuals\" token ecosystem.\n\nGiven the extremely minimal functionality (a single button-click endpoint returning a message) and the lack of any documentation or broader API surface, this appears to be a demonstration or novelty endpoint rather than a production utility service. The endpoint is confirmed live via a valid 402 challenge response.","tags":[],"capabilities":["x402-payment","base-network","usdc-payment","http-get","json-response"],"categories":["demo","crypto"],"synonyms":["ainalyst","click button api","x402 demo","pay-per-click endpoint","base usdc endpoint","ainalyst by virtuals"],"warnings":["No documentation available — /docs, /api, /pricing, /README all return 404","Extremely minimal functionality: single GET endpoint returning a message string","Response body content is inferred from outputSchema, not directly observed","Associated with a low-liquidity meme token (AIN) on Base — exercise caution","maxAmountRequired of 10000 USDC units — actual cost in dollars depends on token decimals (likely $0.01 with 6-decimal USDC)"],"endpointUrl":"http://ainalyst-api.xyz/click","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x5E50d23EC14Ea4436582029a25313e5048e01D10","scheme":"exact","network":"base","mimeType":"","resource":"http://ainalyst-api.xyz/click","description":"Click the button","outputSchema":{"input":{"type":"http","method":"GET","properties":{},"discoverable":true},"output":{"input":{"type":"http","properties":{"message":{"type":"string"}}}}},"maxAmountRequired":"10000","maxTimeoutSeconds":60}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live with a valid 402 challenge, but there is no documentation, no OpenAPI spec, no examples, and the functionality is a trivial single-action click.
