It is part of the $SerWTF API, a small novelty API that gates every route behind x402 micropayments on the Base network using USDC.\n\nThe endpoint accepts a POST request with no required body fields and returns a JSON object containing a \"message\" string. Payment is required via the X-PAYMENT header using the x402 \"exact\" scheme on Base mainnet, with a max cost of 5,000,000 units of USDC (0x8335…2913), which corresponds to 5 USDC given USDC's 6 decimal places. The payment timeout is 300 seconds.\n\nDocumentation is minimal — the OpenAPI spec lists four endpoints (/, /mint, /data, /mint-1000) all gated behind x402 challenges, but none include request or response schemas beyond an empty object. The API self-describes as \"the first BSC-backed API that rewards poor financial decisions built by AI.\" There is no detailed documentation, no usage examples, and no information about what the returned analytics data actually contains. Prospective callers should be aware that the actual utility and data quality of the response are unknown.","tags":[],"capabilities":["x402-payment-gated","ngmi-analytics","base-network","usdc-payment","post-endpoint","micropayment"],"categories":["crypto","data"],"synonyms":["SerWTF API","NGMI data","crypto analytics","x402 data endpoint","meme token analytics","ser-api","regret AI"],"warnings":["No response examples or detailed schema available — actual data content is unknown","API self-describes as rewarding 'poor financial decisions' — treat as novelty/experimental","5 USDC per call is relatively expensive for an undocumented endpoint","No pricing page, README, or supplementary documentation exists","Output schema is minimal: only a single 'message' string field is documented"],"endpointUrl":"https://x402.ser-api.wtf/data","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xFD3A621Db3865FC269D471BE6932c9ebA386ccF2","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://x402.ser-api.wtf/data","description":"Access insightful data for mint","outputSchema":{"input":{"type":"http","method":"POST","body_type":"json","body_fields":{},"discoverable":true,"query_params":{},"header_fields":{}},"output":{"type":"object","properties":{"message":{"type":"string"}}}},"maxAmountRequired":"5000000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge, but documentation is extremely sparse.
