It is part of a broader suite of APIs offered by lowpaymentfee.com, which spans data analytics, AI/ML inference, finance, crypto, and utility services — all gated behind x402 micropayments on the Base network.\n\nThe endpoint accepts POST requests and returns JSON. Payment is settled in USDC on Base (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are advertised; access is granted per-call via the x402 payment header. The x402 challenge was successfully captured, confirming the endpoint is live.\n\nDocumentation beyond the landing page is extremely thin — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The specific data source for the MDLZ quote (real-time vs. delayed, which exchange) is not documented. Prospective users should be aware that the actual response format and data freshness are unknown.","tags":[],"capabilities":["stock-quote","market-data","x402-payment","usdc-base","per-call-micropayment","json-api"],"categories":["finance","market-data"],"synonyms":["stock price API","MDLZ quote","Mondelez stock data","equity quote endpoint","market quote micropayment","x402 finance API","pay-per-call stock API"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","All documentation pages (/docs, /api, /pricing, /README) render only 'Connect wallet' with no content","Data source and freshness (real-time vs. delayed) for the MDLZ quote are not documented","No example responses available to verify data quality"],"endpointUrl":"https://lowpaymentfee.com/api/v1/market/quote/MDLZ","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/market/quote/MDLZ","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02 USDC on Base per call), but there is no OpenAPI spec, no example request/response, no documentation of the response schema, and no information about data source or freshness.
