It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).\n\nThe provider, lowpaymentfee.com, hosts a broader catalog of pay-per-request APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payment is handled entirely through the x402 protocol on the Base L2 network.\n\nThis specific endpoint (/api/v1/loans/61) is described only as \"Premium API Access\" with no further documentation on request parameters or response schema. The docs, pricing, and API pages on the site require a wallet connection and provide no additional technical detail. Without an OpenAPI spec, example payloads, or detailed documentation, the exact data returned by this loan endpoint is unclear.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","loan-data","json-response","post-method"],"categories":["finance","data"],"synonyms":["loan API","x402 API","pay-per-call API","USDC micropayment API","Base network API","lowpaymentfee","loan data endpoint","crypto payment API"],"warnings":["No OpenAPI or schema documentation available for this endpoint","The exact data returned by /api/v1/loans/61 is undocumented — 'Premium API Access' is the only description","All documentation pages (docs, pricing, API, README) are gated behind wallet connection and provide no content","The broader site lists many diverse API categories but none have visible technical documentation"],"endpointUrl":"https://lowpaymentfee.com/api/v1/loans/61","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/loans/61","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge, confirming it is operational.
