Pay-per-call premium API access on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides "Premium API Access" via the x402 payment protocol. The specific path `/api/v1/wire/115` is one of many endpoints offered by the platform, which spans categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities. All endpoints on the platform are priced at $0.02 per request, paid in USDC on the Base network with no API keys, rate limits, or commitments required.
The x402 challenge confirms the endpoint is live and accepts POST requests. Payment is settled on-chain using USDC (contract 0x8335…2913 on Base) with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). The timeout for payment is 300 seconds. The endpoint returns application/json responses.
While the platform lists a broad set of APIs (sentiment analysis, text summarization, embeddings, price feeds, geocoding, etc.), the specific functionality behind `/api/v1/wire/115` is not documented beyond the label "Premium API Access." The docs, pricing, and API pages all appear to require a wallet connection and provide no further technical documentation. There is no OpenAPI spec, no request/response schema, and no usage examples available from the crawled content.
