Real-time XRP token price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current price of XRP via a pay-per-call x402 protocol. It is part of the lowpaymentfee.com platform, which offers a broad catalog of data, AI, finance, and utility APIs all priced at $0.02 per request. Payment is settled in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The caller simply includes an X-PAYMENT header with a valid x402 payment proof.
The specific endpoint `/api/v1/tokens/XRP/price` is a POST endpoint that returns JSON. Based on the site's Finance & Web3 category (which includes price feeds, exchange rates, token quotes, and gas estimates), this endpoint likely returns a current market price for the XRP token. The x402 challenge confirms the endpoint is live, accepting x402 version 1 with the "exact" payment scheme, requiring up to 20,000 base units of USDC (i.e., $0.02) per call, with a 300-second payment timeout.
The broader lowpaymentfee.com platform also exposes AI endpoints (sentiment analysis, summarization, classification, embeddings), data/analytics endpoints, and infrastructure utilities (geocoding, validation, conversion), all at the same $0.02 per-request price point. Documentation beyond the landing page is sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no additional technical detail.
Capabilities
Use cases
- —Fetching the current XRP price for a trading bot or portfolio tracker
- —Integrating real-time XRP pricing into a DeFi application without managing API keys

- —Comparing XRP prices across sources in an aggregation pipeline
Fit
Best for
- —Developers who want pay-per-call crypto price data without subscriptions
- —AI agents that can settle x402 payments autonomously on Base
- —Low-volume or bursty workloads where flat $0.02/request is cost-effective
Not for
- —High-frequency trading requiring sub-second latency guarantees (no SLA documented)
- —Users who need historical OHLCV data or candlestick charts (endpoint appears to return spot price only)
- —Consumers without a Base-compatible USDC wallet

Quality
The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, and the docs/pricing/API pages are all empty beyond a wallet-connect prompt. The response shape and request parameters must be guessed from the URL pattern alone.
Warnings
- —No API documentation available — docs, pricing, and API pages all show only 'Connect wallet' with no technical content.
- —Request body schema and response schema are undocumented; example_request_json and example_response_json cannot be provided.
- —The platform lists many endpoints across diverse categories (AI, analytics, finance, utils) all at $0.02 — quality and reliability of each is unverified.
- —No SLA, rate-limit, or uptime guarantees are documented.
