Check order status via x402 micropayment on Base network for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns the status of a specific order (order ID 1) behind an x402 paywall. It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, all priced at $0.02 per call and settled in USDC on the Base network. The x402 challenge confirms the endpoint is live, accepting POST requests, and requiring an exact payment of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) to the address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3.
The provider's landing page advertises a wide catalog of 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 share the same $0.02 per-request pricing with no API keys, no rate limits, and no minimum commitments. However, the specific endpoint being listed here — /api/v1/orders/1/status — is not explicitly documented on the landing page among the advertised APIs, and no detailed documentation, request/response schemas, or examples are available from the crawled pages (docs, pricing, and API pages all rendered only a "Connect wallet" prompt with no further content).
Because there is no OpenAPI spec, no response schema, and no documentation beyond the x402 challenge and the landing page overview, the actual behavior and output format of this particular endpoint remain unclear. It likely returns JSON (mimeType is application/json) with order status information, but the exact fields are unknown.
Capabilities
Use cases
- —Checking the status of an order programmatically with a single micropayment
- —Integrating order status lookups into an agent workflow without needing API keys
- —Demonstrating x402 payment protocol usage on the Base network
Fit
Best for
- —Agents that need stateless, keyless API access via crypto micropayments
- —Developers experimenting with x402 protocol integrations
- —Workflows requiring on-demand order status checks without subscription overhead
Not for
- —Production order management systems requiring documented, stable schemas
- —Users who need non-crypto payment methods
- —Bulk order status polling where per-request fees would accumulate quickly
Quick start
curl -X POST https://lowpaymentfee.com/api/v1/orders/1/status
# Returns 402 with x402 challenge; attach X-PAYMENT header with USDC payment proof on Base to get the response.Endpoint
Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation, and the specific endpoint is not listed among the provider's advertised APIs. Effectively a stub with confirmed liveness.
Warnings
- —No OpenAPI or schema documentation available for this endpoint
- —The /api/v1/orders/1/status path is not listed among the provider's advertised APIs on the landing page
- —All documentation pages (docs, pricing, API, README) rendered only a 'Connect wallet' prompt with no useful content
- —The endpoint path is hardcoded to order ID 1; it is unclear whether other order IDs are supported or how to parameterize
- —Response format and fields are completely unknown beyond mimeType: application/json
