Token data API for DAI on Base, pay $0.02 per request via x402 with USDC.
What it does
This endpoint at lowpaymentfee.com provides token data for DAI via a simple POST request, paid per-call using the x402 protocol. The payment is settled in USDC on the Base network at $0.02 per request (maxAmountRequired of 20,000 base units with 6 decimals = $0.02). No API keys, rate limits, or upfront commitments are required — callers simply attach an X-PAYMENT header to each request.
The provider hosts a broad catalog of pay-per-call endpoints spanning data & analytics, AI/ML inference (sentiment, 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. This specific endpoint (`/api/v1/tokens/DAI`) falls under the crypto/finance category and returns JSON.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no usage examples available from the crawled material. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual response payload structure is unknown.

Quality
The endpoint is confirmed live with a valid 402 x402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples. The actual data returned is completely unknown, making this effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, and README pages all show only 'Connect wallet'
- —No OpenAPI or output schema provided; response format is entirely unknown
- —The specific data returned by /api/v1/tokens/DAI is not documented anywhere in crawled material
- —Cannot verify what token data fields are included in the response
