x402-gated token data endpoint for CELO on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides token data for CELO via an x402-gated API. It is part of a broader platform offering dozens of endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure categories — all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/tokens/CELO` accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment on Base. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02. The platform advertises no API keys, no rate limits, and instant access — you pay per request with no subscriptions or commitments.
Documentation beyond the landing page is extremely sparse; the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The exact data returned for a token query (price, metadata, on-chain stats, etc.) is not documented and must be inferred or discovered by making a paid call.

Fit
Best for
- —Developers wanting keyless, pay-per-use token data access
- —AI agents that can settle x402 payments autonomously on Base
- —Projects needing low-friction crypto data without subscription commitments
Not for
- —High-volume use cases where $0.02/request adds up quickly compared to subscription APIs
- —Users who need detailed documentation or guaranteed SLAs before integrating

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it is operational. However, there is no OpenAPI spec, no request/response schema, no examples, and no meaningful documentation — the docs pages all show only 'Connect wallet'. The exact data returned is unknown, making this effectively a stub listing.
