Pay-per-call geocoding API on Base network via x402, $0.02/request in USDC.
What it does
This endpoint provides a geocoding utility accessible at /api/v1/utils/geocode on lowpaymentfee.com. It uses the x402 payment protocol, accepting USDC payments on the Base network at $0.02 per request (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to access the service.
The endpoint accepts POST requests and returns application/json responses. Based on the endpoint path and the provider's listing description ("Geocoding"), it converts addresses or place names into geographic coordinates (latitude/longitude) or performs reverse geocoding. However, no detailed API documentation, request schema, or response schema was found in the crawled material — the docs, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content.
The provider (lowpaymentfee.com) hosts a broader suite of APIs across data/analytics, AI/ML, finance/Web3, and infrastructure categories, all priced at $0.02 per request with the same x402 payment mechanism on Base. The geocoding endpoint is part of the "Infrastructure" utilities group.
Capabilities
Use cases
- —Converting street addresses to latitude/longitude coordinates for mapping applications
- —Enriching location data in automated pipelines without managing API keys
- —Agent-driven geocoding where per-call crypto payment is preferred over subscriptions
Fit
Best for
- —AI agents needing on-demand geocoding without credential management
- —Low-volume or bursty geocoding workloads where pay-per-call is cost-effective
- —Developers who prefer crypto-native (USDC on Base) payment rails
Not for
- —High-volume batch geocoding where per-call pricing becomes expensive
- —Applications requiring detailed documentation or SLA guarantees
- —Users without access to USDC on the Base network

Quality
The x402 challenge is live and confirms pricing and payment details, but no API documentation, request/response schema, or usage examples are available. The endpoint's exact input format and response structure are inferred from the path name only.
Warnings
- —No API documentation found — docs page returns only 'Connect wallet' with no content
- —Request and response schemas are entirely inferred; no official specification available
- —No example responses or error codes documented
