How this service works
Find up to five exploratory Base USDC x402 services for a task and budget, using a refreshed partial Coinbase/PayAI catalogue, Jev advertised relevance and freshly observed matching 402 prices. Returning non-robot payer counts and service fulfillment remain unknown; these suggestions do not establish a best service.
Output
Returns up to five x402 service suggestions, each with catalogue-matched endpoint details, advertised relevance scores, and freshly observed 402 prices. Does not guarantee service fulfillment or non-robot payer counts; results are exploratory and not a definitive best-service ranking.
Example use cases
Budget-capped x402 API discovery
“Find me up to five x402 services that can analyze Base token on-chain swap activity, and I only want ones that cost $0.01 USDC or less per call.”
Agentic workflow service scouting
“I'm building an agent that needs to diagnose failed blockchain transactions — what x402 APIs exist for that, ideally under $0.05 USDC each?”
AI task outsourcing on a micro-budget
“Recommend some x402 services from the Coinbase catalogue that could help me summarize or classify text, with a budget cap of $0.005 USDC per request.”
Technical details
Endpoint
POSThttps://kair-os.trade/x402-recommend/recommend?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to discover x402-priced micropayment APIs on Base that match a specific task and cost constraint, especially when drawing from the Coinbase/PayAI/agentic.market catalogue. Prefer over generic API directories when you specifically need live 402 price observations and USDC-denominated budget filtering.
Side effects
- Task description too vague to match any catalogue entries — returns empty or low-confidence suggestions
- Budget set too low to match any currently priced x402 services
- Catalogue partially stale — some services may have changed prices or gone offline since last refresh
- Input besoin exceeds 1200 character limit — request rejected
- budget_usdc value malformed or negative — validation error returned
