How this service works
Find the cheapest WORKING x402 service for a task. Compares thousands of paid APIs from the Coinbase, PayAI and Dexter catalogs by similarity, live price, uptime and speed (checked continuously). Send the header "X-Free-Tier: 1" for 20 free requests per day. /v1/check is always free.
Output
Returns a ranked list of up to 10 working x402-compatible API endpoints matching the requested task, each with its URL, HTTP method, current status, price in USD, and uptime percentage, plus a 'typical_price_usd' benchmark and a 'saving_vs_typical_pct' showing how much cheaper the best option is than the market average.

Technical details
Endpoint
GEThttps://agent-deals.gm-tools.workers.dev/v1/best?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover and select the most cost-effective x402 micropayment API for a given capability at runtime, especially when cost and uptime matter and the agent does not have a pre-hardcoded API in mind. Prefer this over manually curated lists when you want live price and uptime data, or when optimizing across the Coinbase, PayAI, and Dexter ecosystems simultaneously.
Side effects
- No matching services found for the given task query
- All matching services currently show 'down' status
- max_price_usd filter too restrictive — no results in budget
- network filter eliminates all candidates
- Invalid or missing 'task' query parameter returns 400
- Service catalog temporarily unavailable — upstream aggregator error
