How this service works
Which x402 API should my agent call? Describe the task in plain words (need=) and get up to 5 x402 APIs ranked by relevance plus CDP Bazaar-reported 30-day usage (unique payers, repeat ratio, last call; sellers paid via other facilitators may show 0; sweeper-like usage is flagged and not rewarded), each re-checked right now for a 402 payment challenge (unless probe=0), with price, network, payTo, method, example input and risk flags. Mainnets only unless network= asks. $0.002 per call; 400/404/5xx are not charged.
Output
A JSON array of up to 5 ranked API picks, each containing: the API URL, offer details (payTo address, network CAIP-2 ID, price in USD, asset symbol), HTTP method, evidence block (usage stats: unique payers, repeat ratio, last called, 30d call count, usage source, risk flags), and a live_check block (whether checked, HTTP status, latency in ms, payment_challenge boolean). A meta block includes generation timestamp and notes.
Example use cases
Discover cheapest x402 API for translation
“Find me x402 APIs for translating text, limited to 5 results, and only show ones that cost $0.005 or less per call — I want to see their usage stats and whether they pass a live 402 check right now.”
Scout Base-network x402 APIs for image gen
“Which x402 APIs on the Base network can help me generate images? Give me the top 3 by relevance and show me repeat usage ratios and any risk flags.”
Find high-usage x402 API for news retrieval
“I'm building an agent that needs to fetch news articles — what x402 APIs exist for that? Show me up to 5, ranked by relevance, with their 30-day unique payer counts and live payment challenge status.”
Technical details
Endpoint
GEThttps://x402-recommend.agentpageread.workers.dev/recommend?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which x402-protocol API to call for a given task at runtime, rather than hard-coding a specific API. Ideal when the best tool is unknown, when you want to compare price/usage before committing to a call, or when you need to verify that a candidate API is currently live and accepting x402 payments. Prefer this over static API registries when freshness and payment-challenge verification matter.
Side effects
- 400 if 'need' parameter is missing or exceeds 300 chars (not charged)
- 404 if no matching x402 APIs are found for the described task (not charged)
- 5xx on internal/Cloudflare Worker errors (not charged)
- Empty picks array if no APIs pass the network/max_price filters
- Live 402 re-check may fail if a listed API is temporarily down (live_check.http_status != 402)
- Usage stats may show 0 if seller uses a non-CDP facilitator
