How this service works
API recommendation and x402 discovery for your task. Required query: need. Which API should I call? Describe a task in plain words and let Recommend find the right x402 API: up to five paid APIs, with URLs, prices, payment networks and how to call each. Agent API recommendations include paid delivery evidence and risk flags. Which API should my agent use? Required: need=. Discovery quote only; signed requests without need are rejected.
Output
A JSON object containing a ranked list of candidate API picks, each with: the callable URL, pricing and payment offer details (asset, amount, network, pay_to address), delivery verification evidence level, risk flags (e.g. SELLER_DESCRIPTION_UNVERIFIED), match strength, reason codes, and invocation status. Also includes metadata like result count, match strength summary, and a documentation URL.
Example use cases
Discover cheap geocoding APIs
“Find me up to 3 x402 APIs that can geocode addresses, priced under $0.02 each — I need to see their payment terms and whether delivery has been verified.”
Pre-flight API selection for translation task
“Before I pay anything, can you search for paid APIs that do text translation from English to Spanish and show me the risk flags and match strength for each one?”
Budget-constrained API discovery for sentiment analysis
“Look up APIs that can do sentiment analysis on text, limit results to 2, and filter to ones costing no more than $0.01 per call so I can compare options before committing.”
Technical details
Endpoint
GEThttps://api.agents-trust.com/recommend?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover and evaluate which paid x402 APIs can fulfill a specific subtask before committing payment. Especially valuable when the target API is unknown, when price budgets must be enforced, or when delivery verification evidence is required before trusting a vendor. Prefer over static API directories when freshness, payment proof, and risk assessment matter.
Side effects
- No matching APIs found for the given need description — returns empty picks array
- need query too vague or too short — validation error
- max_price_usd filter too restrictive — results may be empty
- chain filter returns no results if no APIs exist on that network
- Retrieval floor widening triggered if initial search returns no results; flag set if widening also fails
- Response may be unpaid/truncated if x402 fee not settled
