How this service works
Finds and ranks machine-payable services for an agent capability.
Output
Returns a JSON object indicating whether a matching service was found, the recommended service endpoint with its details, a list of alternative candidates, routing reasons explaining the recommendation, the number of candidates found and filtered, registry sources queried, and whether the result is cached or degraded.
Example use cases
Route to cheapest web scraping tool
“My agent needs to scrape public web pages — find me the cheapest available machine-payable service for structured web extraction, with a max latency of 3000ms.”
Discover reliable token audit service
“I'm building an agent that audits EVM tokens before trades — route me to the most reliable token security service available, optimized for quality, and cap the price at $0.01 per call.”
Find fastest crypto price API
“My trading bot needs real-time crypto prices — find me the fastest available machine-payable service for the crypto_price capability, optimized for speed with a max latency of 200ms.”
Technical details
Endpoint
POSThttps://mcp.dropenginehq.com/api/route-tool?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover and select the best machine-payable API for a given capability at runtime, especially when multiple competing services exist and you want constraint-based filtering (price, latency, reliability) plus optimization preferences. Prefer this over hardcoding service URLs when building adaptive agentic workflows that should route to the cheapest, fastest, or highest-quality provider automatically.
Side effects
- No matching service found for the requested capability (match_found: false, recommended: null)
- All candidates filtered out by constraints (candidates_after_filters: 0)
- Registry sources unavailable, returning degraded response
- Invalid capability name format (must match ^[a-zA-Z][a-zA-Z0-9_.-]*$)
- Query string exceeds 300 character limit
- Price or latency constraints out of valid range
