Output
Returns a ranked list of matching tools from OpenSea's registry, each with name, toolId, endpoint URL, price in USD, unique buyer count, total paid call count, trust score, and any flags (e.g. never-used, bulk-published). Also includes a summary of how many tools were scanned, found, and rejected, plus the top match's name and a plain-language note explaining filter outcomes.
Example use cases
Finding a working smart contract auditor tool
“Search the OpenSea registry for tools that can audit a Solidity smart contract for vulnerabilities — filter to only proven tools with real callers and return the top 5, max price $0.10.”
Discovering NLP sentiment analysis tools
“I need a tool from the OpenSea registry that does sentiment analysis on text — show me up to 8 options, only ones that have been actually paid for and used, with no price limit.”
Comparing token metadata lookup tools
“Find tools on the OpenSea registry that can look up NFT or token metadata — limit to 6 results, proven callers only, and drop anything over $0.03.”
Technical details
Endpoint
POSThttps://www.amnt.io/api/agent/amnt/tool-scoutWhen to prefer
Use this endpoint when an agent needs to discover functional tools on OpenSea's registry for a specific subtask and wants to avoid dead or untested listings. It is the right choice when you need trust signals (unique buyers, paid call counts) rather than raw name-matching. Prefer it over manual registry browsing or generic search when you want results ranked by real-world adoption and need price filtering to stay within budget constraints.
Side effects
- No tools match the task description — 'found' returns 0 and 'note' explains why
- All matches filtered out by provenOnly or maxPriceUsd — rejected equals scanned
- Task string too long (over 200 chars) — validation error
- limit out of range (must be 1–25) — schema validation error
- Registry temporarily unavailable — upstream error response
- Ambiguous task description returns low-relevance matches
