# ToolPick Lite by AgentGate > ToolPick Lite by AgentGate is a paid API for AI agents from api.youraitools.co, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-24). Searches merged x402 API discovery indexes to return the top 5 paid x402 API endpoints most relevant to a described capability need, ranked by relevance, usage, recency, and price. ## Facts - Endpoint: GET https://api.youraitools.co/toolpick/v1/lite?utm_source=zero.xyz - Price: $0.003/call - Payment: x402 - Status: unknown - Last checked: 2026-10-24 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/toolpick-lite-by-agentgate-611b7822 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_YFsV5PR8q2KY13AiXJlvj Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability toolpick-lite-by-agentgate-611b7822 ``` Example prompt: Search the x402 API indexes for a 'web search' capability, only show results priced at $0.01 or less on Base, and make sure at least 3 unique payers have used each one in the last 30 days. ## When to prefer this Use this endpoint when an AI agent needs to dynamically discover and select a paid x402 API for a task at runtime, rather than hard-coding a specific provider. Prefer it over manual directory browsing when you need ranked, filtered results from multiple x402 indexes simultaneously. Ideal when price, network compatibility, or proven usage (payer count) are selection criteria. Use the /v1/lite variant for a fast, low-cost discovery pass before committing to a live check. ## Known failure modes - 404 returned with no charge when no x402 resources match the need query - Stale index data if index.age_s is large or index.stale is true - Self-described listings may not accurately reflect actual API behavior or data quality - sources_failed array may indicate one or more discovery indexes were unavailable during the query - max_price or min_payers filters set too restrictively may yield zero results - Relevance scoring is keyword/semantic — niche or highly technical needs may not match well ## How this service works API search engine for AI agents (find a paid x402 API). Find the paid x402 API for a task: top 5 resources from the merged public x402 discovery indexes, ranked by relevance to your need, index-reported 30-day payers and calls, recency and price. Each result: service, resource URL, method, description, USDC price, networks, 30-day calls and payers, repeat_buyers, last called time. Filters: max_price, network, min_payers. No live check (use /v1/pick). No matches: 404, never charged. ## Output A JSON object with up to 5 ranked x402 API results matching the capability need. Each result includes: host, rank, relevance score, HTTP method, service name, networks accepted, resource URL, price in USD, 30-day call count, 30-day unique payer count, repeat_buyers flag, last_called_at timestamp, description snippet, and index sources. Also includes metadata: matched host count, index age/freshness, applied filters, total matches found, confidence level, and a disclaimer about listing provenance. Returns 404 with no charge if no matches are found. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [ "need" ], "properties": { "need": { "type": "string", "description": "The capability you need, in plain words, e.g. \"solana token safety\", \"web search\", \"pdf to text\", \"hyperliquid funding rates\" (2-200 chars)" }, "network": { "enum": [ "any", "base", "solana", "polygon", "arbitrum", "optimism", "ethereum", "avalanche" ], "type": "string", "description": "Only resources payable on this network (default any)" }, "max_price": { "type": "number", "description": "Only resources priced at or below this many USD per call, e.g. 0.01" }, "min_payers": { "type": "integer", "description": "Only resources with at least this many unique payers in the last 30 days (default 0)" } }, "description": "Search intents: find api for task, x402 api search, api discovery, paid api directory, agent tool search, best api for" } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": "object", "properties": { "need": { "type": "string" }, "tier": { "type": "string" }, "hosts": { "type": "number" }, "index": { "type": "object" }, "terms": { "type": "array" }, "filters": { "type": "object" }, "matches": { "type": "number" }, "results": { "type": "array" }, "checked_at": { "type": "string" }, "confidence": { "type": "string" }, "disclaimer": { "type": "string" }, "sources_failed": { "type": "array" } } } } } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "need": "solana token safety", "tier": "lite", "hosts": 151, "index": { "age_s": 600, "stale": false, "refreshed_at": "2026-10-23T12:59:10.247Z" }, "terms": [ "solana", "token", "safety" ], "filters": { "network": "any", "max_price": null, "min_payers": 0 }, "matches": 610, "results": [ { "host": "agent402.tools", "rank": 1, "score": 3.298, "method": "POST", "service": "Solana token risk check", "networks": [ "base", "polygon", "arbitrum", "avalanche", "optimism", "solana" ], "resource": "https://agent402.tools/api/sol-token-safety", "calls_30d": 230, "price_usd": 0.005, "relevance": 1, "indexed_on": [ "cdp" ], "payers_30d": 6, "description": "Safety verdict for one Solana token mint: a graded risk score with the concrete reasons be", "repeat_buyers": true, "last_called_at": "2026-10-23T09:12:46.000Z" }, { "host": "chain.tollkit.dev", "rank": 2, "score": 1.986, "method": "POST", "service": "Token Safety Check", "networks": [ "base", "solana" ], "resource": "https://chain.tollkit.dev/chain/check", "calls_30d": 9, "price_usd": 0.004, "relevance": 0.9, "indexed_on": [ "cdp" ], "payers_30d": 6, "description": "Token safety check (rug check) for AI agents before buying, sending or accepting a crypto ", "repeat_buyers": true, "last_called_at": "2026-10-15T07:15:50.000Z" } ], "checked_at": "2026-10-23T13:09:10.247Z", "confidence": "high", "disclaimer": "Rankings use public x402 index metadata and the index-reported 30-day call and payer counts; listings are self-described by sellers and are not endorsements.
