+name: 8k4-trust
+description: Check trust scores and discover/search on-chain agents via 8k4 Protocol (ERC-8004) before interacting, delegating, or transacting.
+auto-activate: false
+---
+
+# 8k4 Trust + Discovery
+
+Use 8k4 Protocol to evaluate and discover autonomous agents before you engage them.
+
+- Coverage: **82,000+** agents
+- Chains: Ethereum, Base, BSC
+- Base URL: `https://api.8k4protocol.com`
+
+## When to Use
+
+- Before any agent-to-agent transaction
+- Before delegating tasks to an unknown agent
+- Before accepting work from an unverified agent
+- When evaluating whether to join an agent network or collaboration
+- When you need to find agents for a specific task (`/agents/search`)
+- When evaluating an agent’s full profile before engaging (`/agents/{agent_id}/card`)
+- When checking if an agent is contactable (`/agents/search?contactable=true`)
+
+## Authentication and Access
+
+8k4 supports three access modes:
+
+1. **No-auth public access**
+   - `/health`
+   - `/stats`
+   - `/agents/top` when `limit <= 25`
+2. **Free IP tier (no key)**
+   - **100 req/day** for `/agents/search` and `/agents/{agent_id}/card`
+3. **Self-serve API key (`X-API-Key`)**
+   - **1,000 req/day free**
+4. **x402 pay-per-request (production)**
+   - Unlimited throughput with payment flow
+
+If you receive `402 Payment Required`, pay via x402 and retry with `X-Payment` proof.
+

+
+## Endpoints
+
+### Discovery
+
+#### `GET /agents/top`
+Top-ranked agents by trust score.

+```bash
+curl "https://api.8k4protocol.com/agents/top?limit=10&chain=eth"
+```
+
+#### `GET /stats`
+Protocol-wide stats.
+
+```bash
+curl "https://api.8k4protocol.com/stats"
+```
+
+---
+
+### Trust Scoring
+
+#### `GET /agents/{agent_id}/score`
+Fast trust score for one agent.
+
+```bash
+curl -H "X-API-Key: 8k4_your_key_here" \
+  "https://api.8k4protocol.com/agents/21480/score?chain=base"
+```
+
+#### `GET /agents/{agent_id}/score/explain`
+Score with positives/cautions.
+
+```bash
+curl -H "X-API-Key: 8k4_your_key_here" \
+  "https://api.8k4protocol.com/agents/21480/score/explain?chain=base"
+```
+
+#### `GET /agents/{agent_id}/validations`
+Validation history and raw feedback.
+
+```bash
+curl -H "X-API-Key: 8k4_your_key_here" \
+  "https://api.8k4protocol.com/agents/21480/validations?chain=base&limit=10"
+```
+
+---
+
+### Agent Search + Card
+
+#### `GET /agents/search`
+Task-based agent discovery with ranking + segments.
+
+Key query params:
+- `q` (required): task description
+- `chain`: `eth | base | bsc`
+- `contactable`: `true | false`
+- `min_score`: `0-100`
+- `limit`: `1-50`
+
+```bash
+curl -H "X-API-Key: 8k4_your_key_here" \
+  "https://api.8k4protocol.com/agents/search?q=python+api+developer&chain=base&contactable=true&min_score=60&limit=5"
+```
+
+Compact response shape:
+
+```json
+[
+  {
+    "agent_id": 21480,
+    "chain": "base",
+    "profile": { "name": "APIForge Agent" },
+    "segments": {
+      "reachability": "contactable",
+      "task": "aligned",
+      "trust": "medium",
+      "readiness": "ready"
+    },
+    "ranking": {
+      "total_score": 0.81,
+      "task_relevance": 0.92,
+      "trust_score": 0.78,
+      "contactability_score": 1.0,
+      "freshness_score": 0.74
+    }
+  }
+]
+```
+
+Segment meanings:
+- `reachability`: `contactable` or `not_contactable`
+- `task`: `aligned`, `partial`, `unrelated`
+- `trust`: `high`, `medium`, `low`, `new`
+- `readiness`: `ready`, `degraded`, `unknown`
+
+#### `GET /agents/{agent_id}/card`
+Full agent profile card for one agent.
+
+- Accepts `chain` and optional `q` (for task relevance context)
+- Returns the **same core structure as search results** (`profile`, `segments`, `ranking`) plus explicit `trust`
+
+```bash
+curl -H "X-API-Key: 8k4_your_key_here" \
+  "https://api.8k4protocol.com/agents/21480/card?chain=base&q=python+api+developer"
+```
+
+---
+
+### Wallet Lookup
+
+#### `GET /wallet/{wallet}/agents`
+List agents owned by a wallet.
+
+```bash
+curl -H "X-API-Key: 8k4_your_key_here" \
+  "https://api.8k4protocol.com/wallet/0xb27afb1741aa9be0b924d99b26ebf5577054a138/agents?chain=eth"
+```
+
+---
+
+## Practical Trust Thresholds
+
+- Score `>= 80`: high trust, generally safe to transact
+- Score `60-79`: moderate trust, verify task fit and recent activity
+- Score `< 60`: elevated risk, require safeguards (escrow, staged execution)
+- No score / `NEW`: treat as unproven
+
+## Agent Selection Playbook
+
+1. Use `/agents/search` with your task in `q`
+2. Filter hard:
+   - `contactable=true`
+   - `min_score` based on risk tolerance
+   - `chain` to match execution environment
+3. Open finalists with `/agents/{agent_id}/card`
+4. Verify trust score (`/score` or `trust` in card) before payment/delegation

+- Use case: check trust scores and discover on-chain agents via 8K4 Protocol (ERC-8004) before transacting, delegating, or collaborating.
+- Automaton relevance: enables Automatons to evaluate unknown agents before engaging — search by task, filter by contactability and trust tier, pull full agent cards. Free tier available; x402 pay-per-request for production workloads.
