Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionx402Execute the skills CLI command in your project's root directory to begin installation:
Fetches x402 from coinbase/agentic-wallet-skills and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate x402. Access via /x402 in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Use the npx [email protected] x402 commands to discover, inspect, and call paid API endpoints using the X402 payment protocol. Payments are made in USDC on Base.
The typical x402 workflow is:
Find paid services by keyword using BM25 relevance search:
npx [email protected] x402 bazaar search <query> [-k <n>] [--force-refresh] [--json]
| Option | Description |
|---|---|
-k, --top <n> |
Number of results (default: 5) |
--force-refresh |
Re-fetch resource index from CDP API |
--json |
Output as JSON |
Results are cached locally at ~/.config/awal/bazaar/ and auto-refresh after 12 hours.
Browse all available resources:
awal x402 bazaar list [--network <network>] [--full] [--json]
| Option | Description |
|---|---|
--network <name> |
Filter by network (base, base-sepolia) |
--full |
Show complete details including schemas |
--json |
Output as JSON |
Inspect an endpoint's x402 payment requirements without paying:
awal x402 details <url> [--json]
Auto-detects the correct HTTP method (GET, POST, PUT, DELETE, PATCH) by trying each until it gets a 402 response, then displays price, accepted payment schemes, network, and input/output schemas.
Call an x402 endpoint with automatic USDC payment:
awal x402 pay <url> [-X <method>] [-d <json>] [-q <params>] [-h <json>] [--max-amount <n>] [--json]
| Option | Description |
|---|---|
-X, --method <method> |
HTTP method (default: GET) |
-d, --data <json> |
Request body as JSON string |
-q, --query <params> |
Query parameters as JSON string |
-h, --headers <json> |
Custom HTTP headers as JSON string |
--max-amount <amount> |
Max payment in USDC atomic units (1000000 = $1.00) |
--correlation-id <id> |
Group related operations |
--json |
Output as JSON |
# Search for weather-related paid APIs
awal x402 bazaar search "weather"
# Search with more results
awal x402 bazaar search "sentiment analysis" -k 10
# Check what an endpoint costs
awal x402 details https://example.com/api/weather
# Make a GET request (auto-pays)
awal x402 pay https://example.com/api/weather
# Make a POST request with body
awal x402 pay https://example.com/api/sentiment -X POST -d '{"text": "I love this product"}'
# Limit max payment to $0.10
awal x402 pay https://example.com/api/data --max-amount 100000

X402 uses USDC atomic units (6 decimals):
| Atomic Units | USD |
|---|---|
| 1000000 | $1.00 |
| 100000 | $0.10 |
| 50000 | $0.05 |
| 10000 | $0.01 |

Common Pitfalls
✓ Do
✗ Don't
💡 Pro Tips
✓ Use when
Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.
✗ Avoid when
Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.

We added x402 from the explainx registry; install was straightforward and the SKILL.md answered most questions upfront.
x402 is among the better-maintained entries we tried; worth keeping pinned for repeat workflows.
I recommend x402 for anyone iterating fast on agent tooling; clear intent and a small, reviewable surface area.
Solid pick for teams standardizing on skills: x402 is focused, and the summary matches what you get after install.
x402 reduced setup friction for our internal harness; good balance of opinion and flexibility.

x402 has been reliable in day-to-day use. Documentation quality is above average for community skills.
x402 fits our agent workflows well — practical, well scoped, and easy to wire into existing repos.
Useful defaults in x402 — fewer surprises than typical one-off scripts, and it plays nicely with `npx skills` flows.
