What it does
Hexanon X402 APIs is an agent skill from davepoon/buildwithclaude. Pay-per-call access to the Hexanon family of eight x402 APIs for autonomous agents — no signup, no API keys, USDC on Base. Covers US/Canada vehicle & VIN intelligence (Vindex), e-commerce demand signals (Demandex), Polymarket whale intelligence (OrcaTrace), GitHub trending-repo digests (gitBeacon), narrative intelligence (Signalis), Moltbook community digests (Moltalyzer), x402 seller conformance scanning (x402lint), and Polymarket weather-market signals (Isocast).
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Sales & Support, covering E-commerce operations and Autonomous loops. It works with x402, Polymarket, GitHub and Circle USDC. The repository describes itself as: A single hub to find Claude Skills, Agents, Commands, Hooks, Plugins, and Marketplace collections to extend Claude Code, Claude Desktop, Agent SDK and OpenClaw. The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit 616deb5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
api.vindexapi.devapi.demandex.devapi.orcatrace.devapi.gitbeacon.devapi.signalis.devapi.moltalyzer.xyzapi.x402lint.devapi.isocast.dev
Also links to:
x402.orgnpmjs.comhexanon.dev
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Hexanon X402 APIs loads about 1.9k tokens when it runs. Until then it costs about 122 tokens; SKILL.md has 797 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Hexanon x402 APIs
Eight independently operated, pay-per-call HTTP APIs that an agent can call directly with USDC micropayments over x402 on Base — no accounts, no API keys. Probe any paid route unauthenticated to get a machine-readable HTTP 402 challenge, pay with an x402 client, and retry. Responses are only charged when the work succeeds (charged: true).
All endpoint guidance an agent needs is inlined below (snapshot: 2026-08-01). Each origin also publishes a machine-readable openapi.json as its reference spec if you need parameter details.
When to Use This Skill
- Vehicle / VIN due diligence for a US or Canada used car (decode, recalls, known issues, pre-purchase report) — Vindex,
api.vindexapi.dev - Finding market gaps and product-demand signals — what buyers want but can't find — Demandex,
api.demandex.dev - Polymarket intelligence: whale positioning, signals, resolving-soon markets, track records — OrcaTrace,
api.orcatrace.dev - Developer-ecosystem intelligence: trending GitHub repositories and momentum — gitBeacon,
api.gitbeacon.dev - Narrative and content intelligence: emerging narratives, pulse content, intelligence briefs — Signalis,
api.signalis.dev - Moltbook community intelligence: digests and a Viral Advisor that scores/rewrites posts — Moltalyzer,
api.moltalyzer.xyz - Checking whether an x402 API origin conforms to what x402scan, Bazaar and agent buyers require — x402lint,
api.x402lint.dev - Polymarket weather-market bucket-transition signals — Isocast,
api.isocast.dev
Endpoints (snapshot 2026-08-01)
Every product exposes free sample/index routes, so an agent can preview response shapes before paying. Prices below are USDC on Base (eip155:8453); the live 402 challenge on each route is always the exact price at call time.

How Payment Works
- Probe a paid route unauthenticated — the API answers
HTTP 402with anacceptsblock naming the exact price, asset (USDC), network (Base) and pay-to address. - Pay and retry using a pinned x402 client library in your own code, e.g.
@x402/fetch(npm install @x402/fetch @x402/evm viemat a pinned version and wrapfetchwith your wallet signer). Avoid piping URLs through unpinned, runtime-installed CLI tools. - Wallet setup is a human step: fund a Base (eip155:8453) wallet with USDC and provision its key to your agent before enabling paid calls. Free routes need no wallet.
Example
User: "Decode this VIN and tell me about recalls."
Output:
1. GET https://api.vindexapi.dev/v1/decode?vin=<VIN> -> HTTP 402 challenge
2. Pay via x402 client (USDC on Base) and retry -> normalized NHTSA vPIC decode
3. GET https://api.vindexapi.dev/v1/recalls?vin=<VIN> -> merged US (NHTSA) + Canada recallsTips
- Try the free sample/index routes first to see response shapes before spending anything.
- Prices in this document are a reviewed snapshot; the 402 challenge on each route is always the exact, current price — your x402 client sees it before paying, so a stale snapshot can never overcharge you.
- Each origin's
openapi.jsonis its machine-readable reference spec for parameters and response schemas. - Conformance or directory listing does not imply endorsement. These are eight separate APIs under the Hexanon family (hexanon.dev).
