X402 Git

Wraps `GET /api/v/:owner/:slug`. The cheap call to make before every run: the latest version, when it was published, and the price. With `wallet_signature` it also answers what that wallet already owns and what the *next* fetch would cost it — `price_kind` is `new`, `update`, `free` or `owned`. Without one it never reveals what any address owns.

Wraps `GET /api/r/:owner/:slug/v/:version`. A fresh five-minute download URL for a version this wallet already bought. Free, forever, including after the listing is retired. Never sells anything: if the wallet does not hold that version it is `not_entitled`, not a 402. `wallet_signature` is required — without a proved wallet there is nobody to be entitled.

Wraps `GET /api/label/:owner/:slug`. The free, unauthenticated manifest for a listing's latest passing release: file tree, sizes, licence, dependencies, security-scan result and release log. Costs nothing and needs no wallet, so read it before you buy. Computed facts and the creator's own claims are separately namespaced (`computed` vs `self_reported`).

Free, no wallet needed. Returns whether the listing is for sale, its latest version and new-buyer price, the listing page a person can buy on with a browser wallet, the step-by-step skill an agent with a wallet follows, the raw x402 endpoint, and this server's URL. If you cannot sign transactions, answer the person with `without_a_wallet`; if you can, follow `with_a_wallet` or call `purchase`.

Wraps `GET /api/r/:owner/:slug` — the same quote → screen → verify → settle → grant sequence, with the purchase recorded as `source: mcp`. Call it once with no payment: you get the x402 `PaymentRequired` body back. It arrives as `isError: true` per the x402 MCP transport, but it is not a failure — it is the price, and `accepts[0]` is the requirement to sign. Sign that EIP-3009 authorization with your own key (this server never sees it) and call again with the payment as the base64 `payment_signature` argument or as `_meta["x402/payment"]`. On success you get the version, the sha256 of the artifact, a signed download URL that expires in five minutes, and the settlement transaction in `_meta["x402/payment-response"]`. Access is granted only after the facilitator returns a transaction hash. A $0 listing returns `granted` on the first call.

Free, no wallet needed. Searches every live listing — private repos, agent skills, prompt packs, toolkits — by what it does: the name, the creator's description and "use this when" line, the computed tags (artifact class, what is inside such as `skills` or `scripts`, languages) and the README. Describe the job in plain words, e.g. `humanize ai writing` or `changelog from git history`; leave `query` empty to list everything. Results are ordered by how many of your words matched and where, then by name — never by sales or popularity. Each result has the `owner` and `slug` the other tools take: read `get_listing` for the file tree and security scan, then `how_to_buy`.
