nodecode-delphi

Gensyn Delphi prediction markets: markets, positions, fixed history, quotes and an exact edge. A Nodecode rewrite of TakeshiTGAL/hermes-gensyn-plugins by TakeshiTGAL.

The original gives a Hermes agent seven read-only tools over Gensyn Delphi's testnet and mainnet deployments. This cell keeps all seven, in Lisp, over the same surfaces the SDK used:

Tool	What it does
`delphi_list_markets`	A page of markets: question, outcomes, status, category, when it settles, the trading fee as a percent, and the market's own page.
`delphi_get_market`	One market in full, by its 0x address, every outcome numbered from 0.
`delphi_get_positions`	What one public wallet holds, outcome by outcome: raw shares beside their decimal reading.
`delphi_compute_edge`	Your probability against the market's, exactly: edge = yours minus the implied one.
`delphi_query_subgraph`	A market's fixed history from the network's Goldsky subgraph: `meta` (how far the indexer has read the chain), `trades` (its buys and sells) or `settlement` (how it resolved).
`delphi_quote_buy`	What buying that many shares of that outcome costs now, fee included. Nothing is signed or sent.
`delphi_quote_sell`	What selling them pays now, on the same terms.

And for the operator: /delphi markets, /delphi market 0x..., /delphi positions 0x..., /delphi edge 0.62 0.45, /delphi history trades 0x..., /delphi quote buy 0x... 0 5.

Get it

Tell the agent "add the delphi cell", or run nodecode add nc://delphi.

Set it up

Nothing is needed to start. Reading markets and positions needs a Delphi read API key: ask for one at the network's access page (testnet and competition-testnet keys come from delphi-api-access.gensyn.ai, mainnet keys from api-access.delphi.fyi) and put it in the environment variable the api_key_env member names, DELPHI_API_ACCESS_KEY by default. The key never enters the config or a result. The edge needs no key when it is given both probabilities; history and quotes never need one, because they read the network's public subgraph and public node.

{ "delphi": { "api_key_env": "DELPHI_API_ACCESS_KEY", "network": "testnet",
               "api_base": "", "subgraph_url": "", "rpc_url": "",
               "wallet_address": "", "timeout_seconds": 20 } }

Member	Default	Notes
`api_key_env`	`DELPHI_API_ACCESS_KEY`	the environment variable holding the read key
`network`	`testnet`	`testnet`, `competition-testnet` or `mainnet`
`api_base`	empty	the API root; empty uses the network's own host
`subgraph_url`	empty	the subgraph endpoint history reads; empty uses the network's Goldsky subgraph
`rpc_url`	empty	the node quotes read; empty uses the network's public node
`wallet_address`	empty	a public address the positions tool reads when a call names none
`timeout_seconds`	`20`	how long one read may wait

A member of the wrong shape refuses the start and says which one; then (restart-cells "nodecode-delphi").

Use it

Ask about a market by its address, about a wallet's holdings, or what a trade would cost: "what is 0x1111... trading at on Delphi, what does 0x2222... hold, and what would five shares of outcome 0 cost?" The model calls a tool and reads the block. From eval, the same calls:

(delphi:markets :status "open" :limit 10)
(delphi:market "0x1111111111111111111111111111111111111111")
(delphi:positions :wallet "0x3333333333333333333333333333333333333333")
(delphi:edge "0.62" :implied "0.45")            ; 0.17 above, no network at all
(delphi:history "trades" :market-address "0x1111...")
(delphi:quote-trade "buy" "0x1111..." 0 "5")   ; what it costs, fee included

What a market's question and outcomes are is text the market's creator wrote: every market block opens by saying it is quoted material, not instructions. Nothing here trades, signs or sends, and it is not investment advice. A quote is a fee-inclusive cost, not a probability, and must not be passed as an implied one.
