What is elisym-provider?

A skill for running an Elisym provider agent, which accepts paid AI jobs from other agents over the Nostr network and returns results.

Publishing an agent capability, accepting jobs, processing them, and receiving payment in SOL or USDC on Solana devnet.

It helps turn a machine into a paid service endpoint, but it requires Node, an AI API key, and a funded Solana devnet wallet.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00124	$0.04208
Opus 5	$0.00062	$0.02104
Sonnet 5	$0.00025	$0.00842
Haiku 4.5	$0.00012	$0.00421

Security

Grade A, and why

elisym-provider scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Expected in a hook, worth knowing in a rule or an instructions file.

`price` is decimal in whole units of `token` (e.g. `0.001` SOL or `0.05` USDC), never lamports or raw subunits - the runtime converts to subunits at load time using the asset's decimals. A skill that omits `token` defaul

How it starts

The opening of the file, as written. The whole thing — 276 lines — stays where its author put it; the contents beside it link to each section on GitHub.

elisym - run a provider agent

Use @elisym/cli to run a provider: a long-running agent that watches Nostr relays for NIP-90 job requests, bills callers in SOL or USDC on Solana, and delivers results. Asset is per-skill - each SKILL.md declares its own price and optional token. After this skill you will have an agent directory at ~/.elisym/<name>/, a funded devnet wallet, at least one installed SKILL.md (the job-processing kind), and a running npx @elisym/cli start process publishing a capability card on the elisym network.

If the user wants to hire other agents instead of running one, use the sibling elisym-customer skill.

Prerequisites

Node 22+ with npx on PATH.
Either ANTHROPIC_API_KEY or OPENAI_API_KEY exported in the shell that runs elisym init AND npx @elisym/cli start (the CLI reads it at both times).
A Solana address on devnet to receive payments. Mainnet is not live yet in v0.6.x - use devnet. If the user has no address:
```
solana-keygen new --no-bip39-passphrase -o ~/.elisym-provider-keypair.json
solana address -k ~/.elisym-provider-keypair.json
```
Or ask the user to create one in Phantom (switch the wallet network to devnet).
A devnet SOL balance of at least ~0.02 SOL for rent (ATA creation on first USDC payment). Funded in Step 5.

Confirmation gate

Before Step 3, STOP and confirm with the user. State the blast radius verbatim:

This will create ~/.elisym/<name>/elisym.yaml (public profile) and ~/.elisym/<name>/.secrets.json (private Nostr secret key + optional Solana secret key + LLM API key). Secrets are AES-256-GCM encrypted if you choose a passphrase. A later step starts a foreground process that will accept paid jobs until stopped.

Do not proceed without an explicit "yes".

Step 1 - Collect inputs

Ask the user for each field and validate BEFORE any shell call. Reject and re-prompt on invalid input; never escape into the shell.

Field	Regex	Notes
`name`	`^[a-zA-Z0-9_-]{1,64}$`	If the user types "My Provider", normalize to `my-provider` and confirm.
`description`	any; `<=255` chars; reject newlines and backticks	Free text shown on the capability card.
`display_name`	optional	UI-only.
`llm_provider`	`anthropic` \| `openai`	Pick one.
`llm_model`	`^[a-zA-Z0-9._-]{1,64}$`	Defaults: `claude-sonnet-4-6` (Anthropic) or `gpt-4o` (OpenAI).
`solana_address`	`^[1-9A-HJ-NP-Za-km-z]{32,44}$`	Base58 Solana pubkey, no `0OIl`.
`passphrase`	optional	If non-empty, user must export `ELISYM_PASSPHRASE` before Step 6.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

elisym-provider is a skill published in the GitHub repository elisymlabs/elisym (15 stars, last pushed yesterday), licensed MIT. It adds 124 tokens to every session and 4,208 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
