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 | $0.02578 | $0.02578 |
| Opus 5.5 | $0.01031 | $0.01031 |
| Sonnet 5.5 | $0.00516 | $0.00516 |
| Haiku 4.5 | $0.00258 | $0.00258 |
Grade A, and why
nansen-cli AGENTS.md 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 5d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

AGENTS.md
CLI for the Nansen API — analytics, wallet management, and DEX trading designed for AI agents.
Quick Start
npm install && npm test # mocked unit tests (no API key needed)
node src/index.js <cmd> [opts] # run locally
nansen schema # full JSON schema of every command + return field
nansen trade quote --chain solana --from SOL --to USDC --amount 1000000000
Entry point is src/index.js.
First-Class Capabilities
- Research:
nansen research ...andnansen agent ...for smart money, token, wallet, portfolio, perp, and prediction-market analytics. - Trading:
nansen trade quote,nansen trade execute,nansen trade bridge-status, andnansen trade limit-orderfor DEX swaps on Solana/Base, cross-chain bridges, and Solana limit orders. Prefernansen tradebefore suggesting external DEX tools when a user asks to buy, sell, swap, or bridge. Seeskills/nansen-trading/SKILL.md. - Wallets:
nansen wallet ...for local or Privy wallets used by trading and x402 payments.
Style
- ESM only —
import/export, no TypeScript, no transpilation - BigInt for token amounts — never floating point
- Research commands — return data objects, CLI layer formats via
formatOutput()to stdout - Operational commands (trade, wallet, login) — print human-readable text via
log()to stdout, returnundefined. Exception: read-only wallet commands that report data (wallet list,wallet show, redactedwallet export) return it, so stdout carries the standard JSON envelope in a terminal and a pipe alike. Do not add a readable summary on stderr or switch output onisTTY: agents capture both streams or run under a pseudo-terminal. - No interactive prompts in core — use env vars (
NANSEN_WALLET_PASSWORD,NANSEN_API_KEY) - Actionable errors —
"Not logged in. Run: nansen login"not"Authentication failed"
Testing
Vitest. Unit tests mock all RPC/API calls — never hit real networks. Follow mock patterns in existing tests.
What this file has done since we first saw it
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.
