A tool for finding routes to swap one cryptocurrency for another across decentralised exchanges, including swaps between supported blockchains.

Getting cryptocurrency swap quotes and routing swaps across supported chains. It also supports a 1% referral fee paid to the configured wallet.

It helps compare exchange routes and handle cross-chain swaps instead of checking each exchange manually.

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	$0.00024	$0.01701
Opus 5	$0.00012	$0.00851
Sonnet 5	$0.00005	$0.00340
Haiku 4.5	$0.00002	$0.00170

Measured 11d ago against content hash 22b126cb5b63, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-10, from the pricing page.

Security

Grade A, and why

openocean 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 11d 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.

Makes network callslowCapability

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

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.
