Scored across 7 tools
Most tools target a clearly distinct concern: chat vs embed are different inference modes, quote is explicitly a no-pay price preview, list_models is catalog discovery, receipt is post-payment proof, and key is account/balance state. The only soft overlaps are quote vs chat pricing and session vs receipt (both return shareable/verifiable artifacts), plus `session` bundles four CRUD operations under one name.
All names are lowercase snake-ish single tokens, but the conventions are mixed: bare verbs (chat, embed, quote) sit alongside bare nouns (key, receipt, session) and one verb_noun (list_models). Readable, but there is no predictable pattern an agent can rely on to infer new tool names.
Seven tools is well-scoped for a paid LLM gateway: inference, embeddings, pricing, catalog, account state, receipts, and sessions each cover a real need. No obvious filler or redundant tools.
The surface covers the full pay-per-call lifecycle: discover models, quote, execute (chat/embed), inspect spend, and verify receipts with Merkle proofs, plus multi-turn sessions. Minor gaps exist — wallet-mode balance/spend is only partly addressed via `key` (key mode) and `session` listing, and there is no explicit history/transaction listing tool.
Available Tools
7 toolschatBDestructiveInspect

Inputs: model (required), prompt, system, session, +3 more. Returns: text, batch, level, model, +12 more
embedCDestructiveInspect
Compute embeddings on Phase Router (paid from the Phase API key or the wallet).
Inputs: input (required), model (required). Returns: payment, vectors, price_usd
keyARead-onlyInspect
Balance, daily cap and spend of the Phase API key this server pays with (key mode).
Returns: key
list_modelsARead-onlyInspect
List models of Phase Router with prices (USD per 1M tokens, fee per call) and layer (flagship | open | class | free).
Inputs: layer. Returns: models, wallet, gateway
quoteBRead-onlyInspect
Get the price ceiling for a chat request without paying (the gateway's 402 quote).
Inputs: model (required), prompt, system, session, +3 more. Returns: free, model, network, ceiling_usd, +8 more
receiptARead-onlyInspect
Fetch the public receipt of a paid request by task id (model, provider, tokens, price, settlement tx, request/response hashes, signatures) and its Merkle proof once the weekly epoch is closed.
Inputs: task_id (required). Returns: url, proof, receipt, epoch_state
sessionADestructiveInspect
Saved chat sessions on Phase Router: create one (returns an id and a shareable /s/ link), read its thread, list the wallet's sessions (wallet mode only: signed with the wallet key, no transaction), or delete one.
