Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

chat_completions

Send a chat completion request to any supported model. Free models are served without payment; the first calls to a PAID model are also free per client (free trials), after which x402 payment (Solana USDC) is required — an unpaid call returns 402 with the exact price; retry with _meta["x402/payment"]. Responses are non-streaming. Pass either mode (auto/eco/premium) or model (explicit id) — one of the two is required; model wins if both are sent. Use this tool to generate text; inspect models and prices first with the free list_models tool. Start with a FREE model (no payment at all) and keep max_tokens >= 200 — a thinking model spends part of that budget on reasoning, so a smaller limit can return an empty answer.

messagesarray, required

Chat messages (text content only). An assistant turn that calls a tool may carry content: null with tool_calls.

modestring

Smart routing profile (auto/eco/premium).

modelstring

Explicit model id (see list_models / /v1/models). Mutually exclusive with mode.

toolsarray

OpenAI-style tool schemas the model may call. Forwarded unchanged; they count as input tokens for the price (§4.2/§5.3).

max_tokensinteger

Max output tokens (billed upfront, §4.2). MCP calls are non-stream: cap per config. Use >= 200 — reasoning models share this budget with their thinking and a smaller limit can return an empty answer.

tool_choicestring

OpenAI tool_choice: 'auto', 'none', 'required', or {type: function, function: {name}}.

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

get_price_estimate

Estimate the USDC cost of a chat completion request before paying — free, no payment, no authentication required. Read-only: no state changes and no external calls; the estimate is computed locally from server pricing config, so repeated calls with identical inputs return identical results (idempotent). Use this tool to check the exact price for a given model/mode, messages, and max_tokens before calling the paid chat_completions tool. Provide either mode (auto/eco/premium routing) or model (explicit id, mutually exclusive with mode); one of the two is required — if both are sent, model wins. mode values: auto = cheapest model fitting the context, eco = cheapest available, premium = best model.

read-only

Argument	Type	Description
mode	string	Smart routing profile (auto/eco/premium).
model	string	Explicit model id (see list_models / /v1/models). Mutually exclusive with mode.
messages*	array	Chat messages (text content only).
max_tokens	integer	Max output tokens to estimate (billed upfront, §4.2).

list_models

List available models and their prices — free, no payment, no authentication required. Read-only: no state changes; data is served from the server's local config, so repeated calls return identical results (idempotent). Accepts no parameters: the input schema is an empty object, and any arguments passed are ignored. Calling it without arguments returns the complete catalog with per-token prices; there is no filtering, pagination, or configuration. Use this tool to inspect models and prices before calling the paid chat_completions tool. Same data as GET /v1/models (§5.2). Do not use it to generate text (use chat_completions) or to estimate a specific request's cost (use get_price_estimate).

read-only

No arguments.
