> ## Agent Instructions
> - Base URLs: models `https://api.aisa.one/v1` (Gemini GenerateContent: `https://api.aisa.one/v1beta`); data APIs `https://api.aisa.one/apis/v1`. The `servers` of each operation in https://aisa.one/openapi.yaml is authoritative.
> - Auth: `Authorization: Bearer $AISA_API_KEY`. Never print, log, or commit the key.
> - MCP (preferred for agents): `https://mcp.aisa.one/mcp`, signed in with OAuth, so there is no key to paste.
> - Agent Skill: `npx skills add AIsa-team/agent-skills --skill aisa`. Fallback with the AIsa CLI: `aisa skills install aisa`.
> - Spending: docs, https://aisa.one/models, https://aisa.one/api, `/v1/models`, and MCP `search`, `list_categories`, `get_details`, `batch_quote`, and the `account` operation are free. Quote the exact calls before running them (MCP `batch_quote`, CLI `aisa quote --json`). If the quote reports `auto_execute_eligible: true`, run it unless the user set a tighter limit or asked only for a quote. Otherwise, tell the user in one message the planned calls, the quoted price, and a total USD budget for the task, then wait for approval. Direct HTTP calls follow the stricter rule at https://aisa.one/docs/get-started/cli.md#direct-http-fallback. Do not make paid calls to test availability. Full rule: https://aisa.one/llms.txt

# Reverse-search an image with Google Lens

> Answers arrive in organic. Two valid public-image probes returned HTTP 200 with an empty organic array and credits: 3; an empty match set is therefore a paid, valid answer, not an error.

## Cost and request rules

Usage-based billing; Default request estimate: \$0.003 USD (not a fixed price). Declared unit rate: \$0.000001 USD per provider\_credit. Account-specific pricing and final settlement may differ.

Published reference values are not an account-specific quote or a settled charge. For endpoints supporting X-AISA-Cost-Mode: quote, obtain a free quote for your exact request before execution; reconcile the settled cost with response metadata and Usage Logs. USD amounts use 1,000,000 integer micro-USD per dollar.

* **Default request reference estimate (USD):** 0.003
* **Declared unit rate (USD):** 1e-06
* **Billing unit:** provider\_credit
* **Cost contract:** response\_units
* **Published reference multiplier:** 1.0
* **Settlement evidence source:** response\_header
