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.

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. * **Cost contract:** response\_units * **Published reference multiplier:** 1.0 * **Settlement evidence source:** response\_body ## OpenAPI ````yaml reference-contracts/vaquill.json POST /apis/v1/vaquill/us/statutes/section/changes openapi: 3.1.0 info: description: '' title: Vaquill version: '1' x-aisa-capabilities: idempotency: Idempotency-Key max_price: X-AISA-Max-Price-USD quote: header: X-AISA-Cost-Mode value: quote x-aisa-configured-paths: - /apis/v1/vaquill/us/statutes/count - /apis/v1/vaquill/us/statutes/divisions - /apis/v1/vaquill/us/statutes/resolve - /apis/v1/vaquill/us/statutes/search - /apis/v1/vaquill/us/statutes/section - /apis/v1/vaquill/us/statutes/section/body - /apis/v1/vaquill/us/statutes/section/changes - /apis/v1/vaquill/us/statutes/section/cited-by - /apis/v1/vaquill/us/statutes/section/cross-state - /apis/v1/vaquill/us/statutes/section/definitions - /apis/v1/vaquill/us/statutes/section/related - /apis/v1/vaquill/us/statutes/sections x-aisa-document: facts_hash: b4be8345fd8915d3f9d5a6708e594f13679f07b8121981339382557f368523ab generator_version: '3' protocol_version: '1' schema_version: '1' composer_version: '27' response_pending: [] document_hash: sha256:e7fedcc441ae12e2823a00a2cb9dfa38930edf7ea76db49c4d8d477f9b96b5e6 x-aisa-plans: builder: 1 display_plan: payg payg: 1 similarweb_payg: 1 team: 1 version: e70a0959cd1b93b84ae16dffd7a538273ddb9c1d46277b82823c37ff1b6bc0fb x-aisa-provider: vaquill x-aisa-catalogs: vaquill: title: Vaquill description: '' x-aisa-document: facts_hash: b4be8345fd8915d3f9d5a6708e594f13679f07b8121981339382557f368523ab generator_version: '3' protocol_version: '1' schema_version: '1' x-aisa-plans: builder: 1 display_plan: payg payg: 1 similarweb_payg: 1 team: 1 version: e70a0959cd1b93b84ae16dffd7a538273ddb9c1d46277b82823c37ff1b6bc0fb x-aisa-capabilities: idempotency: Idempotency-Key max_price: X-AISA-Max-Price-USD quote: header: X-AISA-Cost-Mode value: quote servers: - url: https://api.aisa.one security: - bearerAuth: [] paths: /apis/v1/vaquill/us/statutes/section/changes: post: tags: - Vaquill summary: Vaquill Get Section Change History description: >- Vaquill Get Section Change History A request reference price is not currently available; use a request quote where supported.
