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.

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. * **Declared unit rate (USD):** 1e-06 * **Billing unit:** provider\_credit * **Cost contract:** response\_units * **Published reference multiplier:** 1.0 * **Declared maximum count/units:** 10000000 * **Settlement evidence source:** response\_body ## OpenAPI ````yaml reference-contracts/twelvedata.json POST /apis/v1/twelvedata/get-earliest-timestamp openapi: 3.1.0 info: description: '' title: Twelve Data 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/twelvedata/batch-get-quotes - /apis/v1/twelvedata/commodities-list - /apis/v1/twelvedata/countries-list - /apis/v1/twelvedata/cryptocurrencies - /apis/v1/twelvedata/cryptocurrency-exchanges-list-get - /apis/v1/twelvedata/currency-conversion - /apis/v1/twelvedata/etfs-directory - /apis/v1/twelvedata/etfs-family - /apis/v1/twelvedata/etfs-type - /apis/v1/twelvedata/exchanges - /apis/v1/twelvedata/forex-pairs - /apis/v1/twelvedata/get-earliest-timestamp - /apis/v1/twelvedata/get-funds - /apis/v1/twelvedata/get-last-change - /apis/v1/twelvedata/get-market-state - /apis/v1/twelvedata/get-price - /apis/v1/twelvedata/get-technical-indicators-list - /apis/v1/twelvedata/mutual-funds-family - /apis/v1/twelvedata/mutual-funds-list - /apis/v1/twelvedata/quote - /apis/v1/twelvedata/stocks-list - /apis/v1/twelvedata/symbol-search - /apis/v1/twelvedata/time-series x-aisa-document: facts_hash: be86868d55452e2d3238a78a01e84ee4ea754154da2627dd8e94fd2d5f19c061 generator_version: '3' protocol_version: '1' schema_version: '1' composer_version: '28' response_pending: - operation_id: twelvedata.batch-get-quotes path: /apis/v1/twelvedata/batch-get-quotes method: POST statuses: - '200' reason: public success response has no authoritative payload declaration - operation_id: twelvedata.currency-conversion path: /apis/v1/twelvedata/currency-conversion method: POST statuses: - '200' reason: public success response has no authoritative payload declaration - operation_id: twelvedata.get-price path: /apis/v1/twelvedata/get-price method: POST statuses: - '200' reason: public success response has no authoritative payload declaration - operation_id: twelvedata.quote path: /apis/v1/twelvedata/quote method: POST statuses: - '200' reason: public success response has no authoritative payload declaration - operation_id: twelvedata.stocks-list path: /apis/v1/twelvedata/stocks-list method: POST statuses: - '200' reason: public success response has no authoritative payload declaration - operation_id: twelvedata.symbol-search path: /apis/v1/twelvedata/symbol-search method: POST statuses: - '200' reason: public success response has no authoritative payload declaration - operation_id: twelvedata.time-series path: /apis/v1/twelvedata/time-series method: POST statuses: - '200' reason: public success response has no authoritative payload declaration document_hash: sha256:db5de53df565d48b0eee1a2c8d16d01bbd767993e4ef793c5447395f37fb4e59 x-aisa-plans: builder: 1 display_plan: payg payg: 1 similarweb_payg: 1 team: 1 version: e70a0959cd1b93b84ae16dffd7a538273ddb9c1d46277b82823c37ff1b6bc0fb x-aisa-provider: twelvedata x-aisa-catalogs: twelvedata: title: Twelve Data description: '' x-aisa-document: facts_hash: be86868d55452e2d3238a78a01e84ee4ea754154da2627dd8e94fd2d5f19c061 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/twelvedata/get-earliest-timestamp: post: tags: - Twelve Data summary: Get Earliest Timestamp description: >- A request reference price is not currently available; use a request quote where supported.
