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.

Ids are yours: accounts acc_..., profiles prf_..., posts pst_...; every other object id is checked against your accounts before the call. Remove a custom field value from a contact. The field definition is not affected. A request reference price is not currently available; use a request quote where supported.

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. ## OpenAPI ````yaml reference-contracts/aisa-social.json DELETE /apis/v1/social/contacts/{contactId}/fields/{slug} openapi: 3.1.0 info: description: '' title: AIsa Social 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: [] x-aisa-document: facts_hash: 99acb5bddbedc8d3352e7c4fef86c3e6d8852c14772bcd18dbcf415237a642bd generator_version: '3' protocol_version: '1' schema_version: '1' composer_version: '27' response_pending: [] document_hash: sha256:7f9742cb1ea233c648dcb290fdfbf24e53a27dcf900ec1386f83a8ef2e6b1bf9 x-aisa-plans: builder: 1 display_plan: payg payg: 1 similarweb_payg: 1 team: 1 version: e70a0959cd1b93b84ae16dffd7a538273ddb9c1d46277b82823c37ff1b6bc0fb x-aisa-provider: aisa-social x-aisa-catalogs: aisa-social: title: AIsa Social description: '' x-aisa-document: facts_hash: 99acb5bddbedc8d3352e7c4fef86c3e6d8852c14772bcd18dbcf415237a642bd 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/social/contacts/{contactId}/fields/{slug}: delete: summary: Clear custom field value description: >- Custom Fields.
