搜索. Describe. Quote. Run.
GET /api/capabilities searches by natural-language query and category. Describe the selected slug before constructing input: its schema is the source of truth for 字段, pricing, 文件 requirements, and execution support.

quote_id. - 运行Send the same input, quote ID, and a unique idempotency key.

创建 a scoped API key from Dashboard → Developers. Send Authorization: Bearer YOUR_SWARME_API_KEY. Never put a key in client-side code, URLs, logs, or a repository.
Scopes
Use only the needed scopes: capabilities:read, capabilities:quote, capabilities:run, uploads:write, artifacts:read, and billing:read.
Spend limits
Each client may have a USD cap. Check GET /api/account/balance before paid work; wallet or spend-limit failures are hard stops.
Idempotency
Use one stable Idempotency-Key per logical quote/run attempt. Replays return the original work; a key cannot safely represent different input. Paid API runs may require it.
Quotes
Quote immediately before execution and pass its quote_id. Surface the price or policy failure 到 the user.
Use short-lived 上传 sessions.
创建 a session for the selected slug, 上传 raw bytes 到 its returned URL with the dedicated token, then supply 上传_id (or 上传_ids) in quote and run input. Validate filename, MIME type, and 大小 against describe. Never reuse or log an 上传 token.
# 创建 a session. Keep its 上传_token private.

# Read 上传_url and 上传_token from the response, then:
curl -X PUT "YOUR_上传_URL" -H "Authorization: Bearer YOUR_上传_TOKEN" \
-H "Content-Type: application/PDF" --data-binary @文档.PDF

The canonical values are supported, requires_worker, 套餐_only, and describe_only. supported executes in the declared mode. requires_worker preserves the worker-required response until that runtime is ready. 套餐_only returns a client 套餐 without server processing. describe_only blocks quote/run. The legacy value runnable is accepted as supported for backward compatibility. Treat missing or unknown values as describe_only and re-describe before execution.
The same safe flow, as tools.
Connect a streamable HTTP client 到 https://swarme.io/zh/mcp. Begin with tools/list; do not assume a cached list.

}Version and deprecate contracts explicitly.
The contract manifest inventories REST, MCP tools, execution and run states, quote/run and 文件 lifecycles, errors, and scopes. The machine-readable changelog classifies changes as additive, behavioral-risk, or breaking. Unknown manifest elements fail compatibility checks conservatively.
运行 php bin/check-contract-compatibility.php --baseline=BASELINE.json --candidate=CANDIDATE.json locally or in CI. Breaking changes fail unless their stable change IDs appear in an explicit local approvals 文件.
Deprecation convention
When deprecation is activated for an element, publish manifest deprecated 元数据 and use standard Deprecation, Sunset, and 链接: <...>; rel=deprecation 标头 plus Swarme-Contract-Version. The configured target is at least 90 days' notice when practical. It is a governance target—not an SLA—and urgent 安全, legal, abuse-prevention, or uncontrollable upstream changes may require less notice. This increment configures and 文档 the convention only; it does not deprecate or 移除 any endpoint.
Use any HTTP client.
These examples use environment variables and placeholders only. They contain no credentials. The source distribution also includes copyable, dependency-free examples/rest-agent.php 和 examples/mcp-agent.php recipes covering 搜索 through artifacts or cancellation, with an explicit --approve boundary and optional --file=PATH 上传.
Before integration, run php bin/check-agent-contract.php against bundled versioned fixtures. Supplying --base-url=URL is explicit and performs only read-only public discovery checks. These are reusable starter clients—not a generated SDK or a frozen SDK API.
