API and tools
Hedge Layer is in public beta and still being developed and tested. The HTTP API, MCP tools and Hedge Layer Agent cloud endpoints are part of this beta. Features and availability may change. Results may be incomplete or incorrect; check the original sources.
Use integrations for testing and evaluation. Tool schemas, limits and behaviour may change during the beta; check this reference and the live tool catalog when updating your client.
MCP and HTTP are two transports over the same tool registry. They share names, schemas, scopes, validation, and provider calls.
Financial datasets
Call list_financial_datasets to search installed datasets by keyword and discover access requirements, limitations, tool names, and examples. The same catalog is listed below. Public upstream sources require no vendor subscription; authenticated Hedge Layer access is still required.

}SEC EDGAR filings and company facts
Ticker-to-CIK lookup, full filing history, filing text by Item (10-K, 10-Q, 8-K and exhibits) and reported XBRL financial facts, with CIK identity, filing dates, units and source links.
Provider: U.S. Securities and Exchange Commission. Upstream cost: free. Updates: Updated as filings are disseminated by EDGAR.
Trust: Primary source, published by U.S. Securities and Exchange Commission. Public U.S. government EDGAR data, accessed under the SEC fair-access policy. Reviewed 2026-09-28; next review due 2027-09-28.

- get_sec_company_filings covers the recent submissions block only; get_sec_filing_history reads archives, at most five pages per call.
- Filing text is converted from HTML heuristically: Item detection can miss unusual layouts and tables are flattened. Earnings-call transcripts are not included; 8-K earnings releases (item 2.02, EX-99.1) are.
- Facts retain restatements and different reporting periods; they are not normalized statements.
- Subject to SEC fair-access policy and provider rate limits.

{"arguments":{"query":"bitcoin","venues":["polymarket","hyperliquid"],"limit":5}}Successful invocations return an MCP CallToolResult containing content and structuredContent. HTTP errors may return { "error": "..." }. Check the HTTP status and isError.

Request limits
Financial tool request bodies over HTTP and MCP are limited to 64 KiB. Evidence search allows ten calls per user in a 60-second window. HTTP rate-limit responses include Retry-After; MCP tool errors include retry_after_seconds.
MCP
Connect using Streamable HTTP at https://hedgelayer.ai/mcp. Call tools/list to discover the same catalog, then tools/call with the tool name and arguments.
Authorization
The MCP endpoint implements the MCP authorization specification with OAuth 2.1. An unauthenticated request returns 401 with WWW-Authenticate: Bearer resource_metadata="…/.well-known/oauth-protected-resource/mcp". Hedge Layer is the authorization server:
| Endpoint | Purpose |
|---|---|
/.well-known/oauth-protected-resource/mcp | Protected resource metadata (RFC 9728) |
/.well-known/oauth-authorization-server | Authorization server metadata (RFC 8414) |
/oauth/authorize | Sign-in and consent; authorization code with PKCE S256 |
/api/oauth/token | authorization_code and rotating refresh_token grants |
/api/oauth/register | Dynamic client registration (RFC 7591), public clients only |
/api/oauth/revoke | Token revocation (RFC 7009) |
Clients may instead use an HTTPS client ID metadata document as their client_id. Send resource=https://hedgelayer.ai/mcp (RFC 8707). The only scope is read. Access tokens last one hour and are accepted only by /mcp; refresh tokens rotate on every use, and reusing one revokes the connection. Personal tokens keep working on every endpoint.
Hedge Layer Agent cloud agent
Current Hedge Layer Agent clients use POST /api/agent/v1/turns with a read-scoped personal token. The shared cloud runtime owns the agent loop, research tools, and workspace. The API derives session identity from the authenticated account and thread; clients cannot choose another user's session. Runs stream Hedge Layer Agent events through a final [DONE] marker.
To ask by voice, send the recording to POST /api/agent/v1/transcriptions with the same token and an audio Content-Type (audio/ogg, audio/webm, audio/mpeg, audio/mp4, audio/aac, audio/wav or audio/flac). The body is the raw recording, at most 4 MB. It returns {"text": "..."}; show it to the user, then send it as the turn prompt. Transcription shares the cloud agent's ten-requests-per-minute limit and is never retried.
Desktop and WhatsApp use this same agent. Each client maintains its own threads. The agent only uses read-only tools, so there are no approval requests.
For older clients, POST /api/agent/v1/chat/completions remains available as a hosted-inference gateway. That legacy endpoint allows ten requests per user per 60 seconds, with a 1 MB request body limit and at most 16,384 output tokens per request. A 429 response includes Retry-After.
Data
Read tools return observations with exact decimals, units, source metadata, and retrieval times. Missing observations remain missing. Polymarket collateral amounts use venue_collateral, prices use collateral_per_share, and order sizes use shares. Web evidence is untrusted external content.
Hedge Layer does not submit, cancel, or look up venue orders.
