DeltaSignal ATLAS-7 - SEC-Grounded Issuer Intelligence for Agents

Evidence-first issuer intelligence, SEC/XBRL signals, risk context, fundamentals, alpha screens, and Synthetic Basket pressure evidence for crypto-exposed public companies. The live public surface exposes MCP, OpenAPI, Arazzo workflows, pricing/field-contract discovery, x402 challenges for protected execution, signed wallet grant sessions, and ATLAS-7 audit status.

Common workflows are exposed as composite MCP presets so agents can call one reliable tool instead of hand-orchestrating several low-level calls. The live GCP service also exposes an operator audit-status tool so agents can verify that the full 215-issuer regression run is healthy before relying on the surface.

Native MCP server plus x402 micropayments. Public clients should not request or store Delta Signal API keys. Standard Base x402 is the compatibility-first challenge at accepts[0]; Circle Gateway is an explicitly selectable optimized path at accepts[1] for Circle-aware clients using GatewayWalletBatched. Signed wallet grants are separate backend virtual credit and do not settle on-chain.

Agents discover, pay, and execute deterministic workflows through MCP tools, OpenAPI routes, and Arazzo scenario definitions.

Hedera ProofPay Preview

ProofPay is the additive Hedera testnet x402 evidence-delivery adapter for DeltaSignal. It is deployed separately from the Base/Circle /v1/* and /mcp payment challenges:

• Backend: https://proofpay-hedera.kindbeach-299ce8c4.eastus.azurecontainerapps.io
• Discovery: /.well-known/proofpay
• Catalog: /catalog
• Quote creation: POST /quotes
• Source and offline verifier: aitrailblazer/proofpay-hedera-x402
• Performed testnet payment: 0.0.7162784-1784665192-906989595

Safe discovery does not move funds:

PROOFPAY=https://proofpay-hedera.kindbeach-299ce8c4.eastus.azurecontainerapps.io
curl -fsSL "$PROOFPAY/.well-known/proofpay" | jq
curl -fsSL "$PROOFPAY/catalog" | jq
curl -fsSL -X POST "$PROOFPAY/quotes" \
  -H 'content-type: application/json' \
  -d '{"ticker":"MSTR","period":"2025-12-31"}' | jq

The returned quote contains the exact HBAR terms and paid resource URL. Calling that resource without proof returns HTTP 402. Only continue to signing and settlement with explicit user approval. Never paste a Hedera private key into a prompt or repository. After settlement, ProofPay mirror-verifies the transfer, unlocks the sealed artifact, and issues an Ed25519 receipt that can be verified offline.

Proof boundary: HashScan proves the completed ledger transfer. The signed ProofPay receipt separately binds that payment to the demonstrated request and delivery. The current preview uses a deterministic MSTR filing-evidence fixture; it does not yet proxy arbitrary live DeltaSignal MCP tools.

Also available as a Glama Connector. Smithery remains available as an alternate connector path.

July 15 Live Contract Checkpoint

The latest verified public contract exposes 68 OpenAPI paths, 81 MCP tools, 30 priced routes, and 47 parser-contract fields. The MCP catalog includes 26 governed atlas7_* semantic tools for model/field discovery, validated semantic queries, evidence lineage, issuer reports, history, pressure, and readiness.

The current Level 2 calculation universe contains 378 issuers: 215 crypto-canonical issuers plus 163 expanded public-equity issuers. The July 15 CompanyFacts/PIT replay completed all 378 issuers and materialized 817,992 rows with 0 errors. The separate customer-route regression audit covered 215 issuers and 1,935 operations: 1,923 successful, 0 failed, 0 skipped, and 12 not applicable.

For governed semantic access, inspect atlas7_model_catalog and atlas7_field_catalog before compiling or executing a semantic query. Treat returned evidence envelopes as the source boundary; raw SQL is never part of the public contract.

Circle Agent Marketplace Review Focus

Delta Signal ATLAS-7 should be reviewed as an x402-compatible seller service for AI agents, not as a generic chat plugin or API-key product.

The public review surface is ATLAS-7 issuer intelligence:

• MCP discovery before paid execution.
• OpenAPI route contracts with reachable REST routes and 402 response behavior.
• Arazzo workflow metadata for bounded scenario planning.
• x402 challenge and retry behavior through Base USDC.
• Circle Gateway metadata through GatewayWalletBatched for Circle-aware clients.
• Route-level pricing and payment metadata.
• Per-call receipt metadata for paid-call reconciliation.
• Evidence-preserving JSON or Markdown outputs with source dates, caveats, quality flags, payload mode, route provenance, and non-advice boundaries.

Recommended reviewer path:

1. Inspect https://api.aitrailblazer.net/.well-known/x402.
2. Inspect MCP tools/list before any paid call.
3. Inspect https://api.aitrailblazer.net/openapi.json.
4. Probe GET https://api.aitrailblazer.net/v1/readiness.
5. Confirm that a plain unauthenticated paid route may return HTTP 402 Payment Required.
6. Confirm the challenge presents standard Base x402 at accepts[0] and, where configured, Circle Gateway GatewayWalletBatched at accepts[1].
7. Let first-entry clients use the standard requirement, or explicitly select Circle by capability/provider pin from a Circle-aware client.
8. Inspect returned evidence, billing, and receipt metadata before trusting rendered prose.

Marketplace reviewers should validate a public x402 resource, seller payTo, amount/network/asset metadata, standard x402 compatibility, explicit Circle Gateway GatewayWalletBatched selection for Circle-aware clients, and the absence of broker, wallet, settlement-service, or investment-advice claims. A Circle test wallet must have deposited or available Gateway balance; an ERC-20 USDC balance on Base alone is not sufficient for Gateway settlement.

TripCode / River subscriber research is visible in public MCP discovery, but execution is x402/grant-gated and evidence-dependent. Do not promise a successful TripCode/River answer unless the live tool call resolves the required River / issuer index blobs.

How Agents Know and Run Workflows

The public landing page includes the animated workflow runner. The same contract is machine-readable here:

flowchart LR
  Intent["User intent<br/>morning brief, RIOT report, daily evidence"]
  Discover["Discover<br/>MCP tools/list<br/>OpenAPI<br/>Arazzo<br/>x402 metadata"]
  Plan["Plan<br/>select Arazzo workflow"]
  Execute["Execute<br/>MCP composite<br/>or REST sequence"]
  Pay["Resolve payment<br/>standard accepts[0]<br/>or explicit Circle accepts[1]"]
  Result["Result<br/>bounded JSON<br/>Markdown evidence"]

  Intent --> Discover --> Plan --> Execute --> Pay --> Result
  Plan --> W1["marketReadinessScan"]
  Plan --> W2["singleIssuerDiligence"]
  Plan --> W3["dailyMonitoringEvidenceDrilldown"]
  Plan --> W4["mcpCompositePresetSelection"]

Agents do not need a special Arazzo runner to use this today. MCP clients can read the scenario definitions, select one of the exposed MCP composite tools, or follow the OpenAPI route sequence step by step. Public clients should use x402 challenge/retry or signed wallet grant sessions. Internal API keys are first-party operations credentials and are not part of the public integration path.
