Official Source Evidence

Isolated Compute, Agent Procurement, Evidence, Source Watch, and GTM Signals

One-call isolated Python execution, brokered machine-service procurement, long-running monitoring jobs, and pay-per-call official-source signals and evidence for autonomous agents. No account, API key, or sales call.

The Source Watch demand hypothesis, attribution rules, and stop/scale gates are pre-registered in SOURCE_WATCH_EXPERIMENT.md. The first independent buyer's on-chain cohort, interpretation, and resulting actions are recorded in INDEPENDENT_BUYER_ANALYSIS.md.

Agent-Payable Products

All routes use x402 v2 on Base mainnet. An x402-compatible client receives a standard HTTP 402 challenge, pays USDC, retries automatically, and receives the JSON result. Browser clients can read the payment headers through CORS. During the v1-to-v2 transition, a v2 payload sent under the legacy X-Payment header is promoted to Payment-Signature. The production service has a hard $10.00 accepted-revenue cap per UTC day.

The procurement experiment tests a brokered action, not another raw-data wrapper. A free quote at POST /v1/procure/company-profile/quote exposes the fixed customer price, supplier plan, maximum supplier cost, and partial-result policy before payment. The hypothesis and stop/scale gates are pre-registered in PROCUREMENT_EXPERIMENT.md.

The isolated Python experiment compresses a three-payment sandbox lifecycle into one buyer call. A free quote exposes the fixed $0.03 customer price and maximum $0.015 supplier cost before payment. The bounded hypothesis and gates are in PYTHON_RUN_EXPERIMENT.md.

Source Watch is a long-running job rather than a lookup. It accepts only public HTTPS sources, does not follow redirects, caps each response at 1 MB, stores normalized text rather than raw pages, and expires automatically after 30 days. The paid response returns a bearer token for private status polling and, when requested, a separate HMAC secret for verifying change webhooks.

Monitoring tools may send an empty or {} unauthenticated POST to any paid route. The service treats that as the published example request and returns the normal HTTP 402 challenge without fetching upstream data or charging. The same substitution is preserved on the paid retry so a catalogue purchase can finish. Malformed or other schema-invalid requests are still rejected before payment.

Discover and Inspect

The stateless Remote MCP at https://evidence.regulavita.com/mcp/ exposes free status, quotes, and capability requests. get_example_payment creates a live x402 challenge from a known-valid published example without moving funds; this lets generic catalog agents reach the payment decision without inventing test inputs. Custom-input tools remain strict and return a machine-readable recovery path when validation fails.

An unpaid valid request demonstrates the machine-readable payment challenge:

curl -i -X POST \

https://evidence.regulavita.com/v1/gtm/form-d-funding-leads \ -H 'Content-Type: application/json' \ -d '{"since":"2026-08-03T00:00:00Z","states":["CA","NY"],"minimum_amount_sold_usd":"1000000","limit":10}'

Decision And Evidence Layers

The two $0.01 routes return compact, unsigned decisions for frequent agent workflows. The Form D GTM feed and premium evidence routes add:

• Official publisher and source-version metadata.
• Canonical request, source-bundle, component, and result SHA-256 hashes.
• An Ed25519-signed evidence receipt.
• Explicit data freshness and parser version.
• Paid-result replay bound to the original payment proof.

The OFAC route is exact-match evidence only. It is not fuzzy screening, ownership/control analysis, sanctions clearance, transaction authorization, or legal advice. The SEC route returns factual filing records and deterministic deltas, never materiality opinions, valuation, investment advice, or execution instructions.

The Form D route is a factual sales trigger. Form D is an issuer-filed notice of an exempt offering; its total offering amount is not proof of capital raised. The API exposes the separately reported amount sold and preserves official SEC links so consuming agents can state that distinction accurately.

Operator Documentation

The implementation, source controls, payment flow, deployment configuration, operating limits, and experiment gates are documented in autonomous_data_api/README.md.

This remains a capped demand experiment. Owner-funded calls prove technical settlement and discovery, not independent demand, revenue quality, or a validated business.
