What is Signalis?

What you get

• Master Intelligence — a 4-hourly cross-domain synthesis: executive summary, full markdown analysis, cross-domain insights, detected narratives, discrete signals, and an overall sentiment read. Free to poll and read via /v1/intelligence/index, /brief, and /latest.
• Historical master digests — /v1/intelligence/history returns past digests over a 1–168 hour lookback, each with its sourcesUsed and createdAt provenance.
• Pulse narratives — active AI-business narratives with lifecycle stage and momentum (/v1/pulse/narratives), per-narrative detail with content items and source attribution (/v1/pulse/narratives/{id}), historical narrative digests (/v1/pulse/digests), and the raw recent content items behind them (/v1/pulse/content/recent).

Prices come straight from the service manifest. See the full pricing on the homepage.

How agents pay

Call a paid route with no payment and Signalis replies with an HTTP 402 — the x402 V2 PaymentRequirements ride in a base64 header and the JSON body mirrors the price and accepts[]. Your client signs an EIP-3009 exact-scheme USDC authorization on Base for the requested amount and retries the same request with the payment header. Compute-first / settle-after means you are never charged for an error. Start with a free read:

Alternatives

The usual way to build situational awareness is to wire up raw news APIs and RSS feeds yourself, then run your own summarization on top. That gives you full control over sources and cadence, but you own the aggregation, deduplication, cross-source synthesis, and narrative tracking — and you pay for whatever infrastructure and subscriptions that requires.

Signalis trades that control for a finished product: one synthesized global digest refreshed every 4 hours plus tracked AI-business narratives, delivered as a single structured response you pay for by the call. The tradeoff is that you consume Signalis’s 20-source roster and 4-hour cadence rather than curating your own. Both are reasonable — raw APIs when you need bespoke coverage, Signalis when you want the synthesis done and priced per call.

FAQ

What is Signalis?

Signalis is a pay-per-call global-intelligence API for AI agents. It runs two surfaces: Master Intelligence — a cross-source synthesis produced every 4 hours from a 20-source roster into a structured digest (executive summary, full analysis, cross-domain insights, narratives, signals, sentiment) — and Pulse, an AI-business narrative feed with lifecycle stage, momentum, source attribution, and the raw content behind each narrative.

How do agents pay for Signalis?

Paid routes settle per call via x402 micropayments in USDC on Base Mainnet. Call a paid route with no payment to receive an HTTP 402 challenge, sign an EIP-3009 exact-scheme USDC authorization, then retry with the payment header. Stock x402 clients (@x402/fetch, @x402/axios, python x402) do this automatically. There are no accounts and no API keys.

Can I try it before paying?

Yes. The Master Intelligence feeds are free to poll and read: GET /v1/intelligence/index (poll for new digests), /v1/intelligence/brief (title, executive summary, sentiment), and /v1/intelligence/latest (the full current digest). GET /v1/intelligence/sample returns a recent, explicitly-labelled sample so you can learn the response shape before paying.

How fresh is the data?

Master Intelligence digests are produced on a 4-hour cadence, and /v1/intelligence/index advertises the nextExpected time so agents can detect new digests. Each digest carries createdAt provenance and reports the exact sources it used that cycle in its sourcesUsed field. Pulse narratives are recomputed by the Pulse pipeline on a similar cadence.
