cross_lens_verify

A2 — the cross-lens join. Fuse TunnelMind's two lenses (Scry attacker intelligence + Sigil supply graph) into ONE verdict on a single node key. This is the moat: no siloed competitor owns both halves …

sigil_verify_supply_path

The core pre-bid check. Verify the trustworthiness of one programmatic ad supply path and get back a composite trust verdict plus a signed proof token. Sigil composes ads.txt authorization, datacenter…

sigil_verify_ads_txt

Check whether an exchange/SSP is authorized to sell a publisher's inventory, per the publisher's ads.txt file. Fast cached lookup against Sigil's daily crawl of the top ~10k publisher domains. Use th…

sigil_verify_ip_type

Classify an IPv4 address as datacenter, residential, mobile, or unknown. Detects datacenter traffic posing as real user devices. Stateless — the IP is never logged or stored. Use this tool when: - Yo…

sigil_verify_app_bundle

Verify that a mobile/CTV app bundle ID actually exists in its app store and, optionally, that the listed developer matches. Detects bundle-ID spoofing in bid requests. Use this tool when: - A bid req…

sigil_verify_supply_chain

Verify a full OpenRTB SupplyChain (schain) object — every node, end to end. Per node Sigil checks the seller against the exchange sellers.json and the origin ads.txt, then returns a per-node and aggre…

traverse_supply_chain

Walk the supply graph for a publisher domain and get back the ITEMIZED sell paths — distinct from sigil_verify_supply_chain (which verifies a schain you BRING) and from the dark-pool-risk signal (whic…

sigil_score_entity

Get the pre-computed trust score for one supply-chain entity (a publisher or an SSP). Scores are recomputed daily from ads.txt health, supply-chain directness, reach, and stability — deterministic, no…

sigil_score_batch

Pre-computed trust scores for up to 200 entities in one call — built for an agent evaluating many supply sources during campaign setup. Use this tool when: - You have a list of publishers/SSPs to gra…

sigil_atap_register_ait

Register an ATAP v0.1 Agent Identity Token for a media-buying agent. Sigil validates the capabilities + constraints against the `sigil:media_buyer:v1` profile, signs the AIT as the witness, and return…

sigil_atap_witness

Witness one agent-reported bid or budget event into an AIT's hash-chained attestation log. Sigil validates the payload (rejecting any PII), classifies the evidence tier — `anchored` if a bid cites a v…

sigil_generate_receipt

Generate the ATAP v0.1 compliance Receipt for an AIT — the portable, signed artifact a media buyer hands its principal. The receipt grades every event witnessed / anchored / asserted and is verifiable…
