Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• audit_entries auth-required 32m ago

  List the immutable audit-archive entries for the caller's API key: every Montgomery evidence report the key generated (text or json), newest first, each with its entry id, generation timestamp, DOT number, scoring date, methodology version and the SHA-256 of the archived report text. Requires a paid CarrierScore API key. Use it to answer "which carriers did we generate evidence for, and when?" and to find the entry id to cite or verify for a given carrier and date. Monitor keys see the last 90 days; Compliance keys see everything ever archived. Args: - dot_number (optional): only entries for this US DOT number - since (optional): YYYY-MM-DD; only entries generated on/after this date (UTC) - limit (optional): 1-500, default 50 Returns JSON: { tier, retention_days, total_entries, matched, count, entries: [{ entry_id, generated_at, dot_number, sha256, format_requested, scored_as_of, score_version }] }. Errors: 403 without a paid key; 400 if since is malformed.

• carrier_score unknown never probed

  Get the CarrierScore risk indices for a carrier by US DOT number: two first-class, separately validated indices (0-100, HIGHER = RISKIER), each with a full component breakdown. This is the core "is this carrier safe to book?" signal for AI booking agents. Served methodology v0.5 returns TWO indices, both population-relative and built from point-in-time public FMCSA data: - inspection_risk — inspection / compliance risk: violations and out-of-service rates per roadside inspection (24-month chronic, 6-month acute). Historically validated against the carrier's future out-of-service rate (validation block on the index). - crash_risk — crash risk: reportable crashes, fatal/injury crashes and tow-away crashes per roadside inspection (24 months). Historically validated against future reportable crashes (validation block on the index). Present BOTH indices; do not collapse them into one number. Hard flags (active out-of-service order, no active insurance filing, high-confidence reincarnated-carrier link) add explicit surcharges — a carrier with any flag deserves extra scrutiny regardless of index values. Returns JSON: { dot_number, legal_name, inspection_risk: { label, description, score, base, surcharge, percentile_basis, band, band_note, data_sufficiency, components: { <name>: { label, value, percentile, weight } }, validation: { auc_holdout, label, holdout_origins, post_selection_origin, source, text } }, crash_risk: { ...same shape... }, legacy_composite: { score, base_score, surcharge, rule, rule_text, validated: false, note }, carrier_score (backward-compatible: == legacy_composite.score under v0.5), base_score, surcharge, score_version ("0.5"), methodology_note, components (flat, backward-compatible), flags: string[], data_sufficiency (0-1, share of the components resting on observed vs neutral-imputed data), scored_as_of, disclaimer }. Older opt-in methodologies keep their shapes: v0 (six components), v0.3 (sub_indices), v0.4 (indices + composite). Interpreting for booking decisions: treat the indices as documented decision-support evidence, not an approve/deny verdict. legacy_composite / carrier_score is NOT validated and is kept only so older integrations keep working — never present it as the carrier's risk score. Low data_sufficiency means limited inspection history — common for new carriers, itself a risk signal. Always relay each index's validation text and the disclaimer when presenting the result. Errors: 404 if the DOT is not in the scored population; 503 if scores have not been computed yet.

• carrier_lookup unknown never probed

  Look up an FMCSA-registered motor carrier's identity by US DOT number: legal name, DBA, operating status, FMCSA safety rating, fleet size (power units, drivers), physical address, and registration dates. Use this first when a booking/dispatch agent needs to confirm WHO a carrier is — that a DOT number is real, active, and matches the company name on a rate confirmation. It does not return risk indices (use carrier_score for those). Returns JSON: { dot_number, legal_name, dba_name, status_code, safety_rating, power_units, total_drivers, phy_street, phy_city, phy_state, phy_zip, add_date, mcs150_date }. Errors: 404 if the DOT is not in the FMCSA census (likely a typo or a fraudulent/never-registered carrier — treat as a red flag for booking).

• montgomery_file unknown never probed

  Generate a timestamped Montgomery file — a carrier-selection evidence report — for a carrier by US DOT number. Since Montgomery v. Caribe Transport II (SCOTUS, May 2026), freight brokers are exposed to state-law negligent-selection claims and need documented, timestamped, safety-data-based carrier selection. This report is that artifact: the two risk indices (inspection / compliance risk and crash risk, each with its components, percentiles, activity-band context and its own historical-validation line), the legacy composite (labelled backward-compatibility only), hard flags, FMCSA safety rating, and the methodology disclaimer, dated as of the scoring run. A booking agent should generate and retain this file at the moment a carrier is selected for a load. Args: - dot_number: US DOT number, digits only - format: "text" (default; the filing-ready plain-text report, available on the free tier) or "json" (structured fields; requires an API key on the monitor or compliance tier) Returns: format="text" gives the plain-text report (structured field report_text); format="json" gives structured fields { report, generated, dot_number, legal_name, dba_name, safety_rating, status_code, power_units, inspection_risk, crash_risk, legacy_composite (v0.5), carrier_score (backward-compatible), components, flags, data_sufficiency, score_version, scored_as_of, disclaimer } (v0.4 parquets return indices + composite instead). Every report embeds the disclaimer verbatim — keep it when storing or quoting the report. Audit archive (paid tiers): every report generated with an API key is stored immutably server-side and the result carries audit_entry_id + sha256 (SHA-256 of the plain-text report). Quote both when citing the report; later, verify_evidence(entry_id) proves the archived copy is unchanged and audit_entries lists what was generated. Monitor keys can retrieve the last 90 days (2,000 reports/month); Compliance keys have unlimited retention and reports. Errors: 403 if format=json without an API key; 404 unknown DOT; 429 if a Monitor key has used its 2,000 reports this month (upgrade hint in the message); 503 if scores are not computed yet.

• monitor_carriers unknown never probed

  Batch risk check for a list of carriers by US DOT number (max 100 per call): score summary and hard flags for each. Use when an agent is screening multiple candidate carriers for a load, or re-checking a broker's active carrier roster ("did any of my carriers pick up an out-of-service order or drop insurance?"). For a full breakdown of any single carrier that looks risky here, follow up with carrier_score or montgomery_file. Args: - dot_numbers: array of DOT number strings, 1-100 entries Returns JSON: { scored_as_of, requested, found, carriers: [{ dot_number, legal_name, inspection_risk (0-100 inspection / compliance risk index, higher = riskier), crash_risk (0-100 crash risk index), carrier_score (legacy composite under v0.5 — backward compatibility only; use the two indices), data_sufficiency, flags: string[] }], not_found: string[], disclaimer }. DOTs in not_found are absent from the scored population — verify them with carrier_lookup; an unknown DOT on your roster is itself a red flag. Errors: 400 if the list is empty or exceeds 100 (split into batches); 503 if scores are not computed yet.

• save_carrier_list unknown never probed

  Save a named list of carriers (by US DOT number) for continuous monitoring. Requires a paid CarrierScore API key (Monitor or Compliance tier) — connect with your key via OAuth (or set CARRIERSCORE_API_KEY on a self-hosted server); the free tier gets a 403 with an upgrade link. Once saved, CarrierScore diffs every carrier on the list against the previous day's scoring run after each daily run and records alerts: new out-of-service order (critical), operating authority lost (critical), insurance filing lapsed (high), operating status leaving Active (high), risk score up 10+ points (medium), high-confidence reincarnated-carrier link appearing (medium). Alerts are always retrievable with list_alerts; optionally they are also pushed to a webhook (JSON POST, HMAC-signed via the X-CarrierScore-Signature header with the per-key secret from GET /v1/lists) and/or summarized in one daily digest email. Use this when a broker asks to "watch" or "keep an eye on" their carrier roster. Caps: 500 DOTs total across all lists on the Monitor tier, 5000 on Compliance; up to 50 lists per key. Saving the same DOT twice in one list is deduped. Args: - name: short label for the list (1-100 chars) - dot_numbers: array of DOT number strings (1-8 digits each) - webhook_url (optional): https URL to POST new alerts to - email (optional): address for the daily digest Returns JSON: { list_id, name, dots, created, updated, webhook_url?, email? }. Keep list_id — list_alerts needs it. Errors: 403 without a paid key; 400 on invalid DOTs, empty list, or exceeding the tier cap (message says which); 401 bad key.

• list_alerts unknown never probed

  Retrieve the alert history for a saved carrier list (see save_carrier_list), newest first. Requires the same paid API key that saved the list. Each alert records one change detected between consecutive daily scoring runs for one carrier: type (oos_order_activated, authority_lost, insurance_lapsed, status_changed, inspection_risk_jump, crash_risk_jump, score_jump, reincarnation_link), severity (critical / high / medium / low), the field that changed with its before/after values, the DOT and legal name, and the scoring dates compared. inspection_risk_jump / crash_risk_jump (index base up >= 10 points, medium) are the primary deterioration signals; score_jump on the legacy composite is emitted at low severity for backward compatibility. Use it to answer "did anything change on my carrier list?" — critical alerts (new OOS order, authority lost) mean the carrier should not be dispatched until verified; follow up with carrier_score or montgomery_file for the full picture. Args: - list_id: the lst_... id returned by save_carrier_list - since (optional): YYYY-MM-DD; only alerts from scoring runs on/after this date Returns JSON: { list_id, since, count, alerts: [{ ts, as_of, prev_as_of, list_id, list_name, dot, legal_name, type, severity, field, before, after }] }. An empty alerts array means no monitored change since the given date (alerts only exist once two daily scoring runs have happened). Errors: 403 without a paid key; 404 if the list id is unknown for this key; 400 if since is not YYYY-MM-DD.

• verify_evidence unknown never probed

  Verify an archived Montgomery evidence report by its audit entry id: CarrierScore re-reads the immutable stored copy, recomputes its SHA-256 and reports whether it matches the hash recorded at generation time (and, optionally, a hash the caller supplies — e.g. the sha256 printed on a broker's filed copy). Requires the same paid API key that generated the report. Use it when a broker or auditor needs to prove that a filed evidence report is exactly what CarrierScore produced on the stated date. match=true means the archived report is byte-identical to what was served; match_supplied compares against the caller's own hash. Follow up with the audit_entries list to find ids, or with montgomery_file to generate a fresh report. Args: - entry_id: the audit_entry_id returned by montgomery_file (also listed by audit_entries) - sha256 (optional): a 64-hex SHA-256 to compare against the archived report (text or canonical json) Returns JSON: { entry_id, dot_number, generated_at, scored_as_of, score_version, format_requested, sha256_stored, sha256_computed, match, sha256_json_stored, sha256_json_computed, match_json, sha256_supplied?, match_supplied? }. Errors: 403 without a paid key, or (Monitor tier) if the entry is older than the 90-day retrieval window; 404 if the entry id is unknown for this key.
