# TruthBear Promise-Reconciliation Chain > TruthBear Promise-Reconciliation Chain is a paid API for AI agents from api.truthbear.co, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-15). Runs a three-leg sequential chain assessing whether a tech product or company kept its promises, checking schedule slippage and spec shrinkage, then current status, then final lifecycle outcome (death or acquisition). ## Facts - Endpoint: GET https://api.truthbear.co/gauge/promise-region - Price: $0.25/call - Payment: x402 - Status: unknown - Last checked: 2026-09-15 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/truthbear-promise-reconciliation-chain-b92c20a7 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_FSynZ-EK4_Q-FewUwYUHC Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability truthbear-promise-reconciliation-chain-b92c20a7 ``` Example prompt: Run the promise-reconciliation chain on the Humane AI Pin — I want to see if it slipped its schedule, shrunk its specs, and whether the company is still alive or got acquired. ## When to prefer this Use this endpoint when you need a structured, source-backed sequential assessment of whether a specific tech product or company delivered on its public promises, and what happened to it over time. Prefer this over general web search when you need a confidence-scored, multi-leg lifecycle verdict (slippage → status → outcome) rather than raw news. Best for AI hardware, robotics, and consumer tech entities that made public launch promises. Not suitable for financial forecasting or investment advice. ## Known failure modes - 422 no_charge returned when no data exists for the requested entity — not billed - Invalid or unrecognized entity ID returns an error; use /gauge/catalog?signal_id= to retrieve valid entity IDs - Partial chain results if only some legs have confirmed data — confidence score reflects lit legs only - Legs may be unlit if official announcements or registry sources haven't confirmed a stage yet ## How this service works [3-LEG] Promise-reconciliation chain, one promisor (?entity=humane-ai-pin): leading promise slippage - schedule slipping, spec shrinking, promise page vanishing -> current current company or project status -> realized lifecycle to death or acquisition (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: official announcements and registries. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call. ## Output A sequential three-leg chain result: Leg 1 covers leading promise slippage signals (schedule slipping, spec shrinkage, promise page disappearance); Leg 2 gives current company or project status; Leg 3 confirms lifecycle outcome (death or acquisition as a confirmation gate). Confidence score reflects how many legs are lit in order. Returns 422 with no_charge if no data is available. Descriptive only — no forecasts or financial advice. ## Request schema (JSON Schema) ```json { "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": { "input": { "type": "object", "required": [ "type", "method", "queryParams" ], "properties": { "type": { "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [ "entity" ], "properties": { "entity": { "type": "string", "examples": [ "figure-ai", "tesla-optimus", "1x-technologies", "sanctuary-ai", "humane-ai-pin", "rabbit-r1" ], "description": "required - monitored object id, paired with signal_id; free list at GET /gauge/catalog?signal_id= -> signals[0].entities[]", "x-accepted-values": { "all": "https://api.truthbear.co/schemas/gauge-promise-region.input.json", "shown": 6, "total": 17 } } }, "additionalProperties": false } } }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "const": "json" }, "example": {} } } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "legs": { "slippage": { "band": "watch", "source_ref": "https://www.figure.ai/news/helix", "record_hash": "sha256:58fc26b76b6afae2f34d4e9029eeae7718a1840698b9330012eb86a6c2cfe731" }, "lifecycle": { "band": "operating", "source_ref": "https://www.figure.ai/", "record_hash": "sha256:27c96ce9c4f61655c3b859771fecf63efe9e1c9c2c5d0c427636e42be79fa0dc" }, "delivery_recon": { "band": "major-gap", "source_ref": "https://www.figure.ai/", "record_hash": "sha256:c4efb4f43f8585531135b8072b2ff11e9ae0a1e5bdab357b5ad871ff8f72ca5d" } }, "name": "Figure AI", "grade": "screening-level, not decision-grade", "scope": { "full": "https://api.truthbear.co/scope/v1", "verifiability": "unknown", "monitoring_not_forecast": true, "intelligence_not_command": true }, "entity": "figure-ai", "nature": "This API supplies data organisation and trend description only.
