# TruthBear RWA Region Gauge > TruthBear RWA Region Gauge is a paid API for AI agents from api.truthbear.co, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14). Runs a sequential 3-leg stress chain on a tokenised real-world asset (RWA) issuer or pool, progressing from leading credit stress signals through current pool state to realized lifecycle events like default, wind-down, or redemption freeze. ## Facts - Endpoint: GET https://api.truthbear.co/gauge/rwa-region - Price: $0.25/call - Payment: x402 - Status: unknown - Last checked: 2026-09-14 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/truthbear-rwa-region-gauge-2e264bea - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_aSqS_Ydl5HCLmPUk_AUGM 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-rwa-region-gauge-2e264bea ``` Example prompt: Run the 3-leg RWA stress chain on the Maple Orthogonal pool and tell me which legs are lit — I want to see whether there are leading credit stress signals, what the current pool state is, and whether any lifecycle events like default or redemption freeze have been confirmed. ## When to prefer this Use this endpoint when you need a structured, sequential stress-chain assessment of a specific tokenised RWA issuer or pool — covering credit stress signals, live pool state, and lifecycle events like default or redemption freeze in a single call. Prefer this over generic DeFi monitoring tools when the asset is a tokenised real-world asset (e.g. treasury funds, credit pools) and you need onchain plus issuer disclosure signals combined. Use sibling endpoints like gauge/defi-lending-chain for pure DeFi protocol risk, or gauge/history-series for time-series export of the same signals. ## Known failure modes - 422 no_charge returned when no data is available for the requested entity — not billed - Invalid or unrecognized entity identifier causes rejection - Entity identifier not in supported catalog (see GET /gauge/catalog) - Network timeout or upstream onchain data unavailability - Payment not processed (x402 protocol failure) — call not executed ## How this service works [3-LEG] Tokenised RWA chain, one issuer or pool (?entity=maple-orthogonal-pool): leading credit stress signals -> current current pool state -> realized lifecycle to default, wind-down or redemption freeze (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: issuer disclosures and onchain data. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call. ## Output A JSON object representing a sequential 3-leg stress chain: Leg 1 covers leading credit stress signals (e.g. issuer disclosures, onchain indicators), Leg 2 covers the current pool state, and Leg 3 covers realized lifecycle events such as default, wind-down, or redemption freeze. A confidence value reflects how many legs are lit in sequence. Returns 422 with no_charge if no data is available for the entity. ## Request schema (JSON Schema) ```json { "$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": [ "blackrock-buidl", "ondo-ousg", "ondo-usdy", "franklin-benji", "superstate-ustb", "hashnote-usyc" ], "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-rwa-region.input.json", "shown": 6, "total": 20 } } }, "additionalProperties": false } } }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "const": "json" }, "example": {} } } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "legs": { "lifecycle": { "band": "operating", "source_ref": "https://securitize.io/", "record_hash": "sha256:b867e29e85d48876b2a30e3c6114040eea2abf4545f07fa1aec5bfff68ec9995" }, "exposure_cascade": { "band": "contained", "source_ref": "https://securitize.io/", "record_hash": "sha256:89d033d7b208d3eee41f56713132616e7e60c789158f6445618ef9db8193b7dc" }, "redemption_stress": { "band": "clearing", "source_ref": "https://securitize.io/", "record_hash": "sha256:257c1fd97e6dc6361ae02962f73b2db5d4738570635e784cdc9e2205410634d3" } }, "name": "BlackRock BUIDL", "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": "blackrock-buidl", "nature": "This API supplies data organisation and trend description only.
