The pipe
The one ack-and-delivery queue under the layer: send an envelope to any venue, chain or agent, read its inbox, ack what you received, and read where each message sits under the root. Every state change is a leaf of the superroot.

Try it
What the pipe holds now, and one envelope: a delivery addressed to an agent id, pulled from that inbox, then acked. The key is a free one (POST /v1/register). The payload is any text; its keccak digest is filled when you send none. Reading an inbox takes a key too, and wait (up to 25 s) holds the read open until an envelope lands; the off-box signer's own inboxes answer only the key they name (403 inbox_private to any other).

Each row is generated from the table that routes /v1. The answer of each operation, field by field, is in the OpenAPI document; see Reference.
| Operation | What it does | Auth |
|---|---|---|
GET /v1/pipe/stream | The pipe’s subscription stream as Server-Sent Events: every envelope, ack, leaf and batch that matches your filters, replayed from a sequence number and then live. | key optional |
POST /v1/pipe/send | Send one envelope (taifoon.pipe.envelope.v1) into the coord pipe: it is queued for its carrier and every state it passes becomes a leaf. | key |
GET /v1/pipe/inbox/:who | A receiver’s inbox: the envelopes delivered to an agent (erc8004:<chain>:<id>) or a venue that it has not acked yet. | key |
POST /v1/pipe/ack | Ack a delivered envelope: an envelope of kind ack with reply_to and the receiver’s receipt over Ack(envelopeId, payloadDigest, at). | key |
POST /v1/pipe/keys | Publish the X25519 key senders seal envelopes to (sealed envelopes, a Team and Protocol plan feature): a statement signed by the receiver’s identity key. | key |
GET /v1/pipe/keys/:who | A receiver’s signed X25519 key statement, to seal an envelope to it. | none |
GET /v1/pipe/status/:id | One envelope’s state and every leaf it left, each with its batch root and, once pushed, the superroot and the path to it. | none |
GET /v1/pipe/lost | Every envelope not delivered or not acked within its ttl: nothing is lost silently. | none |
GET /v1/pipe/dead | The dead-letter: every dropped envelope and the handler that ran (refund · redirect · dead-letter). | open read; writes keyed |
GET /v1/pipe/batches | The passes’ batch roots: one root over every leaf of the pass, attested once by the vault, pushed under the superroot by the sync loop. | none |
GET /v1/pipe/twigster | Twigster: every outgoing envelope is signed by its actor’s session key, certified once per hour by the Taifoon vault key that attests (it lives in a secure sandbox and never leaves it); mode, live sessions, certificates, the issuer. | none |
GET /v1/pipe/twigster/certs/:ref | One Twigster session certificate by the cert_ref a signed envelope names, to verify its signature offline (issuer signature, validity, scope). | none |
GET /v1/pipe/turbine | Deprecated alias of pipe/twigster (kept for one release). The signing turbine: every outgoing envelope is signed by its actor’s session key, certified once per hour by the Taifoon vault key that attests (it lives in a secure sandbox and never leaves it); mode, live sessions, certificates, the issuer. | none |
GET /v1/pipe/turbine/certs/:ref | Deprecated alias of pipe/twigster/certs/:ref (kept for one release). One session certificate by the cert_ref a signed envelope names, to verify its signature offline (issuer signature, validity, scope). | none |
GET /v1/lambda/catalog | The lambda catalogue: for every canonical record type (job, agent, offer, verdict, settlement, order, …) the transformation into a sendable envelope and back — the envelope kind, the transition it names, who signs, the Rust (coord-core), TypeScript (t.coord.envelope) and proto faces, the vector that pins them — plus the aggregations the twig system folds and every venue adapter’s four transforms. Filters: ?entity= ?connector= ?kind= ?summary=1. | none |
GET /v1/lambda/components | The Lambda Studio component catalogue: every ready piece a Taifoon Lambda or a studio flow may be built from, native (coord RPC, the stream, the carriers, the vault signer guard, the Pons v2 venue, the market makers, the solver) and borrowed (Relay, LI.FI, Across, deBridge, Mayan, GOAT plugins, AgentKit, x402, Pons and pump.fun references), each with its source, licence, reuse mode (code · api · reference: code only under a permissive licence), the chains it serves and where it plugs into Taifoon. Filters: ?kind= ?chain= ?native=1. | none |
GET /v1/lambda/golden | The five golden networks that work always (Solana, Robinhood Chain 4663, Base, Arbitrum, Arc): per network the six measured capabilities (read, quote, route, settle, fuel, stream) with the components behind each (two independent ones for quote and route), and the gas floor of every service signer acting there, computed from the measured gas price. Anything short of live names its reason and next step. ?chain= one network. | none |
GET /v1/lambda/flows | Lambda Studio flows: Taifoon Lambdas drawn as n8n-like DAGs of catalogue components (trigger · read · quote · route · guard · act · settle), every act behind the vault's signer guard and signing only what its lambda's acts allow, plus the registered Taifoon Lambdas they compile to (triggers, reads, acts, signed limits, guards, what the vault owns). The builder's workspace layout and commands (taifoon-sdk lambda flow check|compile|n8n). | none |
GET /v1/pipe/dropped | The dropped envelopes classified by their language type: kind, entity (from the transition they name), venue and reason class, each with its count, a sample, the wiring cause and its fix. Admin only. | open read; writes keyed |
GET /v1/pipe/twigs | Every Twigster actor’s twig by class (_TWIG_CLASSES_v1_, docs/TWIGSTER.md §7.1): the two classes the language defines (permanent: every twig kept for good, any index provable, the head anchored under the superroot; transient: a bounded ring whose rows expire after a TTL), the actor rules (upgrades:<chain> for a chain’s upgrade records, signals:<topic> for broadcast signals) and each actor’s count, signed head, oldest twig retained in memory and rows TTL. | none |
GET /v1/pipe/twigs/:actor | One actor’s twig described: its class, count, head, oldest twig retained in memory and rows TTL — for example upgrades:36927, the devnet’s upgrade twig. | none |
GET /v1/pipe/twigs/:actor/proof/:twig | _TWIG_PROOF_PUBLIC_v1_: the inclusion proof of one twig in an actor's Merkle Mountain Range (the per-actor MMR of flush roots the Twigster signs, docs/TWIGSTER.md §7), with the actor's last signed head. A twig is addressed as <actor>#<twig> (taifoon#242700, directory:x402-base#3, upgrades:36927#0). Hashes only; keyless. The twig hash itself comes from the record that names it (a signed envelope's turbine record): siblings fold it to its peak, the peaks bag to the signed head. | none |
GET /v1/pipe/bench | _PIPE_LIVE_BENCH_v1_: the latest benchmark of the coord pipe, run read-only by coord coordpipe/bench/live (keyless public /v1 reads, loopback reads on the pipe's own host, its journal and Prometheus, the in-process micro benches): ingest throughput, ack latency p50/p95/p99, fold time per batch, search latency by query type, proof and twig lookups, stream delivery, memory per 100k leaves, start to ready. Every row names its source; a source that did not answer is status dead with its reason (shown as —), never a stale number. A generated constant (register/bench/pipe-bench.json): its age is now − finished_at. Keyless. | none |
GET /v1/pipe/queues | The settlement queues of every chain.: READ (what the lanes observed), SIGN (waiting for the Twigster signature), SETTLE (signed, waiting for a settler) and ACK (sent, waiting for the chain's inclusion), per chain and venue, with depth, the oldest age, declared value waiting and the last errors. Views of the one pipe, not separate queues. ?chain= filters (eip155:8453 or 8453). | none |
GET /v1/pipe/queues/detail | The settlement queues with the oldest envelope ids of every chain × queue × venue cell (?detail=N, at most 50). Owner only. | open read; writes keyed |
GET /v1/pipe/claimable | The public SETTLE queue: the signed settle and release envelopes any settler may submit now, oldest first, each with its leaves, deadline and the plan the pipe's carrier priced: every call with who may send it, to, data, gas and fees. Calls whose who is anyone (and a wallet's own signed transaction) are open: submit one, then report it with pipe/settled. A sealed envelope's plan is withheld. | none |
POST /v1/pipe/settled | An outside settler reports the transaction it submitted for a claimable envelope. Nothing moves on the report: the carrier reads the receipt, and a successful transaction that is the plan's call (or the wallet's own bytes) delivers the envelope; the chain's inclusion acks it. The first valid inclusion wins; a later one is recorded and changes nothing. At most 5 reports per envelope. | key |
GET /v1/pipe/stats | The pipe’s counts: envelopes by state, kind and carrier; the delivered ones with their evidence; the adverts generated, delivered, acked, converted. | none |
GET /v1/pipe/volume | What went through the layer, summed from the envelopes themselves.: envelopes, base units, USD, the layer's cut, venue fees, reseller markup and seller share per venue, asset, kind and state. Filters: venues, from_venues, to_venues, topics (= to_agents; bridge.* by prefix), chains (CAIP or a bare EVM id), assets, kinds, states, window (1h, 24h, 7d, 30d, all) or since/until; group_by (from_venue, to_venue, to_agent, asset, kind, state, chain) and an optional step for a series. | none |
